Does electromagnetic radiation from wind turbines pose a threat to human health?

Electromagnetic fields (EMFs) from wind turbines are well below international exposure safety limits.

Wind turbines produce EMFs mainly from their electrical equipment. Multiple studies have found their strength to be lower than everyday exposure to many common household appliances, such as microwaves and vacuum cleaners.  

In a field study at a Canadian wind farm, average magnetic fields at the base of operating turbines were around 0.1 microtesla (µT) and dropped to background levels within 2 meters. Turbines under high wind and low wind conditions emitted equivalent levels of radiation. Another 2020 study found wind turbines produced under 0.1 µT at 4 meters distance.

For comparison, an electric can opener measures about 60 µT at 6 inches but 0.2 µT at 4 feet. International guidelines set a safety reference level of 100 µT at 50 Hz, far above the turbine measurements reported in field studies.

This is a re-post from Yale Climate Connections by Rafael Méndez Tejeda

El Niño is (probably) coming back later this year.

And this time, it’s unfolding against a backdrop of unusually warm oceans and an even warmer climate system than the last time we experienced this natural climate pattern.

Here is what you need to know about it.

What is El Niño?

The term El Niño is part of a broader phenomenon called El Niño-Southern Oscillation, or ENSO. It’s a recurring climate pattern involving changes in sea surface temperatures across the central and eastern tropical Pacific.

Copernicus, a European climate data service, reported that in March 2026, the average sea surface temperatures in the Pacific reached 20.97°C – the second-highest value ever recorded for March, which suggests a likely transition toward El Niño conditions.

The El Niño-Southern Oscillation is one of the planet’s most important natural mechanisms through which the ocean and atmosphere exchange energy and reorganize the global climate from year to year.

The phenomenon has three phases: the warm phase is El Niño, the cool phase is La Niña, and between the two lies a neutral or transitional phase, when neither dominates clearly. The changes occur in the tropical region of the Pacific Ocean, within 700 miles of the equator.

The consensus among climate models – including those from NOAA – indicates with high probability the onset and subsequent intensification of El Niño starting in fall 2026, with some models suggesting it could be an unusually intense event.

We can anticipate more heat waves with a strengthening El Niño, along with more extreme events ranging from heavy rainfall to drought. El Niño tends to intensify the subtropical jet stream, favoring wetter conditions and greater storm activity across the southern United States and northern Mexico, while the northern United States and Canada experience a relatively warmer and drier pattern, affecting snow cover and water availability. At the same time, the effects of El Niño usually reduce the frequency and intensity of hurricanes in the Atlantic Ocean.

The return of El Niño is not synonymous with climate change

El Niño is a natural phenomenon of the ocean-atmosphere system. But when it coincides with a planet already warmed by human activity, its effects can be amplified. The World Meteorological Organization warned that during the last El Niño period (2023–2024), the combination of El Niño and climate change hit Latin America and the Caribbean with greater force, worsening droughts, heat waves, wildfires, extreme rainfall, and other impacts with significant human and economic costs.

El Niño affects more than the Pacific region

Although El Niño originates in the equatorial Pacific Ocean, its effects extend to other regions of the planet through processes known as climate teleconnections – atmospheric links that allow massive cloud formations to develop as a result of the enormous evaporation generated by the warming of ocean waters.

El Niño disrupts what is known as the Walker Cell or Walker Circulation, a tropical atmospheric circulation system that transports heat, moisture, and energy on a large scale. These disturbances propagate through the atmosphere in the form of planetary waves, modifying global pressure and wind patterns. As a result, El Niño’s influence reaches the Atlantic Ocean and the Caribbean, where significant changes in regional climate occur.

Among these effects are a tendency toward drier conditions in certain periods due to descending air and a redistribution of heat that contributes to higher temperatures and more intense heat waves. In short, even though El Niño occurs far from where most Yale Climate Connections readers live, its impact is clearly felt because Earth’s climate system is interconnected, and atmospheric disturbances can travel vast distances.

During El Niño, increased variability in wind direction and speed – which inhibits hurricane formation – can act as a buffer against hurricane activity. However, hurricane formation in the Atlantic depends on multiple factors, including conditions in the Atlantic itself – such as sea surface temperatures, atmospheric moisture, and the Azores High, a large semipermanent center of high atmospheric pressure that sits over the North Atlantic near the Azores islands. And when it comes to hurricanes, we should never let our guard down completely.

In general terms, precipitation tends to be greater during La Niña or neutral years than during El Niño years. This does not mean the disappearance of all rainfall. But it does suggest a greater probability of rainfall deficits, water stress, and, in some cases, the development of drought conditions – which could worsen the drought already affecting Southern and Western U.S. states.

El Niño is not here yet

According to the most recent diagnostic discussion from NOAA’s Climate Prediction Center, current conditions are ENSO-neutral. That same assessment indicates that neutral conditions are likely through May, April, June, and July 2026, potentially extending through September, at which point a transition to the warm phase of ENSO could begin. All forecasting centers emphasize that significant uncertainty remains regarding its ultimate intensity.

El Niño does not arrive on a fixed schedule

Both NOAA and other scientific bodies agree that it appears irregularly, generally every two to seven years, though the average tends to fall closer to every three to four years. Episodes typically last between nine and 18 months, and in some cases, somewhat longer due to the effects of global warming.

The Perils of Climate Catastrophism: A Call to Situate Crisis and Change, Bickerstaff, Wiley Interdisciplinary Reviews Climate Change

Catastrophic imaginaries are inextricably bound to how we think about climate change and also how we respond—individually and collectively—to the urgent challenges of achieving rapid reductions in greenhouse gas emissions. This advanced review reflects on, and problematises, the power and persistence of ideas about climate catastrophe. It is argued that this politically and culturally dominant framing of imminent planetary devastation impedes and constrains action on climate change. It is a position that underlines, I suggest, a need to rethink and better situate our narratives of, and relations to, climate crisis and emergency. I pursue this argument in four parts. First, I begin by introducing and theoretically contextualizing “environmental catastrophism”. Second, and following on, I address the ways in which the problem of climate change has become synonymous with imaginaries of apocalyptic catastrophism, tracing dominant tropes and discourses. In the third step I raise interconnected perils of the catastrophic gaze for climate action: the impossibility of solving a problem framed as a predominantly totalising whole-planet challenge; defeatism that displaces action to “total” and/or depoliticising solutions; and public despair around, and alienation from, climate action. Finally, and in response to these challenges, I make the case for a situated view of climate crisis and change—one that offers and embraces imaginaries that are fundamentally partial, located and positioned.

Unseen but increasing: recent changes in risk of extreme precipitation over Southern Africa and Southeast Asia, Perez et al., Weather and Climate Extremes

There is evidence that rainfall extremes have become more intense and frequent over the last few decades, but it is difficult to assess these changes due to the limitations of our short observational records. We use the UNprecedented Simulated Extreme ENsemble (UNSEEN) approach to (1) assess changes in extreme rainfall over Southern Africa and Southeast Asia over the last 40 years and (2) identify locations that have a high chance of breaking rainfall records. We find that extreme rainfall risk has already increased since 1981 during the rainy season in both regions, including a doubling of risk in some months for many major population centers such as Phnom Penh, Vientiane, Bangkok, Hanoi, Maseru, Johannesburg, Lilongwe, and Lusaka. The pattern of increasing risk of extreme rainfall is projected to increase further in the coming 20 years in the CMIP6 ensemble; yet UNSEEN estimates of changes from the last 20 years are already greater than these future projections in the Philippines, northern Mozambique, and northern Madagascar. Finally, we compare the UNSEEN ensemble to historical records to identify places that have “soft records” and are likely to see record-setting events. These places with increasing risks but no recent extremes are labeled as “sitting ducks” in today's climate. We find that much of Mozambique, the Philippines, and Laos would be considered “sitting ducks” for extreme precipitation in at least one month of the year. Disaster risk managers should use these types of large ensembles when estimating the risk of extremes in today's climate, in order to ensure that society is prepared for record breaking events. This approach can also be used for improving engineering design estimates of rainfall return periods and for stress-testing health system and disaster preparedness.

Facilitating permanent carbon storage through risk transfers? Analyzing the insurability of the carbon leakage liability, Spencer et al., Energy Research & Social Science

Geological storage of CO2 is expected to play a role in mitigating climate change, especially for carbon capture and storage (CCS) in hard-to-electrify sectors, and for carbon dioxide removal (CDR) under net-zero targets. One challenge of geological CO2 storage is the risk that CO2  later returns to the atmosphere. Policymakers aim to address this risk by imposing  leakage liabilities on storage operators, potentially also mandating insurance cover. However, whether such liabilities are insurable is still open given the undeveloped state of the insurance market for this risk. Here, we adapt the Berliner (1982) framework from insurance economics to this question, to consider actuarial, market, and social factors that might constitute barriers to insurability. Due to the lack of a loss history, we systematically use the upstream oil & gas industry as an analogy. Combining expert workshops and techno-economic estimates, we find two barriers: the possibility of correlated material failures across the industry and gradual leakages, which will likely have to remain uninsured initially (though increased experience will likely improve the situation). We also find three general preconditions for insurability: appropriate care in site selection, robust regulations for information sharing and risk mitigation, and limited coverage periods to exclude CO2 price volatility. Overall, the insurability of CO2 leakage does not appear to be a roadblock for the deployment of CCS and CDR. The future price of CO2 emissions and removals, however, remains an important uncertainty. ‘In-kind’ insurances (based on reserve CO2 units) are a possible way out.

Dust Decline Amplifies High-Cloud Ice-to-Liquid Transition and Buffers the Radiative Feedback Under Warming, Wang et al., Geophysical Research Letters

The response of the cloud phase to global warming is a critical yet poorly constrained component of Earth's climate sensitivity. While rising temperatures drive a thermodynamic transition from ice to liquid clouds, the role of ice-nucleating particles in modulating this shift remains underexplored. Here, we provide evidence that the declining trend of mineral dust in the Northern Hemisphere (NH) may act as a microphysical amplifier of this transition. Satellite observations of high clouds (

Opposing transient and equilibrium effective radiative forcing from aerosol-cloud interactions, Dagan, Nature Communications

Aerosols influence clouds, and therefore Earth’s radiation budget, through processes that operate across multiple and interacting time scales, making aerosol-cloud interactions (ACI) a persistent source of uncertainty in estimates of effective radiative forcing (ERF). Here we examine the time-dependent response of the local, convection-focused ERFACI using an ensemble of high-resolution simulations initialized from different atmospheric states and subjected to an instantaneous aerosol perturbation, together with simulations in which aerosol concentration changes with prescribed periods. We find that the transient ERFACI during the first  ~ 2 days is positive, driven by rapid microphysical invigoration, enhanced high-cloud fraction, and increased longwave trapping. In contrast, the equilibrium ERFACI becomes negative as upper-tropospheric warming increases static stability and reduces anvil cloud fraction. As a result, the time-mean forcing depends on the ratio between the environmental adjustment time scale (τadj) and the aerosol-perturbation time scale (τaer). For intermediate regimes, where τaer is only moderately longer than τadj, the system exhibits pronounced hysteresis: ERFACI depends not only on the instantaneous aerosol loading but also on its recent history. These results imply that snapshot-based observational constraints and near-instantaneous-equilibrium convective parameterizations may systematically misestimate ERFACI.

Pedal to the Metal 2026. The iron and steel industry’s coal lock-in crisis, Grigsby-Schulte et al., Global Energy Monitor

The authors present the newest annual survey of the current and developing global iron and steel plant fleet. The authors examine the status of the iron and steel sector compared to global decarbonization roadmaps and corporate and country-level net-zero pledges. Included in the survey are asset-level data on 1,293 iron and steel plants in 91 countries and nearly 700 operating and proposed mines worldwide. A closing window for transition With 2030 decarbonization deadlines approaching, the global iron and steel industry is running out of time to shift away from coal-based production methods. Continued investment in coal-based capacity and underinvestment in green hydrogen threaten net-zero targets. Now more than ever, it is crucial to disrupt emissions-intensive blast furnace developments and redirect resources to iron and steelmaking technologies that align with net-zero goals.

Trust, Governance, and Climate Disasters in the Indo-Pacific, Sohail Akhtar, Toda Peace Institute

The author argues that climate emergencies generate epistemic stress: situations in which uncertainty and competing narratives disrupt shared understandings of risk and appropriate response. Drawing on recent bushfire events and subsequent reviews of disaster governance in Australia, the author shows how disagreements over climate attribution, institutional readiness, and political accountability can complicate emergency coordination and weaken public trust even where operational capacity remains strong. The author concludes with policy recommendations for Indo-Pacific governments, regional organizations, and international partners aimed at strengthening crisis communication, institutional credibility, and the capacity of democratic systems to manage contested knowledge during climate emergencies. 129 articles in 63 journals by 1077 contributing authors

Articles/Reports from Agencies and Non-Governmental Organizations Addressing Aspects of Climate Change

24/7 renewables: The economics of firm solar and wind, Dardour et al., International Renewable Energy Agency

The authors' analysis shows that the cost of firm renewable electricity has declined rapidly across all major technologies and markets. In high-quality solar and wind resource regions, co-located hybrid systems can already deliver round-the-clock electricity at costs competitive with - and in many cases below - those of new fossil-fuel generation. China currently defines the global cost floor, while costs in Brazil, India, South Africa, Australia, and the Gulf region are declining rapidly towards fossil-fuel cost parity. The authors identify key drivers of firm renewable costs – technology performance, resource quality and system configuration – and examine the policy levers that are proving decisive in translating cost competitiveness into deployment at scale. They conclude that the technologies are maturing, the costs are falling and the commercial demand is growing. The pace at which firm renewable electricity is deployed will be among the most consequential determinants of the global energy transition in the decade ahead.

Powering Reliability Through Market Design. Addressing Rising Demand and Constrained Supply, and Stimulating Investment to Support Durable Reliability, PJM

For two decades, the PJM region managed its electricity system in an era of relative stability. The Reliability Pricing Model, PJM’s capacity market, was built for that environment: a system with predictable, gradually changing load; a coal-to-gas fuel transition that could be managed over a years-long horizon; and a generation development timeline that aligned with the market’s three-year forward horizon. The PJM region is now navigating a convergence of three structural forces that have pushed the system into disequilibrium: an unprecedented surge in demand driven by the rapid expansion of large-load data centers and broader economy-wide electrification; the accelerated retirement of dispatchable generation due to environmental policy and economics; and significant supply chain and permitting frictions that have extended the time required to bring new resources online. The PJM Board of Managers directed PJM staff to undertake a holistic review of the capacity market design and investment incentives. The Board recognized that the market’s current price volatility – while economically rational – is placing unsustainable stress on the governmental compact that allows the market to function, and that the foundational assumptions of the Reliability Pricing Model design must be reexamined in a resource-constrained world. This white paper is PJM’s response to that directive.

Homegrown Energy: A policy blueprint for energy affordability, Eberhard et al., Rewiring America

A coordinated set of policies can make whole-home electrification, rooftop solar, and battery storage affordable for 96 percent of eligible U.S. households, delivering $26,000 in average lifetime savings per home, or $1.5 trillion nationwide. Home electrification alone is affordable for roughly 40 percent of U.S. households. By reshaping incentives and economics to capture the value of household energy infrastructure, policymakers can shift affordability from 1 in 10 eligible households to more than 9 in 10. The authors identify six market-based policies that lower costs, bring in new capital, and ensure households are paid for the value they provide; reduce soft costs; require large new energy users to invest in distributed resources; enable inclusive utility investment; modernize rate design; redirecting gas infrastructure investment; and scale virtual power plants.

Distributed Energy Can Unleash the Resilient, Affordable Grid of the Future, Lightbody et al., Pew Charitable Trusts

Distributed energy resources (DERs)—energy generation and storage technologies including rooftop solar, battery storage, smart appliances, and “managed” electric vehicle charging, which involves controlling when EVs are charged to account for demand on the grid—offer a low-cost, readily available, scalable solution to increased demand. To help address this demand, the authors identified three core DER policy goals and specific recommendations that can help decision-makers, including state elected officials and public utility regulators, begin the work of bringing DERs to scale nationwide; integrate DERs as core grid resources into utility planning, investment, and procurement decisions; reduce administrative, technical, and regulatory barriers to allow DERs to be permitted and granted grid access faster and at lower cost; and strengthen community resilience by using DER solutions to improve grid reliability.

Watts Wasting Texas Water. How coal and gas power plants guzzle billions of gallons every year and how we can transition to a more secure water future, Lindsay Stafford Mader, Sierra Club

Texas is facing drought, water shortages, and declining river and stream flows in all reaches of the state. Amid these ongoing water crises, it is important to understand just how much water coal and gas power plants use every year, whereas renewable energy and battery storage barely use any. To determine the enormity of water resources dedicated to Texas power plants, the author analyzed water consumption numbers from the U.S. Energy Information Administration as well as state water rights data.

Water Use Requirements for Data Centers in Texas, COMPASS Research Affiliates Program at the University of Texas at Austin

The authors address the urgent and growing need to understand and quantify the water footprint of data centers, alongside their escalating energy demands. Water has now emerged as a primary constraint in data center planning, particularly in regions vulnerable to drought, water stress, or infrastructure limitations. The adoption of water-intensive cooling systems, such as evaporative and hybrid technologies, while advantageous for energy efficiency, raises concerns over freshwater use and long-term sustainability. The authors position water not as a secondary input, but as a core engineering, environmental, and policy issue in the future of digital infrastructure.

Pipe Dreams: How Oil and Gas Fail to Deliver Economic Development in Africa, Muttitt et al., Oil Change International and Power Shift Africa

As global energy markets are rocked by conflict and geopolitical instability, the authors found that oil and gas production has failed to deliver economic development in Africa’s producing countries and is instead deepening vulnerability, inequality, and dependence. The authors use data from 13 producing countries in Africa and find that decades of extraction have failed to reduce poverty or drive economic growth, and instead are lining the pockets of an elite few.

A New Phase for the U.S. Battery Industry. Policy Considerations to Sustain Momentum, Bridge Gaps, and Avoid Pitfalls, Ray Cai and Jane Nakano, Center for Strategic and International Studies

Drawing on extensive desk research and stakeholder interviews, the authors use their report to inform policy debates through evidence-based analysis of the complex dynamics that are shaping the industry at today’s critical inflection point. The authors focus on three central strategic questions: where are the most critical supply chain vulnerabilities, what should be the approach to international linkages, and how can innovation be aligned with industrialization?

Offshore Wind: Status and Issues for the 119th Congress, Clark et al., Congressional Research Service

The U.S. offshore wind industry has faced economic challenges in recent years that have led to the postponement or cancellation of some projects. Projects also have faced lawsuits from coastal homeowners and preservationists, the fishing industry, tribes, and those concerned about potential impacts to marine wildlife. Recent federal policies toward U.S. offshore wind have shifted from those in place during the Biden Administration. President Trump has halted OCS wind leasing and permitting and directed other actions to reverse prior federal support for offshore wind. Also, in P.L. 119-21, the FY2025 budget reconciliation law, Congress limited offshore wind tax credits and rescinded unobligated balances for federally funded activities related to interregional and offshore wind electricity transmission. Congress continues to consider issues related to offshore wind leasing, permitting, transmission, tax credits, and related matters through oversight and legislation.

Hydrogen Energy: Technologies Offer Potential Benefits but Face Challenges to Widespread Use, Fletcher et al., Government Accountability Office

Hydrogen energy technologies offer long-duration energy storage, increased transportation efficiencies, quiet operation, reduced air polluting emissions, and potentially broad availability. For example, hydrogen fuel cell power generation technologies could provide quiet, clean backup power to data centers and other large-scale operations during power outages. These generation technologies could increase overall electricity grid security by providing long-duration energy storage. Currently, hydrogen fuel cells provide about 0.03 percent of utility-scale electricity generation.

Trust, Governance, and Climate Disasters in the Indo-Pacific, Sohail Akhtar, Toda Peace Institute

The author argues that climate emergencies generate epistemic stress: situations in which uncertainty and competing narratives disrupt shared understandings of risk and appropriate response. Drawing on recent bushfire events and subsequent reviews of disaster governance in Australia, the author shows how disagreements over climate attribution, institutional readiness, and political accountability can complicate emergency coordination and weaken public trust even where operational capacity remains strong. The author concludes with policy recommendations for Indo-Pacific governments, regional organizations, and international partners aimed at strengthening crisis communication, institutional credibility, and the capacity of democratic systems to manage contested knowledge during climate emergencies.

Taiwan’s Climate Adaptation Leadership in the Caribbean: Technology, Capacity, and Strategic Cooperation, Hernandez-Roy et al., Center for Strategic and International Studies

Climate change represents an existential threat for Caribbean Small Island Developing States (SIDS), where exposure to extreme climate events intersects with structural economic vulnerabilities, limited fiscal capacity, and high economic dependence on climate-sensitive sectors. As Caribbean states seek technical expertise in climate adaptation strategies such as water resilience, disaster preparedness, and agricultural security, Taiwan—itself an island—could be a natural partner with which to collaborate on innovative and impactful projects.

Pedal to the Metal 2026. The iron and steel industry’s coal lock-in crisis, Grigsby-Schulte et al., Global Energy Monitor

The authors present the newest annual survey of the current and developing global iron and steel plant fleet. The authors examine the status of the iron and steel sector compared to global decarbonization roadmaps and corporate and country-level net-zero pledges. Included in the survey are asset-level data on 1,293 iron and steel plants in 91 countries and nearly 700 operating and proposed mines worldwide. A closing window for transition With 2030 decarbonization deadlines approaching, the global iron and steel industry is running out of time to shift away from coal-based production methods. Continued investment in coal-based capacity and underinvestment in green hydrogen threaten net-zero targets. Now more than ever, it is crucial to disrupt emissions-intensive blast furnace developments and redirect resources to iron and steelmaking technologies that align with net-zero goals About New Research

A lot has happened since then. We’ve gotten the first three months of data in for 20261 (and have a good sense of where April 2026 will end up in reanalysis data – see our Climate Dashboard for daily updates).

More importantly, models are converging on a doozy of an El Niño event developing in the latter part of 2026, with the latest multi-model median projection of a peak anomaly of 2.7C in the ENSO3.4 region of the tropical Pacific. While the prediction remains uncertain (we remain within the “spring predictability barrier” when its historically hard to predict ENSO2 development), this would put the 2026/2027 roughly on par with the “super” El Niño the world experienced in 2015/2016.

I’ve updated the models I use for both my 2026 and 2027 projections. I’ll go into the gory methodological details shortly, but the headline numbers are in the figure below: the estimate for 2026 has risen from 1.41C (with a range of 1.27C to 1.55C) to 1.46C (1.36C to 1.59C). The 2027 estimate has similarly increased from 1.57C (1.3C to 1.76C) to 1.61C (1.4C to 1.93C).

 

So what changed? Before the start of the year I was using a pretty simple regression model. It estimate what the annual temperature anomaly would be based on the prior year’s anomaly, the last month of the prior year, the predicted ENSO state over the next three months, as well as a year count (and year count squared) to reflect linear and non-linear aspects of the trend since 1970.

I’ve updated this to use the equation below, which includes the year count, prior year’s temperature anomaly, the anomaly over the year to date for 2026 (currently Jan-Mar), the latest month, the observed ENSO state over the year to date, and the forecasted ENSO state over the remainder of the year.3 The uncertainty in the 2026 prediction also accounts for the uncertainty in the ENSO forecast using a Monte Carlo sampling approach.4

Similarly, the original 2027 calculation was pretty ad hoc; I just took the 2026 estimate and added the current warming trend (0.026C per year) that we calculated in our Forster et al 2025 paper. I then added a range of possible boosts from El Niño ranging from 0C (no El Niño develops) to 0.2C (very strong El Niño), roughly encompassing the range we’ve seen across past events.

Now I’ve converted it into a proper regression model. It calculates the expected year-over-year change in temperatures based on the year count (reflecting the trend) and the ENSO forecast for the latter part of the year (September-December, reflecting the period over which the currently developing El Niño will likely peak).5 This is then added to the 2026 estimates, with their uncertainty (and the uncertainty in future ENSO forecast) propagated through using the same Monte Carlo approach. This actually slightly increases the error bars from the original 2027 estimate, reflecting the uncertainty in both the 2026 estimate and the El Niño forecast.

One way to test how well this approach works is to see how well it predicts year-over-year temperature changes during past strong El Nino events (e.g. with a peak >2C and a Sept-Dec average of >1.5C), as shown in the figure below:

In general the model does pretty well; it slightly underestimates the year-over-year increase in 1973, 1983, and 1998, gets 2016 pretty spot on, and slightly overestimates the increase between 2023 and 2024. This is, of course, contingent on where 2026 annual temperatures end up, so a warmer 2026 in this model would result in a warmer 2027.

We can also look at how well the model “hindcasts” past years by applying the 2026 prediction model to past years using the same year-to-date and temperature and ENSO values:

Overall the development of a strong El Niño event in 2026 (and its effects on 2027 temperatures) have bumped my predictions up a bit from where they were at the start of the year.

But 2026 remains more likely than not to end up as the second warmest year on record (~56% chance), but has a non-trial chance of being the warmest year (~26%) with a somewhat larger change (34%) of being above 1.5C.

2027, by contrast, is likely (~85% chance) to be the warmest year on record and has a 88% chance to be above 1.5C. My updated estimate central estimate (1.61C) remains a bit lower than Hansen’s (1.7C),6 but its consistent with the size of the year-over-year bumps we’ve seen in past strong El Niño events.

Update:A new set of ENSO runs came in this afternoon from CanSIPS, which previously set the lower bound on the ENSO forecast for 2026. The new update has notably higher estimates; these don’t change the central estimate (as the median across all ENSO model remains unchanged), but it reduces the lower end of the uncertainties in the error bars. I’ve updated the figures and text accordingly. 1 Here I’m using the average of NASA’s GISTEMP, NOAA’s GlobalTemp, Berkeley Earth, Hadley/UAE’s HadCRUT5, and Copernicus/ECMWF’s ERA5 as they are updated monthly and reasonably reflect the diversity across GMST datasets. 2 ENSO refers to El Niño Southern Oscillation, a term that encompasses both El Niño and La Niña conditions in the ENSO3.4 region of the tropical Pacific. 3 I also tested it with year count squared but the difference was minor – the prior year and year-to-date already captures a lot of the information about acceleration. 4 This involves calculating a probability distribution of future ENSO development across all the ensemble members of all the models with runs through the end of the year, and randomly sampling 1000 times from that distribution to see how it affects the results. 5 I also tried a variant using the peak El Niño forecast, but that was slightly less predictive. 6 And his team’s new estimate, just published today, that 2026 is on track to be the warmest year on record.

This is a re-post from Yale Climate Connections

Al Gore’s climate documentary “An Inconvenient Truth” arrived in theaters 20 years ago, in May 2006. The film had a profound effect on the public’s awareness and understanding of climate change, a number of surveys found.

I count myself among those who were dramatically influenced by “An Inconvenient Truth.”

In 2006, the topic of climate change had not yet significantly breached the public consciousness. Despite having just embarked on a career as an environmental scientist and having recently completed my graduate studies with degrees in astrophysics and physics, I had only a vague notion about the problem of climate change before seeing the documentary.

I remember thinking as I left the theater, “If the science in this film is right, how is it possible that we’re not doing anything to stop climate change?” Answering this question put me on a path to becoming a climate journalist and educator.

The film was a watershed moment for me and countless others. It also retains cultural significance to this day. In an October 2025 episode of his podcast centered on climate change contrarianism, which has over 1 million views on YouTube, Joe Rogan and his guests mentioned Al Gore and his film a dozen times. That included Rogan’s claim that “What Al Gore predicted in this stupid movie, which is so far off. He thought we were all going to be dead today, right?”

Spoiler alert: That’s not right. Gore never said we would all be dead by now; Rogan made that up.

Read: Five ways Joe Rogan misleads listeners about climate change

For its 20th anniversary, I revisited the film. I found that its scientific overview was imperfect but predominantly accurate, and that despite worsening impacts, the world has made significant progress in addressing climate change over the ensuing two decades.

‘An Inconvenient Truth’ was right on the basic science

Many climate science experts have reviewed “An Inconvenient Truth,” including University of Washington climate scientist Eric Steig, who in a 2008 paper wrote that although the film included some oversimplifications, “The portrayal of the science of climate change in ‘An Inconvenient Truth’ is largely correct.”

Gore outlined the basic science underpinning climate change the same way I explain it to college students today: By burning vast amounts of fossil fuels, humans have increased the amount of heat-trapping carbon dioxide in the atmosphere. That pollution traps more heat in Earth’s thin lower atmosphere, warming the planet’s surface.

When the film was released, the atmospheric concentration of carbon dioxide had surpassed 380 parts per million, a level 36% higher than at any time in the prior 650,000 years.

To emphasize how high carbon dioxide levels could rise if fossil fuel consumption continued unabated, Gore climbed aboard a scissor lift.

“Within less than 50 years, it will be here,” he said, pointing to the top of a graph where projected concentrations reached around 500 parts per million.

Now 20 years later, carbon dioxide levels are approaching 430 parts per million, and as Gore suggested, remain on pace to reach 500 parts per million by 2056, barring successful efforts to slow their rise.

Because carbon dioxide is the principal control knob governing Earth’s temperature, as a team of NASA climate scientists documented in a 2010 study, the carbon dioxide levels and temperature have hewed closely throughout the planet’s history. As Gore accurately explained, abrupt and dramatic spikes in carbon dioxide invariably cause global warming by trapping more heat.

Shrinking glaciers

In perhaps the most oversimplified section of the documentary, Gore reviewed the declines of various glaciers around the world.

One of the most common critiques of the film lies in Gore’s discussion of the glaciers of Mount Kilimanjaro. It only lasted for 30 seconds, but Gore implied that global warming was to blame for their decline, asserting that “within the decade, there will be no more snows of Mount Kilimanjaro.”

In fact, several studies, including this 2004 paper, have found that a decline in local precipitation tied to changes in the Indian Ocean is the major cause of the mountain’s shrinking glaciers – of which some remnants remain today – although global warming is also a contributing factor.

Next, Gore claimed that within 15 years, Glacier National Park would become “the park formerly known as Glacier.”

One 2003 study did suggest that many of the glaciers in Glacier National Park could disappear by 2030 due to global warming, but fortunately, that has not quite borne out. Although the glaciers in the park continue to decline due to rising temperatures, a 2019 study estimated that it might take until 2100 for Glacier National Park to become glacierless.

But Gore was correct that global warming is causing the accelerating decline of many glaciers around the world, and that this shrinkage poses water security threats to the 2 billion people who rely on mountain glaciers for their water supply.

Worsening extreme weather

Gore also explored the links between climate change and extreme weather, describing a deadly 2003 European heat wave. A 2016 study estimated that global warming was responsible for about half the deaths in London and Paris caused by that heat wave. He also reviewed the devastating impacts of Hurricane Katrina, whose damages an analysis last year estimated climate change worsened by 25% or more.

A little later in the film, Gore outlined the threat that the Atlantic Meridional Overturning Circulation could collapse. This ocean conveyor belt transports warm and cool water through the Atlantic, Indian, and Southern Oceans. By moving warm water from near the equator to the North Atlantic, this ocean circulation helps keep northern Europe significantly warmer than it would otherwise be.

Gore explained that the last time this circulation collapsed, about 12,000 years ago – as a result of a flood of melting ice water at the end of the last ice age – temperatures in Europe plummeted. A study published last month found that the climate models that best match observational data are those that are the most pessimistic, suggesting that the circulation may seriously weaken this century to the point of potential collapse.

The film also included an overview of threats that sea level rise poses to coastal cities around the world. Ice melt from land-based glaciers and the polar ice sheets has increased over the ensuing two decades, causing the rate of sea level rise to accelerate since the documentary was filmed.

Gore also covered numerous other dangerous climate impacts, including the expanding range of infectious disease vectors like mosquitoes, the impact on species of shifting ecosystem ranges and the altered timing of seasons, and the bleaching of coral reefs and the threat it poses to marine ecosystems. All of these problems continue to worsen to this day.

More than 97% of studies agree: modern climate change is human-caused

The film described a memo from strategist Frank Luntz that had advised Republican politicians, “You need to continue to make the lack of scientific certainty a primary issue in the debate.”

In fact, by 2006, there was a strong scientific consensus that modern climate change was human-caused. In 2004, science historian Naomi Oreskes had published the first survey of the published climate science literature. Gore pointed out that in her sample of 928 peer-reviewed study abstracts, none disagreed with the consensus position that humans are causing global warming.

In a 2013 paper, my colleagues and I updated and expanded upon Oreskes’ 2004 study. We examined nearly 12,000 abstracts of peer-reviewed climate studies and invited the authors to categorize their own papers. In both cases, we found that among peer-reviewed studies that took a position on the question, over 97% agreed that humans are responsible.

Then, in 2016, we published another paper in collaboration with Oreskes and other authors of climate consensus studies, concluding that “the finding of 97% consensus in published climate research is robust and consistent with other surveys of climate scientists and peer-reviewed studies.”

More recent studies have found that the expert consensus likely exceeds 99% today, despite a few prominent figures still proclaiming it a hoax.

At times, Gore seemed discouraged by the lack of progress in addressing climate change.

“I look around and look for really meaningful signs that we’re about to really change; I don’t see it right now,” he said. But he also expressed hope, saying, “I have faith that pretty soon, enough minds are changed that we cross a threshold.”

About a decade later, 175 countries signed the Paris climate agreement. Today, every nation in the world has ratified the agreement except Yemen, Iran, and Libya – and President Donald Trump recently withdrew the United States for the second time.

The International Energy Agency estimates that since 2015, climate and clean energy policies around the world have erased a full degree from Earth’s global warming trajectory. Before the Paris agreement, countries were on a path to release enough climate pollution to cause a catastrophic 3.5-4°C global warming by 2100; today, we’re on a path toward 2.5-3°C.

Read: New report has terrific news for the climate

It’s not yet enough to meet the Paris agreement’s target of limiting global warming to “well below 2°C,” but we still have the opportunity to further reduce emissions and future warming.

In the film, Gore visited China and described the country’s coal power plant growth as “enormous.” Today, that descriptor best fits the country’s clean energy deployment. As a result, China’s climate pollution has now been flat or falling for about two years, and its clean technology exports to countries around the world are surging. In its new Global Energy Review, the International Energy Agency said that “the world has entered the Age of Electricity,” with virtually all of electricity demand growth being met by clean sources.

In short, despite a few oversimplifications, the scientific descriptions in “An Inconvenient Truth” have largely withstood the test of time, and the climate impacts outlined in the film have continued to worsen in tandem with rising global temperatures. But international agreements, domestic climate policies, and accelerating deployments of ever-cheaper clean technologies have started to bend the emissions curve downward.

I think that if Al Gore’s 2006 self were to visit 2026, although more action is still needed to meet the Paris targets, he would be encouraged by the progress humanity has made in addressing the climate crisis.

ClimateAdam - Our Oceans Are Tipped To Collapse: Can we still act?

Climate change is driving a crucial ocean current close to collapse. As global warming heats our planet, it's slowing down the vast Atlantic Meridional Overturning Circulation - or AMOC. And scientists fear that it could reach a tipping point - effectively shutting down this ocean circulation, and causing rapid climate change and disasters across the world: brutally cold European winters; sea level surges in America; and disrupted monsoon rains. But what do we actually understand about our risks of an AMOC tipping point? How big are the risks as our climate changes? And can we still act to protect ourselves?

Dr Gilbz - This critical climate system is tipping…. Or is it?

The Atlantic Meridional Overturning Circulation - or AMOC - is one of the world's most vital ocean currents, transporting water, heat and carbon around the planet. It's part of the "global conveyor belt" that keeps our planet moving.

And scientists are warning that it could be weakening - with terrible consequences for humanity.

But... is it?? What's behind the contrasting headlines? Let's dig in

This blog evolved over the week of May 4 to 8, 2026 when I was adding to it from day to day as time allowed. It may still see some updates even after fully published on our homepage as some more information becomes available.

This year's General Assembly of the European Geosciences Union (EGU) took place from May 4 to 8 2026 both on premise in Vienna and online as a fully hybrid conference. This year, I had decided to join virtually, picking and chosing sessions I was interested in. This blog post is a compilation - a kind of personal diary - of the happenings in Vienna from my perspective.

All told, 21,117 abstracts were submitted for the conference back in January and this year’s programme included over 1,000 scientific sessions, 62 short courses, 16 keynote Union Symposia and Great Debates, 38 Medal and Award lectures, as well as the Job Centre, Artists in Residence, GeoCinema, Science-Policy events and much, much more.

Monday, May 4

EGU Today

The very first session I attended at this year's EGU conference was EOS1.1 Science and Society: Science Communication Practice, Research, and Reflection which started at 8:30 in the monring and lasted until lunchtime with a 30 minutes break in the middle.

Science communication includes the efforts of natural, physical and social scientists, communications professionals, and teams that communicate the process and values of science and scientific findings to non-specialist audiences outside of formal educational settings. The goals of science communication can include enhanced dialogue, understanding, awareness, enthusiasm, influencing sustainable behaviour change, improving decision making, and/or community building. Channels to facilitate science communication can include in-person interaction through teaching and outreach programs, and online through social media, mass media, podcasts, video, or other methods. This session invited presentations by individuals and teams on science communication practice, research, and reflection.

During this session we heard about many examples of science eduction and communication in various countries (Italy, Spain, Ireland, The Netherlands, Great Britain, Belgium...), settings (schools, university, public outreach, prisons...) and topics (Climate change, natural hazards, polar science, geodesy...):

• Lorena Salgado - SmarTerrae: Applied scientific training in geoscience from the earliest educational stages 
• Gabriele Weigelhofer - Interactive wetland education: Classroom materials following a constructivist instructional framework (Horizon Europe Restore4Life) 
• Martin Sehnal - Scientific Storytelling in Geodesy: Using Cartoons, Videos, and Digital Platforms to Reach New Audiences 
• Chiara Anzolini - Speculative Storytelling as a Tool for Biodiversity and Climate Communication 
• Rob Butler - The Shear Zone Channel – reflections on sharing geological science on YouTube 
• Reinout Verbeke - Planet Belgium: narrating the geological odyssey of a country through multimedia storytelling 
• C. Nur Schuba - Using sequential art to communicate scientific ocean drilling 
• Federica Flapp - “Signals from the climate in FVG”: a magazine enhancing climate awareness and bridging the gap between science and society at the regional level 
• Rodrigo Martinez-Abarca - A guide to outreach geosciences on social media: the case of Divulgación Terróloga 
• Maria del Socorro Fonseca Cerda - From Science to Practice: Co-Designing Windstorm Hazard & Risk Information for Dutch Portals 
• Sandra Ricart - Co-Designed, Stakeholder-Driven Governance for the WEFE Nexus under Climate Extremes: Lessons from Lake Como, Italy 
• Alex Lipp - www.SewageMap.co.uk and POOPy: Open-source tools for understanding and communicating the impacts of sewage pollution on waterways in real-time 
• Tatiana Izquierdo - Access, verification, and trust in extreme weather events communication: age and discipline matter 
• Thais Siqueira - From Landscape to Geohazard: Assessing volcanic hazard communication in Tenerife geosites 
• Deniz Vural - From Network to Ecosystem: Reflecting on Early Career–Led Science Communication through APECS 
• Carla Mateus - Prison talks: bringing climate change conversations into the Irish prisons 

This session included my own presentation right in the middle before the coffee break where I talked about our website relaunch project as already mentioned in my prolog blog post. In the meantime, I created a "companion blog post" for my presentation which includes all the slides and accompanying text as well as a link to download the PDF-version.

The session ended for today - there'll be more tomorrow! - with Philip Heron giving the invited Katia and Maurice Krafft Award Lecture titled What we’ve learned from teaching people in prison to Think Like a Scientist. Here is a snippet from this abstract to give you some context

Scientific thinking requires the critical analysis of information, while science itself thrives on the diversity of ideas. Yet, science, technology, engineering, and math (STEM) subjects have historically struggled to be inclusive and accessible to students from underrepresented communities - meaning we often miss a diversity of voices. Furthermore, STEM subjects have often been rigid in their teaching structure, creating barriers to education for students with more specific (or unrecognised) learning needs.

To address this, our science outreach course Think Like A Scientist was designed to improve critical thinking and encourage independent thought by applying adaptive education practices to create inclusive and accessible classroom environments. The program started in 2017 and has been applied in several different settings (e.g., schools and adult learning centres), but has mainly featured in prisons around the world (including England, Canada, Australia, and Spain).

In the afternoon I joined session EOS4.1 Geoethics: Linking Geoscience Knowledge, Ethical Responsibility, and Action. This session was created by merging EOS4.1 (26 abstracts) Geoethics: Linking Geoscience Knowledge, Ethical Responsibility, and Action, EOS 2.6 (9 abstracts) From crisis to action: Education and communication for climate, ocean, overshoot and geoethics and EOS4.2 (7 abstracts) Geoscience research and collaboration in times of geopolitical crises.

Geoscientists play a key role in providing essential information in decision-making processes that consider environmental, social, and economic consequences of geoscience work. Therefore, their responsibilities extend beyond scientific analysis alone. Global challenges, such as climate change, resource management, and disaster risk reduction, push geoscientists to expand their role beyond research and to engage ethically in public efforts.

Geoethics provides a framework for reflecting on the ethical, social, and cultural implications of geoscience in research, practice, and education, guiding responsible action for society and the environment. It also encourages the scientific community to move beyond purely technical solutions by embracing just, inclusive, and transformative approaches to socio-environmental issues.

Furthermore, science is inseparable from social and geopolitical contexts. These conditions shape what research is funded, whose knowledge is valued, with whom we collaborate, and who has access to conferences. As Earth and planetary scientists, we must consider the human and environmental consequences of our work. This is especially true in Earth observation, where many satellites have both scientific and military applications, and where scientific tools have at times enabled ecocide and resource exploitation under neocolonial systems.

This session will offer insights and reflections across a wide range of topics, from theoretical considerations to case studies, foster awareness and discussion of sensitive issues at the geoscience–society interface and explore how geoethics can guide responsible behavior and policies in the geosciences. 

The nine presentations in the first half of the session covered a wide range of topics related to the field of geoethics. We heard about moral values in the scope of ecosystems and biodiversity, about creating a new curriculum for ethical awareness in Ghana, about respecting indegenous knowledge in Australia in the era of big data, about turning sustainability into practice, about a workers.coop in the UK creating data tools for scientists, about avoiding "impact washing", about the ethical usage of AI and LLMs, about the ongoing anthropocene debate and the needed ethical framework for climate intervention research:

EGU Today

Tuesday morning started at 8:30 with the 2nd half of EOS1.1 Science and Society: Science Communication Practice, Research, and Reflection and lasted until lunchtime with a 30 minutes break in the middle.

In the presentations before the coffee break, the speakers told us about projects in Switzerland, Hongkong, France, Japan, Greenland, Italy, the UK and the United States. We heard about projects related to food, rainfall, soil, caves, air quality, clean water and flood hydrology and how they were used in communication and outreach activities with the public.

After the coffee break we heard about AI-created virtual climate scientists, how generative AI could be utilized for paleontological communication, how some activism increases trust in climate scientists, how science communication and activism is impacted by authoritarianism and how knowledge can be made relevant for society as well as for individual choices. Last but not least, Joshua Howgeg gave the Angela Croome Award Lecture in which he talked about lessons for non-ficting writing based on his experience as a magazine editor.

After the lunch break I joined short course SC3.4 Science Diplomacy: What is it and how to engage to learn more about the overlap between science and diplomacy. This course was convened by Lene Topp, Zsanett Greta Papp, Alfonso Acosta and Noel Baker who all gave short keynote about their connections with the topic. They were joined online by Jan Marco Müller who gave a short presentation about his path from geoscientists into science diplomacy at the European Commission.

Global challenges, such as climate change and natural hazards, are becoming increasingly complex and interdependent, and solutions have to be global in scope and based on a firm scientific understanding of the challenges we face. At the same time, Science and technology are playing an increasingly important role in a complex geopolitical landscape. In this difficult setting, scientific collaboration can not only be used to help address global challenges but also to foster international relations and build bridges across geopolitical divisions. Science diplomacy is a broad term used both to describe the various roles that science and researchers play in bridging geopolitical gaps and finding solutions to international issues, and also the study of how science intertwines with diplomacy in pursuing these goals.

During this Short Course, science diplomacy experts will introduce key science diplomacy concepts and outline the skills that are required to effectively engage in science diplomacy. They will also provide practical insights on how researchers can actively participate in science diplomacy, explore real-life examples of science diplomacy, and highlight resources where participants can learn more about science diplomacy moving forward.

Here are some of my take-aways from this course:

• Science and diplomacy are intricitely linked in that one informs the other and one is needed for the other and this goes both ways in each case
• The rise of populism and authoriatarianism are changing the landscape
• Geoscience has a lot of touchpoints with diplomacy
• Quote (Maria Leptin): "We don't ask our researchers to be diplomats - yet their excellent science naturally feeds into global policy."
• Nations retreat from multilateralism
• Nations put up barriers to international scientific collaboration
• Some challenge evidence-informed policymaking
• Scientific endeavours like turning a wetland into a protected area can have diplomatic implications if the water comes from across the border or if too much water is used for agriculture
• Right now, scientific spending often has to compete with defense spending
• Some institutions may be tempted to accept defense funding for "dual use" research
• Such "dual use research" could however make an institution's campus a military target in case of war

After the afternoon coffee-break it was time for a fun but most likely challenging session for the authors: EOS1.6 - Up-Goer Five Challenge: Making Big Ideas Simpler by Talking About Them in Words We Use a Lot. The session was held in one the underground PICO sessions and unfortunately, the Zoom-sessions wasn't completely stable, so I didn't always get the full presentation.

Whether you thrill at the chance to tell taxi drivers and dinner-table companions about your research or want to hide every time someone asks, “What do you do?”, we offer an exciting and valuable challenge for you.

Inspired by the XKCD comic that describes the Saturn V Rocket using only the thousand most common words in English (https://xkcd.com/1133/), we ask speakers to present short (~5-minute) scientific talks using the same vocabulary (determined via the Up-Goer Five Text Editor: https://splasho.com/upgoer5). The talk is preferably about your own research but can also be about a general topic you are interested in. 

Here are some examples for Up-Goer-Five lingo - can you guess what they describe (solutions below the image)?

1. people-flying things
2. sky water
3. space eye in the sky
4. black underground burn stuff
5. computer pictures
6. middle water
7. cold part of the world with water

Solutions:

1. people-flying things = airplanes
2. sky water = rain
3. space eye in the sky = satellite
4. black underground burn stuff = coal & oil
5. computer pictures = models
6. middle water = Mediterranean Sea
7. cold part of the world with water = Arctic

EGU Today

My day started with Union Symposium  US6 - Climate change, morals, values and policies, convened by Noel Baker, Chloe Hill, Mario Scharfbillig, Emmanuel Salmon and Maria Vittoria Gargiulo:

The climate challenge is no longer only about understanding the Earth system, it is also about understanding ourselves as humans. As a global society, response to climate change information and climate action policies is shaped not only by scientific evidence, but also by moral values, cultural identities, religious beliefs, fears, and psychological dynamics. Attitudes that may appear irrational often reflect deeper questions of meaning, trust, and social belonging. How can scientists and governments communicate climate science in ways that resonate with diverse societies without resorting to manipulative tactics? How can decision-makers design ethical and inclusive policies that inspire meaningful action at individual, community, and societal levels?

This Union Symposium will bring together experts from multiple disciplines to explore these questions through both scientific research and practical experience. Speakers will examine the moral, psychological, cultural, and social dimensions that shape public engagement with climate change. Perspectives from religious traditions, as well as indigenous and marginalized communities, will broaden the dialogue and offer insights into how climate communication and policy can become more inclusive, trustworthy, and impactful.

The symposium started with an introduction by Dr. Mario Scharfbillig, who uses behavioural insights to improve evidence-informed policymaking and democratic processes in the EU. He first noted that there is broad global support for climate action but that this is not really well-known due to a perception gap leading people to consistently underestimate the willingness of others to act. This also holds true for politicians and there own voters.

People have different priorities dependent on whether the focus is on higher order values, personal values, values terminology, social identities or the big picture. People live in different worlds which can be caused by and/or lead to information overload, distorted reality, echo chambers or even echo platforms and a "fantasy-industrial complex".

After this introduction, each panelist gave a 10-minute keynote to "set the stage" for the subsequent discussion.

Raffaella Russo is an economist and project manager working at the science-policy intcrface, focusing on the socio-cconomic impacts of climate risks, risk perception, and adaptation strategies. She is a member Of EGIYs Climate Hazards and Risks Task Force. 

She started with a quote from the European Environement Agency: "Climate change is already impacting Europeans' daily lives and will continue to do for the foreseeable future. Europe is expected to get warmer, some regions getting drier, while others wetter. These changes will not only impact our health bu also the ecosystems we depend on. The EU is preparing to live with a changing climate through various adaptation measures."

She then gave a few examples illustrating the transition from isolated shocks to recurring and compoundng events happening in Italy just between 2023 and 2025. She pointed out that - while funding from the country and EU was allocated after the 2023 Emilia Romagne flooding - there is a need to strengthen  the private sector involvement in climate adaptation programming. In addition, fragmentation has to be replaced by coordination in order to reach a whole-of-society approach to climate resilience.

Eli Mitchell-Larson is a climate advocate, policy entrepreneur, and Ph.D. researcher based at the University of Oxford. Eli currently advises the Climate Pathfinders Foundation, facilitating grants to advance carbon dioxide removal and next-generation climate interventions. He previously co-founded and served as Launch Director and Chief Scientist at Carbon Gap, Europe's leading NGO dedicated to responsibly scaling carbon dioxide removal. 

He laid out five hypothesis related to climate advocacy [I updated the list after watching the recording]:

1. For geoscientists there are no neutral choices. Every choice we make is politically relevant.
2. Climate policy-advocacy is not a monolith, it can be behind the scenes, it can be slow, it can be measured, it can be injecting expertise where needed.
3. Engaging with climate policy is not as challenging or isolating as a lot of researchers may fear.
4. Engaging with climate policy makes you a better scientist.
5. Geoscientists are uniquely suited to be climate policy advocates.

Dr. Gabriel Filippelli is the Chancellor's Professor, Director of the Center for Urban Health, Executive Directorr Environmental Resilience Institute at Indiana University in the United States. He started his keynote with an image of the Keeling Curve which is a "5-alarm fire" for scientists but doesn't really mean much for people you might meet in a train or on the street.

Individuals care about concrete instead of abstract things (e.g. fuel prices vs. polar bears) and there's therefore a need to change the message. Compare "things" like energy infrastructure on equal footing and with concrete numbers, so for example point out the noise and pollution caused by an oil refinery to that of a solar farm. You may also need to change the messenger. So, instead of having a climate scientist talk with a local community, train students to become "Climate Fellows" who can then work towards making their neighbourhood climate resilient. This also provides an opportunity for the students, many of whom later work in sustainability and environmental careers.

 

Emelina Corrales Cordero is a Costa Rican marine biologist, environmental consultant, and executive coach With over 20 years of experience in marine conservation and climate action. She integrates science, mindfulness—rooted in the Plum Village tradition— and leadership to support leaders navigating eco-anxiety while sustaining purposeful action. She is the co-creator of Politics of Being, author of Grandmother Ocean Speaks, and was awarded the French Senate Medal of Honor in 2025. 

After a short meditation exercise, Emelina introduced us to "The Mediator, The Warrior and The Artist" to help with navigating geological and biological timescales. She started her keynote with a quote from Christine Wamsler et al. (2019): "Transformative change toward sustainability depends on changes in inner dimension such as: beliefs, values and worldviews.". This was followed by a quote from Zen master Thich Nhat Hahn: "There are two dimensions to life, and we shall be able to touch both. One is like a wave and we call it the historical dimension. The other is like water and we call it the ultimate dimension." 

Emelina Corrales ended her keynote with reciting her poem "All Waters: The Ocean of Life" which you can read on her website.

After these diverse keynotes, the discussion was opened to questions from the audienence and many participants made good use of this opportunity. It was tricky to capture all the questions and answers, so here are just a few notes:

• How can those who protect the environment be better protected? Response was along the lines of making their voices heard, don't visit countries where activists are getting persecuted or even killed.
• Focus on dialog instead of persuation
• Ask people questions and really listen to their replies.
• What ONE advice should high school teachers give their students?
• Take care of what you do in every day life.
• Get involved and vote!
• Take them outside
• Put down the phone!

The session was recorded and if/when the video is made publicly available on Youtube, I'll add the link here. In the meantime, this compilation gives an idea of what all was covered in this symposia: 

After the lunch break I had planned to join short course  SC3.13 - Get your writing right: A hands-on, participatory workshop to help improve writing skills, but it turned out that this was only available onsite in Vienna, so I couldn't join it virtually. Poking around in the program for an alternative, I noticed one of the science sessions and joined ITS2.1/CL0.7 - Compound weather and climate events instead.

High-impact climate and weather events typically result from the interaction of multiple climate and weather drivers, as well as vulnerability and exposure, across various spatial and temporal scales. Such compound events often cause more severe socio-economic impacts than single-hazard events, rendering traditional univariate extreme event analyses and risk assessment techniques insufficient. It is, therefore, crucial to develop new methodologies that account for the possible interaction of multiple physical and societal drivers when analyzing high-impact events under present and future conditions. This session aims to address several challenges and topics.

These include: (1) identifying the compounding drivers, including physical drivers (e.g., modes of variability) and/or drivers of vulnerability and exposure, of the most impactful events; (2) Developing methods to better shape the definition and classification of compound events, i.e. legitimate the ‘cut-offs’ in the considered number of hazard types or variables to ultimately disentangle enough information for decision-making; (3) Understanding whether and how often novel compound events, including record-shattering events, will emerge in the future; (4) Explicitly addressing and communicating uncertainties in present-day and future assessments (e.g., via climate storylines/scenarios); (5) Disentangling the contribution of climate change in recently observed events and future projections (attribution); (6) Employing novel Single Model Initial-condition Large Ensemble simulations, which provide hundreds to thousands of years of plausible weather, to better study compound events. (7) Developing novel statistical methods (e.g., machine learning, artificial intelligence, and climate model emulators) for studying compound events; (8) Assessing the weather forecast skill for compound events at different temporal scales; (9) Evaluating the performance of novel statistical methods, climate and impact models, in representing compound events and developing novel methods for constraining/reducing uncertainties (e.g., multivariate bias correction and observational constraints); and (10) engaging with stakeholders to ensure the relevance of the aforementioned analyses.

From the description this seemed to be a scientific session which didn't require too much prior knowledge and this turned out to be true. Sonia Seneviratne introduced the topic with a longer than usual presentation for these oral sessions to explain what the purpose and main focus was. Compound extreme events happen when for example a flood event follows quickly after a drought event, or when several of these events happen close after or to each other, limiting resources for help and clean-up activities. These events can come with high costs in both lives lost and money.

The authors for example talked about a need to adapt to larger scale drought and to ensure that water is still available where and when it is needed, about the risks extreme humid heatwaves pose for human health, wether there are detectable trends in soil moisture, how marine and terrestrial heatwaves are connected, that marine heatwaves are happening more frequently, are getting more intense and last longer, that heatwaves often coincide with river-low-flows (less water flowing downstream), that rivers can get too warm for cooling nuclear power plants, that low-flow events have from the local to a European scale and that climate extremes like heatwaves and extreme floods are happening with less time in between in Pakistan.

As my last session for the day I joined PICO EOS1.3 - Games for Geoscience showcasing many creative ways of how to turn science into fun and interesting learning experiences. The session was convened by Christopher Skinner, Rolf Hut, Elizabeth Lewis, Lisa Gallagher and Maria Elena Orduna Alegria. As is typical for a PICO session, presenters only had 2 minutes for their pitch during the first part of the session and afterwards moved to their individual screens for more detailed discussions.

Games have the power to ignite imaginations and place you in someone else’s shoes or situation, often forcing you into making decisions from perspectives other than your own. This makes them powerful tools for communication, through use in outreach, disseminating research, in education and teaching at all levels, and as a method to train the public, practitioners, and decision-makers in order to build environmental resilience.

Games can also inspire innovative and fun approaches to learning. Gamification and game-based approaches add an extra spark of engagement and interaction with a topic. Gaming technology (e.g. virtual reality) can transport and immerse people into new worlds providing fascinating and otherwise impossible experiences for learners.

The 2-minute pitches covered all sorts of games: card games, board games, role plays, simulations, planning games, escape games and digital games. They also touched many topical areas like natural hazards (think: mud slides or earth quakes), resource management (think: aquifers in danger of drying up), climate resilient planning, policy simulations, geothermal energy, saving oceans, climate change and mitigation and more!

EGU Today

As the first session I joined short course SC3.2 - Instruments and Initiatives for Policy Engagement convened by Erika von Schneidemesser, Zsanett Greta Papp, Chloe Hill and Alice Albertini

Are you keen to see your research results integrated into decision-making but don’t know where to start? Science for policy can be very rewarding, but some basic considerations for engaging in science-policy can help you get your foot in the door or up your level of impact. A basic introduction that provides some tips for engagement will be followed up with short impulse talks from a panel of experts, highlighting different opportunities for policy engagement and the skills that got them there. It will also include teasers for different existing toolkits (e.g., Sci-4-Pol Competence Framework) and training opportunities (e.g., Science-Policy Pairing Scheme, or IEEP-EGU mentorship scheme) to boost your science for policy engagement skills. The session will end with an open Q&A with the panel.

This short course started with Zsanett Greta Papp giving us an overview of what all EGU offers for scientists who might want to get into the wide field of Science for Policy. Detailed information is available in this EGU blog post from 2024: GeoPolicy: 10 things that you can do to start engaging with policymaking today and this flyer lists them all:

Florian Schwendinger then told us about his experiences with working in the field of Science for Policy. He mentioned that you need quite a lot of different competencies and that you have to be prepared for "information overload" because you'll need to collect it, sift through it and then interpret and summarize it for the policy maker you are working with. You need to be aware of the policy implications the information has and understand the context and different timelines you are working in. You need to invest time in order to build trust, you need to understand available support structures and the different attitudes involved. And most important of all: don't fall for the myth that policy makers are bound to ignore scientific findings! If you manage to make information accessible and legible for them, chances are good that they'll take it into account.

Next Nicole Arbour enthusiastically (and without slides) told us about non-traditional was to engage in Science for Policy. One of the first things she mentioned was that soft skills - contrary to what some believe - are very important in this area where science and policy overlap and interact. Active listening is especially relevant as is building a network by meeting as many people at receptions as possible (even if that is not your favorite kind of event). She for example regularly organizes what she called "Science parties" where she brings in a scientist prepared to give a 15-minute keynote - without scientifc charts or error bars - for invited policy makers. In addition, she encouraged scientists to write op-eds (you never know who reads those, but they can have a direct impact on policy), go on podcasts, join advisory boards and accept expert roles.

As the last speaker of this short course Alice Albertine explained the new mentoring program set up by EGU and the Institute for European Environment Policy (IEEP) of which she was the first mentee. This mentoring scheme is a 12-month flexible, hybrid programme for early and mid-career researchers who have completed a PhD. The objectives are to gain experience in a non-academic sector, broaden the mentee’s professional network, develop/increase an understanding of the European policy landscape, enhance their science for policy skills, and learn about how they and their institutions can increase the policy impact of their research. Activities include contributing to existing IEEP projects and publications, attend IEEP events and networking. Alice pointed out the human factor is very important and that helps to engage with many teams even those not directly linked to your project.

After the coffee break it was time for short course SC3.3 - New Toolkits – the destabilisation of science and what we can do about it convened by  Lene Topp, Zsanett Greta Papp, Erika von Schneidemesser and Chloe Hill:

Science is increasingly under pressure from political polarisation, misinformation, and declining public trust. These dynamics not only destabilise scientific communication but also challenge the ability of researchers to engage effectively with society and policymakers. To navigate this landscape, scientists and science communicators are developing new “toolkits” – practical methods, frameworks, and strategies – that support resilience, credibility, and impact.

This short course will introduce participants to a set of emerging toolkits designed over the coming year, focusing on how researchers can strengthen the role of science in public discourse and policy. The session will explore key questions: How can scientists better anticipate and counter misinformation? Which communication strategies foster trust across diverse audiences? What can we learn from cross-disciplinary and international experiences in addressing science denial and disinformation campaigns?

The invited speakers gave short keynotes to set the stage for the course:

Sheena Cruickshank is a science communicator, immunologist, and Professor in Biomedical Sciences and Public Engagement at the University of Manchester. During the COVID-pandemic she learned a lot about how important it is to communicate science effectively and to build trust with communities you work with. She trained communicators from communities of how to translate scientific jargon and to give them the necessary vocabulary and toolkits. She also stressed the importance of what she called the "Five C's":

• Confidence and trust in the people making vaccines, the science, etc
• Complacency considers whether people feel complacent regarding risks of infection vs vaccine
• Convenience is how easy is it to get vaccinated
• Communication is about how clear the communication is and if it is in the right language and accessible
• Context considers cultural contexts and barriers like e.g. whether there is historical mistrust in a group

George N. Georgarakis is the Moritz Schlick Postdoctoral Fellow in Digital Political Communication in the Department of Communication at the University of Vienna. Together with a team he conducted research into how misinformation spreads online and what options exist to decrease sharing of false information and increase the sharing of true content. They found that a lot of misinformation is shared by actual people and not by bots, that political motivation, heuristics (mental shortcuts) and accuracy neglect are some of the reasons for this.

He mentioned various forms of interventions like debunking, pre-bunking and credibility lables, or asking people actively to not share false information. They found that the interventions didn't increase polarization with results replicated in several countries already.

Matthias Fejes is the Co-founder of Scicomm-Support, TUD Dresden University of Technology spokesperson, and member of the executive board of the German Association for University Communication. He introduced participants to the Scicomm-Support platform which is a central point of contact for scientists if they get attacked or harrassed. He explained the four different dimensions of hostility towards science, namely anti-science, ingorance about science, science skeptisim and denial of science. 

He gave some pointers of how to recognize the situation (what it is, whether or not it's dynamic, what happened, who should be contacted), what the context of the situation is (social media posts, threads via phone, email or letters), which information can be found online about you, what are the options (refute, confront, ignore, criminal prosecution).

The subsequent discussion touched on topics like necessary smarter regulation of platforms; they may need to be forced to bring fact-checking back. Everybody needs to be mindful of self-care and resilience. The course ended with some tips for attacked or harrassed scientists:

• whenever available get prevention training
• be aware about how sensitive your research topic is
• draw on the academic community for support
• report incidents to police
• but pick your battles and make use of the block option online

 

After lunch, another short course was on the menu: SC3.10 - Elevate your Pitch: Developing Engaging Short Scientific Presentations convened by Antara Dasgupta, Hannah Cloke, Hazel Gibson and Simon Clark. This was a neat mixture of input from the conveners and a practical exercises for 1-minutes pitches with getting feedback on.

The scientific communication landscape in the digital era is rapidly becoming all about effectively delivering ideas in brief. As scientific conferences move from longer physical meetings to more condensed hybrid formats, not only are short presentations necessary for pitching yourself to senior scientists or your next entrepreneurial venture to Venture Capitalists, but also for promoting your research. The opportunities of networking rarely reveal themselves, unless you are able to tell a brief, informative, and compelling story about you and your research.

It is truly an art to engage people through these short presentations and ignite a fire in their hearts, which will burn long enough for them to remember you and reach out to you later about relevant opportunities. While practice makes perfect is the mantra for delivering power-packed short presentations, there are several tricks to make your content stand out and set yourself apart from the crowd.

In this hybrid format course, we will bring together ideas and tips from years of sci-comm experience to provide you a one stop shop with the tricks of the trade. Finally, a hands-on exercise where participants will receive structured feedback on all aspects of their talk will help solidify the learning outcomes. 

In the first part of the session, Antara Dasgupta walked us through some tips about succesful presenting: 

• Ground yourself before giving a talk (try a "power pose" like "The Cormorant")
• Concentrate on a good pitch: clarity, conficence, delivery
• Simple story-telling is a key to a killer pitch, so channel your inner story teller
• Know your audience
• Record yourself for effective practicing
• Own your mistakes (everybody makes them!)
• Identify your stumbling blocks, words you have problems with and if need be replace them
• Be careful with jargon and acronyms - even fellow scientists may not know what they mean if they work in a different field
• Talk to the audience not the floor or screen
• Be careful with reading from a script as veering off from it, may trip you up

This theoretical section was then followed by an exercise where on-site participants split into pairs to prepare and practice a 1-minute pitch. Online participants were encouraged to do this as well, albeit on their own. Volunteers had a chance to give their pitches in the room after about 20 minutes preparation and some did. So, we heard from a meteorologist who keeps the planet safe by forecasting "space weather" or about how wind turbines "feel" about their job and a few more.

I used the opportunity for a quick pitch about the Cranky Uncle game, recycling parts from a PICO-session I gave in 2022. Based on the reactions from the room - I did hear some chuckling at the expected places - and the feedback provided, it came across quite well.

I'd like to briefly introduce you to Cranky Uncle, a critical thinking game developed by John Cook to build resilience against climate and other misinformation.

The game helps you to understand Cranky Uncles by becoming a Cranky Uncle yourself.

And you learn the techniques of science denial which are: fake experts, logical fallacies, impossible expectations, cherry picking and conspiracy theories.
All easily memorable via the abbreviation FLICC.

Cranky Uncle mentors you on how to deny science by using these FLICC techniques.

You then practice spotting these techniques with the help of cartoon quizzes and other forms of quiz questions.

As you move along you build up Cranky points.

And the more cranky points you get, the more you are able to level up and see your mood get ever crankier.

To wrap up the day I joined Great Debate GDB3 -  Geoengineering - Overarching Great Debate convened by Marie G. P. Cavitte, Zsanett Greta Papp, Noel Baker and Erika von Schneidemesser:

As our world approaches 1.5°C of global warming, as worldwide emissions continue to grow, and the impacts of climate change escalate, there is a general sentiment that we are running out of time. Increasingly, geoengineering concepts are being pushed into the media and policy spheres, using this sentiment of urgency to frame these concepts as “buying us time” for mitigation. There are many concepts, with the most advanced concepts including solar radiation management (marine cloud brightening, stratospheric aerosol injection mostly), sea ice thickening/brightening, sea curtains, tarping mountain glaciers, ocean fertilisation or alkalinity enhancement, as well as ocean biomass dumping, and many more. Some might target the root cause of our rising temperatures by absorbing carbon dioxide from the atmosphere, but with detrimental effects on the ecosystems impacted. Other concepts would just attenuate the symptoms of our planet, the rising global temperature.

Are geoengineering concepts a distraction from our urgent need for adaptation and mitigation? In a world where research funding, political focus on the green transition, and geopolitical order are dwindling, are we reducing our chances of reaching the highest possible mitigation ambition to stay well below 2°C and pursue efforts to stay below 1.5°C by even discussing these options? Several of the targeted ecosystems (e.g. our deep ocean, cloud-aerosol interactions, etc.) are not yet well understood at a fundamental level. Is it appropriate to advocate for their manipulation without first conducting adequate fundamental research?

Not too surprisingly given the topic, this turned out to be a very interesting and timely session, for which the focus had been restricted to two kinds of geo-engineering: solar radiation management (SRM) and Marine carbon dioxide removal (mCDR). The debate started with 10 minute keynotes from the panelists. The information provided below is based on my notes and the slides presented:

Carl Friedrich Schleussner leads the Integrated Climate Impacts Research Group at IIASA, and is also an Honorary Professor at Humboldt University Berlin. His research spans extreme climate events, climate impact projection, tipping elements and the societal implications of climate change, with a special focus on international climate negotiations and climate overshoot.

Carl Schleussner expects that carbon dioxide removal (CDR) will become necessary in one form or the other to compensate for the very likely overshoot our continuing emissions are causing. He noted that there'll be side effects and unitended consequences and that SRM obviously doesn't fix the root cause of the problem. He also mentioned that there is no defined governance at the moment and that it could be used for geopolitical leverage and cause conflicts.

Yolanda López-Maldonado is a Maya Indigenous Earth systems scientist advancing Indigenous science in global environmental governance. Lead author of the upcoming UNEP Global Environment Outlook Report, a Review Editor for the 2nd IPBEST Global Assessment, and the founder of Indigenous Science, an Indigenous-led organization dedicated to integrating Indigenous knowledge into global scientific and diplomatic frameworks. Yolanda bridges Indigenous knowledge and global policy at the highest levels.

Yolanda López described SRM as a hypothesis about climate interventation but not a proven solution. Indigenous people nned to be involved and heard as right-holders instead of just stake-holders (if even that). Any intervention that alters the Earth system should be evaluated with a multidecadal perspective that Indigenous knowledge often provides. A globally inclusive, transparent and equitable scientific assessment process for SRM is required (UNEP 2023). Ethically, Indigenous peoples must be involved because they have a legitimate right to participate in decisions that may affect their territories and futures. If SRM is ever considered seriously, it must be governed as a planetary issue, not a technocratic fix: scientifically uncertain, ethically consequential, and inseparable from justice, Indigenous rights, and long-term observation.

Philippe Tulkens is head of the unit “Climate and Planetary Boundaries” in the Healthy Planet Directorate in DG Research and Innovation at the European Commission. His unit co-programs EU R&I activities in the areas of climate change, biodiversity, nature-based solutions and environmental observation. His unit is the EU focal point to the IPCC and EU co-focal point to the IPBES. Philippe is also the Deputy Mission Manager for the EU Mission on Adaptation to Climate Change.

Philippe Turkens stated that from an EU perspective SRM is seen as a risk and is poorly understood. A commitment to assess the risks and uncertainties, to promote international discussions which are guided by the precautionary principle is needed and a moratorium on deployment is called for.

Sian Henley is a Reader in Marine Science and Deputy Head of the Global Change Research Institute at the University of Edinburgh. Her research spans climate and environmental change in the polar oceans, both the Arctic and Antarctic, to climate change impacts on children worldwide. Sian is active at the science-policy interface with a focus on Earth’s polar regions, such as at the COPs and the UN Ocean Conferences. 

Sian Henley focused on the mCDR options and none of the proposed ideas really passes scrutiny. Even if they are tried, they will most likely not have much of an impact and these thought experiments should not distract from the urgen task to decrease emissions as quickly as possible. Of the proposed options, only iron fertilization has been tried experimentally but the results were not conclusive. There is however a risk that ocean chemistry would be changed with the nature of these changes being unknown. Impacts on fisheries and therefore people in the global south could be high, so they would be the ones most affected by decisions made in the global north - possibly even without their involvement.

Wil Burns serves as the Founding Co-Director of the Institute for Responsible Carbon Removal, a research center at American University in Washington DC, and is a Professor in the School of International Service. His research focuses on the law and governance of carbon dioxide removal and solar radiation modification approaches.

Wil Burns touched on some of the same issues Sian Henley mentioned and also pointed out that decarbonization of industry has to be tackled aggressively. He still fears that some carbon removal will be needed, something the IPCC expects as well. 

A lot more points were raised in the subsequent panel discussion and during the Q&A part, here are some of them:

• no governance framework exists for CDR and it doesn't fit into any of the existing climate-related frameworks
• 77 countries include CDR in their Nationally Determined Contributions (NDCs) without giving any details
• geo-engineering is complex and therefore hard to explain to policy makers
• community led and nature based solutions may be better options
• topic is sensitive
• there's no transparency of who and why is currently pushing for geo-engineering
• how to avoid falling into the trap of "technical fixes"?
• some want to deploy e.g. SRM quickly because the situation is so dire
• some say that mitigation and adaptation needs to speed up first
• CDR could be abused for coercion
• we could be opening a Pandora's box
• large-scale testing will most likely happen - w/o asking - on indigenous land or near disenfranchised communities
• how big is the risk of somebody going roque and "simply" start something? Would we even be able to detect it?

So, at the end of the debate there were perhaps more open than closed questions but it definitely was thought-provoking!

EGU Today

I started the last day of virtual EGU with another PICO-session: NH9.13 - Innovative Approaches to Hazards, Risk and Disaster Education and Communication convened by Bruce D. Malamud, Thomas Glade, Annika Fröwis, Faith Taylor, Caroline Michellier and Solmaz Mohadjer:

Resilience building requires effective communication, teaching and understanding of hazard and risk. Traditional outreach methods often struggle to engage diverse audiences; connect science and practice; or influence policy. Innovative approaches can address some of these challenges. For example, digital tools such as serious games, (massive) open online courses (MOOCs), simulations and immersive virtual/augmented reality can bring hazard scenarios to life. Equally, non-digital methods such as role-play, participatory mapping, classroom activities and tabletop demonstrations can foster engagement and deeper understanding of risk. This session welcomes abstracts that explore the development, application and evaluation of education and communication innovations across a spectrum: from primary through the postgraduate learning, and from public to expert engagement. We particularly welcome contributions of serious games, VR/AR simulations and digital platforms in addition to non-digital methods such as classroom demonstrations and participatory activities. Presentations that reflect on co-production with stakeholders, inclusivity and approaches for evaluating outcomes are strongly encouraged. In this session, we hope to bring together researchers, educators and practitioners to share best practice, showcase cutting-edge tools and teaching methods, and critically reflect on the role of innovation in hazard and risk education and communication. We plan on having a PICO session to ensure a lively combination of discussion and poster presentation. 

The conveners had divided this 2-part PICO-session thematically. Before the morning coffee-break we heard about serious games & simulations and academic & professional eduction projects. Afterwards the themes changed to child & youth eduction, public engagement and media. Unfortunately, some of the speakers didn't make it in time to the session because there were issues with public transport in Vienna.

Initially, I wasn't quite sure if a session from the Natural Hazards (NH) science section of EGU would make much sense for me to join as I usually gravitate towards the education, outreach and policy sessions offered at the conference. However - and after taking a closer look at the submitted abstracts - this could just as well have been an EOS-session given that the talks were in fact about different education and outreach strategies in the realm of natural hazards.

As this was a PICO-session, short 2-minute pitches followed in rapid succession during the first part of each timeblock. We heard about an online simulation game where players have to evacuate people after an earthquake without getting into landslides while doing so, about gamified flood resilience simulation and effective risk communication, about underappreciated hazards of burning lowlands, about disaster risk reduction in case of floods and wildfires, about necessary civic engangement when it comes to natural hazards, about climate-driven geohazard mitigation, about enhancing risk management through education, research and innovation, about webplatforms collecting natural hazards, about storytelling and podcasts to get the word out.

In addition to the many different topics touched upon, where these projects are done is just as varied: they could be very local (Tübingen in Germany), regional (lowlands in The Netherlands), moutaineous areas in Nepal, Pakistan, Austria, South Korea, Japan, Norway, Sweden, Austria, Italy, volcanic regions in The Democratic Republic of Congo, on the Canary Islands or the Philippines. Or they could be in virtual and synthetic worlds simulating various places.

• Nemesio M. Pérez - The role of media and journalism in volcanic risk reduction: insights from the Canary Island 

This turned out to be the last session I documented during the week. The virtual poster session I had on my list for the afternoon turned out to contain only a few presentations from a cross-section of what had already been covered in oral sessions during the week and lasted for only 30 minutes. Some of the posters were flagged as "no pictures allowed" and some were in a format not really suitable to grab screenshots of.

Over the final lunch break of EGU26 I headed back up to the rooftop in Gather on the off-chance that somebody might come there for the last networking session I had offered to chat about Skeptical Science. While nobody came for the session itself I had a nice - if short - chat with another participant who joined EGU virtually from Australia. 

Summary

As you can tell by the length of this blog post (sorry about that!), EGU kept me pretty occupied during the week. All told, I gave 2 oral presentations, joined 14 timeslots covering 4 Education and Outreach sessions (EOS) two of which were done as oral sessions and two as PICOs, 1 Natural Hazards PICO session (NH), 1 Inter- and Transdisciplinary Studies session (ITS), 4 short courses (SC), 1 Union Symposium (US) and 1 Great Debate (GDB). Joining the sessions virtually worked pretty well and only one of the PICO-sessions did have some technical issues with the Zoom-Meeting.

During the sessions I grabbed about 500 screenshots of which 162 made it into my visual session summaries and from there into the daily compilations. I took a lot of notes on my iPad during the sessions but fear, that I won't really be able to read my own scribbles when I look at them again in a short little while. But they did help with writing my diary, so served their main purpose quite well.

Final update from the EGU-website: "The EGU General Assembly 2026 welcomed 22,497 registered attendees, of which 20,027 made their way to Vienna from 125 countries and 2,470 joined online from 107 countries. It was a great success with 20,173 presentations given in 1,014 sessions. [...]"

To paraphrase a saying: "After a General Assembly of the European Geoscience Union is before the next one"! I plan to join EGU27 onsite in Vienna next year when the conference will happen a month earlier than this year from April 4 to 9. I'm already looking forward to the trip!

Emerging low-cloud feedback and adjustment in global satellite observations, Ceppi et al., Atmospheric chemistry and physics

From mid-2003 to mid-2024, a global decrease in low-cloud amount enhanced the absorption of solar radiation by 0.22±0.07 W m−2 per decade (±1σ range), accelerating the energy imbalance trend during that period (0.44 W m−2 per decade). Through controlling factor analysis, here we show that the low-cloud trend is due to a combination of cloud feedback and adjustments to greenhouse gases and aerosols (respectively 0.09±0.02, 0.05±0.03, and 0.03±0.03 W m−2 per decade), which jointly account for 74 % of the trend. The contribution of natural climate variability is weak but uncertain (0.01±0.08 W m−2 per decade), owing to a poorly constrained trend in boundary-layer inversion strength. Importantly, the observed low-cloud radiative trend lies well within the range of values simulated by contemporary global climate models under conditions close to present day. Any systematic model error in the representation of present-day global energy imbalance trends is thus likely to originate in processes unrelated to low clouds.

When Thunderstorms Reach the Stratosphere: Why Storm Structure May Matter for Climate, Cairo, Journal of Geophysical Research Atmosphere

Deep convection that overshoots the tropopause provides one of the fastest pathways for exchanging air between the troposphere and the stratosphere. Using extensive in situ observations from the dynamics and chemistry of the summer stratosphere (DCOTSS) campaign, Shepherd et al. (2026, https://doi.org/10.1029/2025JD045514) showed how storm-scale characteristics and environmental conditions shape the magnitude, depth, and pathways of stratosphere-troposphere exchange in the midlatitudes. Their analysis indicates that storms producing above-anvil cirrus plumes, as well as large mesoscale convective systems, are associated with disproportionately strong stratospheric perturbations, particularly in water vapor. This Commentary places these results in a broader context, highlights the main conceptual advances enabled by DCOTSS, and discusses remaining uncertainties while outlining priorities for future work. In particular, it argues that the main significance of these results lies not in resolving the large-scale stratospheric water vapor budget, which remains uncertain, but in helping identify which storm classes and physical pathways are most likely to matter if such impacts are to be quantified more robustly.

Record-Breaking Marine Heatwaves Across Global Coral Reefs in 2024, Yao & Wang, Geophysical Research Letters

The record-breaking annual mean global sea surface temperature in 2024 fueled extensive marine heatwaves (MHWs) across global coral reef zones, yet their spatiotemporal characteristics have not been comprehensively quantified. Here, we show that during the 2024 warm-season, MHW total days and cumulative intensity exceeded the historical mean by more than 3 standard deviations. Widespread and persistent MHWs occurred across major coral reef regions, particularly in the Red Sea, Coral Triangle, Fiji, the Caribbean, and Brazil. Most coral biogeographic provinces experienced significant increases in the frequency of Moderate, Strong, and Severe MHW categories relative to the 1985–2024 climatology. These extreme events were associated with substantial accumulation of ocean heat content in the Indo-Pacific warm pool and tropical Atlantic following the transition from the triple-dip La Niña (2020–2023) to the 2023–2024 El Niño. Regional oceanographic conditions further modulated the intensity and drivers of warm-season MHWs in 2024.

Beyond post-truth: Projecting the future trajectory of climate misinformation, Rice, PLOS Climate

Climate misinformation represents one of the most significant barriers to effective climate action in the 21st century. Building upon Yotam Ophir’s comprehensive framework in Misinformation & Society, this essay examines the evolving landscape of climate misinformation and projects its future trajectory. Ophir’s interdisciplinary approach, which integrates historical, psychological, and technological perspectives, provides crucial insights into how climate misinformation operates within broader systems of information disorder. This paper extends Ophir’s arguments by examining critical dimensions of his work, including the shift from outright denial to more sophisticated delay and deflection tactics, the role of emerging technologies including artificial intelligence in amplifying misinformation spread, and the political economy of climate misinformation characterized by asymmetric epistemic relationships. Drawing on recent research, I project that climate misinformation will increasingly manifest through narratives of technological futurism and transformation, the pretense of economic crisis through environmental catastrophe, and the social implications of international weaponized uncertainty inflamed by misinformation. The essay concludes by proposing an integrated intervention framework that reviews proposed solutions including psychological inoculation, systemic media literacy, and structural reforms to digital and online platform governance. Understanding these trajectories is essential for developing resilient communication strategies that can withstand the evolving tactics of climate action obstruction.

From this week's government/NGO section:

European State of the Climate – Report 2025, Emerton et al., World Meteorological Organization and European Union, represented by the European Centre for Medium-Range Weather Forecasts

Rapid warming in Europe is reducing snow and ice cover, while dangerously high air temperatures, drought, heatwaves and record ocean temperatures are affecting regions from the Arctic to the Mediterranean. Europe, along with many other regions of the globe, is exposed to increasing impacts – from record heatwaves on land and at sea, to devastating wildfires, and continuing biodiversity loss – with consequences for societies and ecosystems across Europe.

Climate Change in Central Finland, Kühn et al., Finnish Meteorological Institute

Climate change is progressing in Finland faster than the global average, and its impacts are already clearly observable in Central Finland. The authors examines the current state of the climate in Central Finland and the Jyväskylä region, observed changes, and the projected development of the climate throughout the current century. The assessments are based on long?term observational datasets, the latest climate model simulations, and SSP emission scenarios.

PwC’s Third Annual State of Decarbonization Report, PwC

The authors draw on AI-enabled insights of millions of data points from across thousands of corporate disclosures and related documents. Many companies changed how they talk about sustainability, but not what they do about it. Commitments were persistent even as the ground shifted beneath them. Eight in ten (82%) companies held steady or accelerated the timeline they needed for achieving their ambitions. More companies are increasing ambitions (23%) compared to those decreasing (18%). Progress held, with more organizations on track to meet their targets than in prior years. 87 articles in 49 journals by 717 contributing authors

2030 Climate Action Plan, City of Boston, Environment Department, City of Boston

The plan is grounded in two core and interconnected areas of work: mitigation and resilience – which frame every strategy and action included. Mitigation efforts focus on rapidly reducing emissions from the sectors that contribute most to Boston’s carbon footprint, particularly buildings, transportation, and energy. Resilience strategies are designed to protect people, infrastructure including new, existing, and historic assets, open space, and neighborhoods from the growing impacts of climate change, while strengthening the City’s ability to adapt over time and creating pathways to good green jobs that support resilience and mitigation investments. In addition to tracking progress on mitigation and resilience, we acknowledge the broader impacts of climate work across three deeply interconnected areas: public health outcomes, climate justice, and the intersection of mitigation and resilience benefits. This approach recognizes that effective climate action must deliver healthier living and working environments, address historic inequities, and maximize co-benefits, ensuring that investments reduce emissions while also protecting communities most exposed to climate risks. Climate justice is embedded throughout the plan, recognizing that the impacts of climate change will not affect neighborhoods equally and that climate action presents an opportunity to correct past harms. Communities that have been and will be adversely affected by climate change must be prioritized in both decision-making and investment.

Where rising climate risks and insurance costs will hit hardest, Manann Donoghoe, The Brookings Institution

One concept to help understand how climate-related risks could differentially affect households across the U.S. is adaptive capacity, or the ability of a household or community to plan for and respond to the impacts of climate change. By analyzing adaptive capacity in relation to instability in the homeowners insurance market, the author identifies which regions and demographic groups that instability is likely to adversely affect. Drawing on data from the U.S. Treasury Department on homeowners insurance, the Federal Emergency Management Agency’s (FEMA) National Risk Index, and Census Bureau demographic data on wealth, race, and ethnicity, the author shows the insurance premium increases and nonrenewal rates (the proportion of policies that an insurer decides not to extend at term’s end) that different demographic groups and regions faced between 2018 and 2022.

Critical Minerals, Water Insecurity and Injustice, Nunbogu et al., United Nations University Institute for Water, Environment, and Health

The investigation finds that systemic global failures are allowing the costs of critical minerals extraction to fall disproportionately on some of the world's most vulnerable communities, while the benefits accumulate elsewhere in the form of electric vehicles (EVs), renewable energy systems, and artificial intelligence (AI) infrastructure. The authors do not question the need for clean energy systems or the digital infrastructure underpinning them. Instead, it asks who is paying for and benefitting from humanity’s progress in those areas, and finds a deeply unjust answer.

European State of the Climate – Report 2025, Emerton et al., World Meteorological Organization and European Union, represented by the European Centre for Medium-Range Weather Forecasts

Rapid warming in Europe is reducing snow and ice cover, while dangerously high air temperatures, drought, heatwaves and record ocean temperatures are affecting regions from the Arctic to the Mediterranean. Europe, along with many other regions of the globe, is exposed to increasing impacts – from record heatwaves on land and at sea, to devastating wildfires, and continuing biodiversity loss – with consequences for societies and ecosystems across Europe.

Climate Change in Central Finland, Kühn et al., Finnish Meteorological Institute

Climate change is progressing in Finland faster than the global average, and its impacts are already clearly observable in Central Finland. The authors examines the current state of the climate in Central Finland and the Jyväskylä region, observed changes, and the projected development of the climate throughout the current century. The assessments are based on long?term observational datasets, the latest climate model simulations, and SSP emission scenarios.

PwC’s Third Annual State of Decarbonization Report, PwC

The authors draw on AI-enabled insights of millions of data points from across thousands of corporate disclosures and related documents. Many companies changed how they talk about sustainability, but not what they do about it. Commitments were persistent even as the ground shifted beneath them. Eight in ten (82%) companies held steady or accelerated the timeline they needed for achieving their ambitions. More companies are increasing ambitions (23%) compared to those decreasing (18%). Progress held, with more organizations on track to meet their targets than in prior years.

France's Roadmap for Transitioning Away from Fossil Fuels, Climate Interminsterial Team, Government of France

Since 2017, France has committed to a gradual phase-out of fossil fuels, mobilizing a broad range of ecological planning tools. The 2017 Climate Plan introduced a legislation to phase out hydrocarbon production in France by 2040, notably by ending the granting of new exploration permits and by not renewing existing exploitation concessions. This plan has also led to a significant reduction in fossil fuel consumption in buildings which fell by 42% between 2017 and 2022. It further aimed at accelerate the electrification of the transport sector in order to reduce its dependence on oil, by setting a end-of-sale target for thermal passenger vehicles by 2040. France will also address five environmental challenges including mitigation of global warming, adaptation to the inevitable consequences of climate change, preservation and restoration of biodiversity, conservation of resources, and reduction of pollution that impacts health.

How import rules can cut global methane emissions, Anna Kanduth and Claudio Forner, Climate Analytics

Methane is one of the quickest levers available to slow warming in the near term, yet current policies are nowhere near enough to deliver the cuts needed by 2030. As governments look for ways to narrow that gap, methane import standards are emerging as a powerful new tool. This briefing explores how the European Union’s new rules for imported oil, gas, and coal could drive emissions cuts far beyond its borders – and how, if other major importers follow, they could help close more than 40% of the gap to a 1.5°C-consistent methane pathway. At current trade levels, an EU standard of 0.2% methane intensity could reduce emissions by more than 3 Mt CH? annually from its imports alone. Wider adoption by six other major importers could cut global methane emissions by over 10 Mt CH?, driven in particular by Russia and the United States, which have the largest excess methane emissions relative to a 0.2% intensity standard.

Water Supply Systems, Fire, and Finance: A Workshop Synthesis Report, Pierce et al., UCLA Luskin Center for Innovation

A new UCLA-led convening highlights how wildfire risk could reshape water system planning and finance. Water systems were designed to provide drinking water and fight structure fires — not urban wildfires. Expanding system capacity to fight extreme events creates tradeoffs with water quality and affordability. Fire-related water use is often not fully paid for, straining system finances. Coordination between water and fire agencies is inconsistent and often informal. Recovery of wildfire-related costs raises equity concerns for ratepayers.

Massachusetts Carbon Dioxide Removal Study, Mittelman et al., Massachusetts Clean Energy Center

The authors build on Massachusetts’ prior planning to assess which carbon dioxide removal (CDR) pathways are most feasible and scalable in the state’s policy, economic, and natural resource context. The outcomes of this effort will inform future iterations of the state’s Clean Energy and Climate Plans (CECPs), which are the flagship climate planning documents, to provide an assessment of best practices and policy options that Massachusetts should consider when responsibly integrating CDR into its net-zero strategy. The authors describe and assess 23 CDR and storage pathways across several characteristics, analyzing their suitability for deployment and research and development (R&D) leadership in Massachusetts.

Diesel Reduction Progress II, Bledsoe et al., Pembina Institute

Clean electricity projects in remote communities grew 20 times faster between 2016 and 2026 than the previous decade, with most of this progress (about 92%) occurring between 2020 and 2025. Roughly three quarters of community-scale clean electricity projects built in remote communities are wholly or majority Indigenous-owned. Altogether, remote communities have added more than 65 megawatts (MW) of clean electricity capacity over the past decade, and now produce over 126 GWh clean energy annually, with 35% from wind, 33% from hydro, and 30% from solar. Remote renewable electricity generating projects have reduced annual diesel consumption by more than 31 million liters, and now account for 7% of total electricity supply in remote communities. Since 2016 these projects have displaced over 142 million liters of diesel, more diesel than all three territories use to generate electricity in an entire year.

Credit Where Credit is Due. Strengthening carbon markets to protect Ontario steel and mobilize low-carbon investment, Chloe McElhone and Richard Mullin, Clean Prosperity

In order to protect Ontario’s steel sector and signal to other industries that Ontario is open for business, the authors recommend strengthening Ontario’s carbon market in the following ways; recognize real emissions reductions from fuel-switching investments in the steel sector; award carbon credits to clearly signal that the Ontario carbon market recognizes and values real emissions reductions achieved through low-carbon investments; support predictable and stable credit values by redistributing credit revenues among all regulated emitters and opening the market to third-party investors; and publish market data frequently and create a centralized marketplace to build investor confidence and incentivize investment.

2026 State of the Water Industry, American Water Works Association

The industry survey respondents reveal a sector facing growing pressure across infrastructure, financing, and long-term water supply reliability. While overall sector health remains stable, the five-year outlook has declined to its lowest level in nearly a decade, signaling growing concern about the future. Aging infrastructure remains the most pressing challenge, closely followed by the need for sustainable funding and long-term water supply reliability. Many utilities are struggling to fully recover costs through rates and fees, creating a widening gap between revenues and rising expenses. External pressures, including economic uncertainty, political dynamics, natural hazards, and supply chain disruptions, are compounding these financial challenges and complicating long-term planning.

Oil Fund Vote Watch: Climate 2025. Norges Bank Investment Management (NBIM) voting at fossil fuel AGMs, Lucy Brooks, Framtiden i våre hender / Future in Our Hands

The author evaluates Norges Bank Investment Management's (NBIM) 2025 active ownership activities at 12 priority portfolio companies. These firms were selected because they are the world’s largest investor-owned upstream oil and gas developers currently expanding production in defiance of scientific pathways to net-zero. The author examines whether NBIM used its voting power and escalation tools to signal accountability for these firms' climate failings. Despite NBIM’s stated position that "climate risk is fundamental financial risk," the fund’s actions in 2025 at these high-priority firms reveal a significant implementation gap. Of the 23 priority votes analyzed across 12 companies, NBIM signaled disapproval of management in only three instances—with just one potentially linked to climate concerns.

Stop Greed, Build Green. A Working Class Climate Agenda, Climate and Community Institute

The climate crisis is a core driver of the cost-of-living crisis and instability we see across the economy. Electricity and gas bills are the highest drivers of inflation, rent gouging and skyrocketing insurance premiums are making housing unaffordable, extreme weather is driving food prices up, and the last three summers have been the three hottest on record. And while prices go up, the quality of our health care, goods, and homes is getting worse. Amidst all of this, billionaires are becoming richer, Big Tech firms are spending trillions on energy-hungry data centers, and a majority of U.S. residents are profoundly disillusioned with the political system. A Working Class Climate Agenda would quickly relieve the cost-of-living crisis and transform the economy to stem future climate-fueled affordability crises. More importantly, it puts the majority of voters in the driver’s seat of economic and climate transformation

The Reuse Dividend: Unlocking Economic Growth from Britain's Existing Buildings, Nelson et al., Don't Waste Buildings

The authors analyzed financial incentives used across eight developed economies — including France, Germany, the United States and Ireland — and found a proven blueprint that Britain has failed to adopt. The authors recommends four complementary measures to address building reuse including levelling the value added tax playing field, tax credits or relief, such as introducing capital gains tax relief and stamp duty discounts for bringing vacant buildings back into use while meeting sustainability quality measures, creating targeted grants for struggling high streets and derelict buildings; and subsidized finance by establishing long-term low-interest loans with repayment grants for deep reuse projects through the National Wealth Fund, or a similar institution About New Research

Video description

Climate change isn't tomorrow's problem. It's devastating lives right now in every corner of the world. In this video I take a look at four experiences of climate change in different countries: air pollution in India, extreme heat's impact on the elderly in Japan, malnutrition's effects on the young in South Africa, and the mental health toll of the crisis in Brazil. These stories show how the crisis is already affecting us. And just how much we have to save if we choose to act to halt climate change.

As mentioned in the recently published prolog to EGU2026 article, I submitted an abstract to talk about the results of the experiment we ran on Skeptical Science to gauge the effectiveness of our rebuttals. This blog post is a "companion article" to that presentation in session EOS4.1 Geoethics: Linking Geoscience Knowledge, Ethical Responsibility, and Action and will go into somewhat greater details than is possible in the 8 minutes available during the oral session for my presentation about Results of the Skeptical Science experiment and impacts on relaunched website.

Introduction

Skeptical Science (SkS) is a website and non-profit science education organization with international reach founded by John Cook in 2007. Our main purpose is to debunk misconceptions and misinformation about human-caused climate change and our website features a database that currently has more than 250 rebuttals based on peer-reviewed literature. SkS has evolved from a one-person operation to a team project with volunteers from around the globe.

Why set up an experiment?

We wanted to find out how effective our rebuttals are at reducing belief in myths and how effective they are in increasing acceptance of facts. We hoped to find out if there was a need to improve our rebuttals, whether we could identify key features of effective rebuttals, learn who is interested in reading our rebuttals and even if we could measure real-world impact of them.  

Design of the experiment (1)

Users arriving via an organic Google search at an English language rebuttal were invited to participate in a short survey via a modal screen. If they provided informed consent they were shown a pre-rebuttal survey and after reading through the rebuttal and reaching its end they were shown the same survey again as the post-rebuttal part. We also tracked their start and end times to measure how much time they spent on the page. 

Design of the experiment (2)

For both the pre- and post-rebuttal survey participants were shown the same statement related to the rebuttal they accessed. They randomly either saw a fact or a myth statement. The full list of statements used in the experiment is available in Appendix A of our published paper.

Here is an example:

• Rebuttal: "How reliable are climate models"
• Fact statement: "Scientists' computer models have been successful at predicting global warming over long time periods."
• Myth statement. "Scientists' computer models are too unreliable to predict future climate."  

Participants then selected their level of (dis)agreement with either of those statements on a 6-point Likert scale from "Strongly agree" to "Strongly disagree".

Experiment by the numbers

The data analysed for our recently published paper spans the period from November 2021 to July 2025. During that time, 858,016 visitors were shown the initial invitation, 13,432 consented to participate and filled out the pre-survey. 6,261 of them also completed the post-rebuttal form. 3146 participants were shown a factual statement in the survey quiz while 3115 were shown a myth statement.

Results - incoming climate perceptions

The majority of participants came to the website already convinced about climate change with nearly half of them (46.3 %) showing either full agreement with the climate fact or full disagreement with the climate myth. We may therefore either be just "chanting to the choir" or - what we hope is the case as it's a more constructive interpretation - our content is “teaching the choir to sing” by providing resources that empower people to respond to climate misinformation. Our survey also reached a significant number of undecided or dismissive users. 

Results - change in accuracy

We also looked at the change in accuracy - the difference between the pre- and post-rebuttal surveys. And the results are a bit of a mixed bag:

The good news is that overall, the belief in myths decreased and that we saw improved climate perceptions even among "dismissive" readers, those who either agreed strongly with the myth or disagreed strongly with the fact in the pre-survey.

The not so good news is that for a small subset of visitors and specific rebuttals, percpetion actually decresased. Those who were already highly certain (strongly agreed with facts) sometimes saw a slight dip in accuracy after reading a rebuttal. Certainly, not what we had hoped to see!

A bit of a guessing game

We had decided to keep the survey short with only one question asked to maximize participation, and therefore didn't include a question to learn why participants selected one of the options. Because of that we had to play a bit of a "guessing game" to find out what might have led to the decrease in perception for some rebuttals.

We decided to look at rebuttals which had received at least 50 completed surveys and devided them into two groups of top vs bottom performing rebuttals. We then compared the Top 3 (positive shift) to the Bottom 3 (negative shift) performers:

• Top performers: Always articulated a replacement fact and frequently identified the logical fallacy used in the myth.
• Bottom performers: Failed to provide a replacement fact and only rarely explained the underlying fallacy.

What's next?

In parallel to running our experiment, we have been working on a complete relaunch of the Skeptical Science website (see related companion blog post for EOS1.1). One new feature will be the inclusion of the fallacy employed by the climate myth. The results of our experiment indicate that moving to the fact-myth-fallacy structure in our rebuttals is a pretty good idea to increase chances of a successful debunking.

Future plans

We plan to restart the experiment some time after the relaunch of the Skeptical Science website. When we do, we plan to improve the survey design based on what we learned during this first run. We will most likely also add a few targeted and potentially open-ended questions to avoid having to guess what brought people to our website or what influenced their rating.

The team setting up the experiment

The setup for the experiment was implemented by members from our volunteer team, bringing their respective experience and knowledge to the table:

• John Cook provided the research know-how and the fact/myth statements related to the rebuttals.
• Doug Bostrom setup the necessary technical underpinnings in the backend.
• Collin Maessen and Timo Lubitz did all of the needed programming and made sure that the current website worked together well with the server running the experiment.

Were the 2022 whale deaths off the US East Coast caused by offshore wind development?

The 2022 whale deaths have not been linked to offshore wind surveys or construction. Research has found no evidence of wind farms driving whale deaths, and responsibly developed wind farms avert systemic harms of fossil fuels.

Bad practices like construction during peak migration, high-speed vessels, or not monitoring whale presence can increase risk. However, established regulations such as seasonal construction limits, population monitoring, and vessel-speed rules reduce exposure. Once operating, turbine noise is significantly less disruptive than ships. 

According to the NOAA, boat collisions and fishing gear entanglement account for most whale deaths, not wind turbines.

In contrast, fossil fuel drilling and burning routinely harm marine life. Oil and gas exploration uses highly disruptive sonar, oil spills kill marine animals, and emissions acidify oceans, weakening coral and shellfish. Warming causes population-level harms to marine mammals through altered migration routes and habitat loss.

Unprecedented 2024 East Antarctic winter heatwave driven by polar vortex weakening and amplified by anthropogenic warming, Tang et al., npj Climate and Atmospheric Science

During July–August 2024, East Antarctica experienced the most intense winter heatwave in the 46-year satellite era, with regional mean surface air temperatures across Dronning Maud Land exceeding the climatological mean by more than 9°C for 17 consecutive days. To explore the physical drivers and quantify the anthropogenic contribution to this unprecedented event, we propose a multi-model, multi-method attribution framework integrating regional climate model-based storyline attribution, circulation analogues, and large-ensemble probabilistic attribution. The results show that a pronounced weakening of the stratospheric polar vortex initiated a quasi-barotropic high-pressure anomaly, which enhanced meridional heat and moisture transport and accounted for approximately 50% of the observed surface warming. Across different models and attribution methods, synthesis of the attribution results indicates that anthropogenic warming intensified the event by approximately 0.7°C and more than doubled the likelihood of such exceptional winter heatwaves in the current climate. Probabilistic attribution further indicates that, compared to a natural climate without human influence, the likelihood of such events increases from 2–3 times today to ~6 times under moderate emissions and up to 26 times under high emissions by 2100. These findings reveal how human-induced warming is transforming even the coldest regions, with implications for ice shelf stability and predictability of future Antarctic extremes.

A recent stabilization in the lengthening of the Arctic sea ice melt season into a highly variable regime, Boisvert et al., Communications Earth & Environment

The melt season length of the Arctic sea ice is an important indicator and driver of large changes occurring in the climate system. Since 1979 the melt season has lengthened by ~40 days, driven mostly by delayed freeze onset (~ 34 days) compared to earlier melt onset (~ 7 days). However, since 2010 the melt season length has stabilized (~ 108 days), showing no consistent change over the years, instead becoming highly variable (+/− 11 days), largely driven by a loss of multi-year ice in 2000–2009 and a small change in the freeze onset (~ 2 days). There is a stark difference between the decades, where the largest changes in the melt season occurred between 2000–2009 (+ 25 days) and the smallest occurred between 2010–2023 (−2 days). This leads us to believe that, while there might be some periodicity in the processes that control the decadal variations in the melt season length, anthropogenic forcing has altered the Arctic background state and led to a new Arctic melt season that is much longer with a much thinner ice pack that is more susceptible to external forcings.

Field Observations of Sea Ice Thickening by Artificial Flooding, Hammer et al., Journal of Geophysical Research Oceans

Arctic sea ice is retreating at a high rate, also due to the positive ice-albedo feedback loop: as ice melts and disappears, it reflects less sunlight, further accelerating ocean warming. One proposed way to slow the retreat is by thickening sea ice in winter, increasing its chances of surviving summer melt. This could be achieved by artificially flooding existing sea ice with seawater pumped from below, allowing it to freeze at the surface through exposure to cold air and thicken the ice layer. However, the effectiveness of this approach remains uncertain, as numerical models show contrasting results and few field experiments have been conducted. This study examines the growth and melt of ice through spring and summer after artificial flooding covering , resulting in thickened (+26 cm) snow-covered first-year sea ice. Observations were carried out in Vallunden Lagoon (Van Mijenfjord), Svalbard, from 20 March to 24 June 2024, with flooding and intensive in situ measurements from 11–15 April. Artificial flooding significantly heated the upper two-thirds of the original 90 cm thick ice, increasing salinity. Surface albedo evolution was influenced by specific events such as slush formation, snow drift, and a major meltwater drainage event in spring. Artificial flooding resulted in thicker ice and delayed rotten ice formation by 6 days, but did not delay the disappearance of ice in summer compared to a non-flooded reference site. Experiments at other scales and locations could help reveal how local conditions and flooded area size influence results and the potential of this method.

The achievability of low-emission IPCC sea-level rise scenarios, Millman et al., Philosophical Transactions of the Royal Society A Mathematical Physical and Engineering Sciences

The Intergovernmental Panel on Climate Change (IPCC) AR6 report (2021) provides a range of projections on greenhouse gas emissions and global warming, and the consequential impact on global sea level through thermal expansion of sea water and by glacier and ice-sheet mass loss. This paper assesses the likelihood of lower IPCC sea-level rise scenarios (SSP1–1.9 and SSP1–2.6) in light of current ice-sheet observations and model limitations, alongside today’s emissions trends and current shortfall of climate commitments. We conclude that ‘low-end’ projections may underestimate the true pace and magnitude of future sea-level rise and, if we continue on today’s mid-higher emissions pathway (SSP3–7.0), sea-level outcomes of more than 1 m by 2100 should be planned for. The worst can still be avoided through rapid deep emissions reductions, but it is essential that the IPCC continues to reflect these true risks for decision-makers, with rises of more than 2 m this century and several metres thereafter a real possibility.

Audience engagement with climate change content on YouTube: an analysis of video attributes and user interactions, Aharonson et al., Frontiers in Climate

Results indicate that videos presented by scientists are significantly more likely to elicit positive audience attitudes than those presented by politicians or other public figures. Solution-focused framing is strongly associated with positive engagement, while blame-oriented framing is associated with negative responses. Additionally, threaded comment discussions show a higher proportion of positive attitudes than independent comments, suggesting that conversational interaction enhances constructive engagement. These findings highlight the importance of expertise-based communication, solution-oriented narratives, and interactive discourse in digital sustainability communication. The study contributes both methodological tools and practical insights for designing climate change communication strategies that foster informed and constructive public engagement.

Trust, Media Habits, and Misperceptions Shape Public Understanding of Climate Change, Marryam Ishaq and M. Speiser, ecoAmerica

A hidden climate majority exists. Most Americans are concerned about climate change, but they do not realize how widely that concern is shared. This perception gap (pluralistic ignorance) masks a strong hidden consensus on climate concern. Trust in information and personal concern about climate change reinforce each other. Americans who trust the information they see or hear are far more likely to be concerned about climate change (79%) — and those who are climate-concerned report higher trust. This creates a reinforcing loop between trust and concern. Media ecosystems shape climate beliefs. Where Americans get their news influences what they believe about climate and energy. While mainstream national media, local news, and social media remain the most widely used sources overall, partisan and age differences shape which sources are most relied on, which in turn shapes climate beliefs. Americans trust the information they encounter but doubt others’ ability to recognize climate misinformation. While many Americans trust the information they personally consume, they are far less confident in others’ ability to distinguish climate fact from fiction — especially when they perceive others as less concerned about climate change. Mistrust of others and misperceptions are core barriers to climate action. Rather than a lack of concern, some of the biggest barriers include eroded trust and misperceptions. Misperceptions about energy sources and others’ climate beliefs, combined with low confidence in the public’s ability to navigate climate misinformation, suppress visible engagement and slow individual and collective action.

People and Climate Change, Ipsos

As temperatures rise, the individual responsibility to act has fallen. The past 11 years have been the warmest in the modern era, but people increasingly place less responsibility in needing to act. In the last five years, all countries surveyed in the report in both 2021 and 2026 have seen falls in the proportion who agree that individuals would be failing future generations by not acting against climate change. Short-term fear is countering long-term preparation. While climate concern remains present – 59% on average across 31 countries say they country should be doing more in the fight against climate change - more immediate risks are seen as greater priorities. Our What Worries the World survey finds concern about climate change in 11th place, behind more tangible, immediate worries issues like crime, unemployment, and inflation. The energy transition is at a crossroads. Public support for transitioning to clean energy is increasingly conditional, contingent on affordability, reliability, and security trade-offs. The Ipsos Energy Transition Barometer finds one in two (50% across 31 countries) support governments prioritizing low energy prices even if emissions increase.

Climate Change and Migration from Central America: Insights from Migrants in Mexico, Kerwin et al., UC Berkeley School of Law

The authors examine how climate-related harms intersect with and exacerbate violence, exclusion, discrimination, and weak state protection to drive migration from El Salvador, Guatemala, Honduras, and Nicaragua. Drawing on interviews, desk research, and surveys with people on the move in Mexico, the authors show that climate change rarely operates as a single cause of displacement. Instead, migrants consistently describe how environmental shocks—such as droughts that destroy crops, storms that damage homes and livelihoods, and deforestation and extreme heat that undermine health and economic stability—exacerbate existing insecurity and hardship. The authors focus on Mexico as both a transit and destination country for Central American migrants impacted by these dynamics. The findings demonstrate that better understanding how climate change intensifies vulnerabilities to violence, insecurity, and loss of livelihood—and integrating that analysis into refugee and immigration representation and adjudication— can improve access to protection and to regular migration status under Mexico’s existing legal framework. The authors also offer specific recommendations to strengthen institutional responses to climate migration by the Mexican government and civil society actors to climate migration. 114 articles in 55 journals by 1150 contributing authors

Articles/Reports from Agencies and Non-Governmental Organizations Addressing Aspects of Climate Change

Managing Natural Hazards and Climate Risks in Elections, Asplund et al., International IDEA

Elections are the cornerstone of democracy, but like all public functions they are vulnerable to disruption by events in the natural world, including earthquakes, floods, wildfires and heatwaves. As the climate changes, many natural hazards are increasing in frequency and severity, prompting electoral practitioners to seek ways to protect the vote from such phenomena. The authors survey the risk that meteorological and geological events pose to elections and offers an analysis of the strategies that electoral management bodies (EMBs) around the world have put in place to safeguard electoral processes. The authors draw on a rich database of more than 100 cases of disaster-disrupted elections between 2006 and 2025 to document the various effects that events in the natural world can have on all aspects of the electoral cycle and to delineate the range of strategies that are available to electoral administrators to minimize their adverse consequences.

Solar Permitting Scorecard. Grading all 50 states on removing obstacles to rooftop solar and home batteries, Elizabeth Ridlington and Johanna Neumann, Frontier Group and Environment America Research & Policy Center

The authors reviewed policies relating to the permitting and inspection of residential solar energy systems and battery storage in all 50 states. They found that a majority of states have done little to adopt common-sense practices that reduce the costs and delays that permitting and inspection requirements impose on families wishing to install solar panels and batteries. Only two states – California and Texas – received a “B” in the scorecard, two received a “C,” 24 received a “D” and the remaining 22 received an “F.”

People and Climate Change, Ipsos

As temperatures rise, the individual responsibility to act has fallen. The past 11 years have been the warmest in the modern era, but people increasingly place less responsibility in needing to act. In the last five years, all countries surveyed in the report in both 2021 and 2026 have seen falls in the proportion who agree that individuals would be failing future generations by not acting against climate change. Short-term fear is countering long-term preparation. While climate concern remains present – 59% on average across 31 countries say they country should be doing more in the fight against climate change - more immediate risks are seen as greater priorities. Our What Worries the World survey finds concern about climate change in 11th place, behind more tangible, immediate worries issues like crime, unemployment, and inflation. The energy transition is at a crossroads. Public support for transitioning to clean energy is increasingly conditional, contingent on affordability, reliability, and security trade-offs. The Ipsos Energy Transition Barometer finds one in two (50% across 31 countries) support governments prioritizing low energy prices even if emissions increase.

Extreme Heat and Agriculture, Simpson et al., Food and Agriculture Organization of the United Nations and the World Meteorological Organization

Extreme heat refers to situations where daytime and nighttime temperatures rise above their usual ranges for a protracted period, leading to physiological stress and direct physical damages to food crops, livestock, fish, trees and human beings. The authors examine how extreme heat ripples through agricultural systems and how heatwaves can interact with other climatological variables, including rain, solar radiation, humidity, wind and drought – to trigger compound effects that wreak havoc on individuals and entire ecosystems.

The 2026 Europe report of the Lancet Countdown on health and climate change: narrowing window for decisive health action, Kriit et al., The Lancet Public Health

This third iteration of the Lancet Countdown on health and climate change in Europe report systematically tracks the health effects of climate change adaptation and mitigation action, economics and finance, and the engagement of various societal actors with the climate change and health nexus, drawing on data up to 2025. The report features seven new indicators, methodological updates, extended time series for existing indicators, and highlights inequalities in health risks and impacts where possible.

Climate Change and Migration from Central America: Insights from Migrants in Mexico, Kerwin et al., UC Berkeley School of Law

The authors examine how climate-related harms intersect with and exacerbate violence, exclusion, discrimination, and weak state protection to drive migration from El Salvador, Guatemala, Honduras, and Nicaragua. Drawing on interviews, desk research, and surveys with people on the move in Mexico, the authors show that climate change rarely operates as a single cause of displacement. Instead, migrants consistently describe how environmental shocks—such as droughts that destroy crops, storms that damage homes and livelihoods, and deforestation and extreme heat that undermine health and economic stability—exacerbate existing insecurity and hardship. The authors focus on Mexico as both a transit and destination country for Central American migrants impacted by these dynamics. The findings demonstrate that better understanding how climate change intensifies vulnerabilities to violence, insecurity, and loss of livelihood—and integrating that analysis into refugee and immigration representation and adjudication— can improve access to protection and to regular migration status under Mexico’s existing legal framework. The authors also offer specific recommendations to strengthen institutional responses to climate migration by the Mexican government and civil society actors to climate migration.

High Voltage. The global potential for industrial electrification, Cassandra Etter-Wenzel and Jan Rosenow, Environmental Change Institute, University of Oxford

Industrial electrification is becoming a matter of economic security as well as decarbonization. The authors argue that continued reliance on fossil fuels leaves 75% of global industry exposed to recurring price shocks, while electrification offers a pathway to stable and resilient energy costs.

Trust, Media Habits, and Misperceptions Shape Public Understanding of Climate Change, Marryam Ishaq and M. Speiser, ecoAmerica

A hidden climate majority exists. Most Americans are concerned about climate change, but they do not realize how widely that concern is shared. This perception gap (pluralistic ignorance) masks a strong hidden consensus on climate concern. Trust in information and personal concern about climate change reinforce each other. Americans who trust the information they see or hear are far more likely to be concerned about climate change (79%) — and those who are climate-concerned report higher trust. This creates a reinforcing loop between trust and concern. Media ecosystems shape climate beliefs. Where Americans get their news influences what they believe about climate and energy. While mainstream national media, local news, and social media remain the most widely used sources overall, partisan and age differences shape which sources are most relied on, which in turn shapes climate beliefs. Americans trust the information they encounter but doubt others’ ability to recognize climate misinformation. While many Americans trust the information they personally consume, they are far less confident in others’ ability to distinguish climate fact from fiction — especially when they perceive others as less concerned about climate change. Mistrust of others and misperceptions are core barriers to climate action. Rather than a lack of concern, some of the biggest barriers include eroded trust and misperceptions. Misperceptions about energy sources and others’ climate beliefs, combined with low confidence in the public’s ability to navigate climate misinformation, suppress visible engagement and slow individual and collective action.

Greenhouse Gas Inventory and Analysis for the United States 1990-2024, Desai et al., Center for Global Sustainability, University of Maryland

The authors present a comprehensive picture of greenhouse gas (GHG) sources and sinks covering the geographical region of the United States. The data are presented for each year from 1990 through 2024, the latter being the most recent year when comprehensive data are available for the entire economy. Along with detailed results for single years and analyses of trends over time, the authors present methodological descriptions, data inputs, a characterization of uncertainties, recalculations, and improvements. The report was developed to supports comparability and continuity with past official U.S. inventories prepared by the U.S. Environmental Protection Agency.

From energy crisis to energy security: Actions for policy makers, Walker et al., The International Renewable Energy Agency

The current energy crisis stemming from the conflict in the Middle East re-iterates the inherent structural weakness and vulnerability of national energy systems that remain reliant upon fossil fuels, and markets where the costs of oil and gas are highly influential on electricity prices. There is an immediate opportunity, however, to urgently reassess these fundamentals and prioritize reactions that enhance long-term energy stability. The authors provide key short- medium- and long-term actions for policy makers responding to the present crisis. Policy makers must urgently consider intervening to direct investment and emergency responses to accelerate the deployment of renewable power generation capacity, and the electrification of energy-consuming processes and sectors.

State of Energy Policy 2026, Cozzi et al., International Energy Agency

The authors provide a unique review of policy progress made in 2025 across all energy sectors and instruments, with a special focus on government spending, energy efficiency regulations, and the contribution of the energy sector to nationally determined contributions and long-term net zero pledges. This year’s report brings an extensive examination of energy security policies to the period 1973-2025, from oil and natural gas to clean energy technology supply chains and critical minerals. It also spotlights the policy momentum around energy access, most particularly in sub-Saharan Africa, taking stock of the policy progress since the IEA Summit on Clean Cooking in Africa in 2024.

2025 State of the Heat Pump Water Heater Market Report, New Buildings Institute and the Advanced Water Heating Initiative

The authors discuss how residential and commercial manufacturers released more new and updated products in 2025 than any other year in the heat pump water heater's (HPWH) history. Five new residential manufacturers brought HPWHs to market, and many other established manufacturers brought updated and increasingly innovative products to market. New configurations and form factors also emerged, from flexible voltage (120-volt and 240-volt in the same unit) products, to split systems (where the compressor and tank are separated), to high temperature commercial and industrial HPWHs, to HPWHs with thermal storage.

Climate Change & Adaptation. Rethinking climate risk integration across business, finance and policy, Holloway et al., FTI Consulting

Financial institutions, corporate executives and investors are operating with climate risk models that systematically underestimate exposure by a factor of two to four times. This is not a compliance issue, instead it represents one of the most significant mispricing phenomena in modern capital markets, materializing today across credit spreads, equity valuations and capital allocation decisions. The authors analyzed 148 global companies representing $31.4 trillion in market capitalization to test whether current climate risk models provide decision-useful intelligence. The findings are stark: conventional platforms project approximately 2.0% portfolio losses, while the author's integrated analysis reveals 7.7% average exposure – a four-fold gap that stems from systematically underweighting transition risks relative to physical climate impacts.

WASHINGTON (AP) — Burning time for North American wildfires is going into overtime. Flames are lasting later into the night and starting earlier in the morning because human-caused climate change is extending the hotter and drier conditions that feed fires, a new study found.

Fires used to die down or even die out at night as temperatures dropped and humidity increased, but that’s happening less often. The number of hours in North America when the weather is favorable for wildfires is 36% higher than 50 years ago, according to a study published earlier this month in Science Advances.

Places such as California have 550 more potential burning hours than in the mid-1970s. Parts of southwestern New Mexico and central Arizona are seeing as many as 2,000 more hours a year when the weather is prone to burning fires, the highest increase seen in the study, which looked at Canada and the United States. The research looked at times when conditions were ripe for fire, but that didn’t mean fires occurred during all that time.

Recent big fires in LA and Hawaii burned at night

Fires that surge at night are tougher to fight and included the Lahaina, Hawaii fire in 2023, the Jasper fire in Alberta in 2024, and the Los Angeles fires in 2025, the study said. Maui’s fire ignited at 12:22 a.m.

It’s not just the clock that is getting extended. The calendar is too. The number of days with fire-prone weather increased by 44%, which effectively added 26 days over the past half-century.

It’s mostly from warmer, drier nighttime weather, with a bit of extra wind, the study authors said.

“Fires normally slow down during the night, or they just stop,” said study co-author Xianli Wang, a fire scientist with the Canadian Forest Service. “But under extreme fire hazard conditions, fire actually burns through the night or later into the night.”

And Wang said Earth’s warming atmosphere means it’s like to get worse.

Tougher to fight fires at night

Fires that don’t “go to sleep” get a running start the next day, making it harder to knock them down, University of California, Merced fire scientist John Abatzoglou, who wasn’t part of the study, said in an email.

“Nights aren’t what they used to be — that is, more reliable breaks for wildfire,” he added. “Widespread warming and lack of humidity is keeping fires up at night.”

Wildland firefighter Nicholai Allen, who also founded a firm that makes home fire prevention tools, said it’s very difficult to fight fires at night.

“You have to understand that you have snakes and bears and mountain lions and all the stuff you have in daytime,” Allen said, noting a colleague was bitten by a bear. “But at night, they’re really scared, and they’re running away from the fire.”

The Canadian researchers analyzed nearly 9,000 larger fires from 2017 to 2023 using a weather satellite and other tools to get hour-by-hour data on atmospheric conditions during the fires, such as humidity, temperature, wind, rain, and fuel moisture levels. They created a computer model that correlated weather conditions and fire status and applied to historical data in Canada and the United States from 1975 to 2106.

Nights are warming faster than days

Scientists have long said heat-trapping gases from the burning of coal, oil, and natural gas make nights warm faster than days because of increased cloud cover that absorbs and re-emits heat down to Earth at night like a blanket. Since 1975, summers in the contiguous U.S. have seen nighttime lowest temperatures warm by 2.6 degrees Fahrenheit (1.4 degrees Celsius), while daytime highest temperatures have gone up 2.2 degrees Fahrenheit (1.2 degrees Celsius), according to the National Oceanic and Atmospheric Administration.

Humidity at night “doesn’t rebound” from its daytime dryness like it used to, said study lead author Kaiwei Luo, a fire science researcher at the University of Alberta.

Wildfires often coincide with drought, especially extreme drought, which means not only drier air, but hotter, drier air that sucks up more moisture from the ground and plants, making fuels for fire more flammable, Wang said. In a drought, there’s often a vicious circle of drying and when it is quite dry, a warmer atmosphere has more power to suck moisture out of fuels.

Just as warmer nights, especially in heat waves, don’t let the body recover, the warmer nights are not allowing forests to recover, Wang said. It can take weeks for dead fuel to recover its lost moisture and be less fire-prone, he said.

“It’s just a stress to the plants,” Wang said. “That also increases fuel load.”

From 2016 to 2025, wildfires in the United States on average burned an area the size of Massachusetts each year, slightly more than 11,000 square miles (28,500 square kilometers). That’s 2.6 times the average burn area of the 1980s, according to the National Interagency Fire Center. Canada’s land burned on average for the last 10 years is 2.8 times more than during the 1980s, according to the Canadian Interagency Forest Fire Centre.

Syracuse University fire scientist Jacob Bendix, who wasn’t part of the research, called the study a sobering reminder of climate change’s role in driving “increased fire potential across almost all of the fire-prone environments of North America.”

This is a re-post from The Climate Brink by Andrew Dessler

I am finalizing a textbook on climate risk and am posting chapters as I finish them. I’d previously posted chapters about embedded energy and physical climate risk; this post is a chapter on transition risk, the economic and social risks of the transition to a clean-energy economy.

Introduction

In the context of climate risk, transition risk encompasses the economic and social risks associated with a shift towards a low-carbon economy. Such an effort would fundamentally reshape our world and create critical financial uncertainty for assets and industries tied to the old, carbon-intensive system.

Net zero

Reaching “net zero” is the ultimate goal of most climate policy. This means reducing greenhouse gas emissions as much as possible, with any remaining emissions that are too difficult or costly to eliminate are canceled out by an equivalent amount of “negative emissions” — processes that actively pull carbon dioxide out of the atmosphere. These negative emissions are the “net” part of net zero and it acknowledges the practical reality that some sectors, like long-distance air travel or ocean shipping, may be incredibly difficult to decarbonize in the near future.

What are these negative emissions technologies? The two primary methods discussed are Direct Air Capture (DAC), which uses machines to filter carbon dioxide directly from the air, and Bioenergy with Carbon Capture and Sequestration (BECCS), which involves growing crops, burning them for energy, and capturing and burying the resulting carbon dioxide. However, both technologies face significant hurdles, including high costs, large energy requirements, and, in the case of BECCS, immense land use needs that could compete with food production and biodiversity.

Once we reach net zero, global temperatures will stabilize — although they won’t recover to pre-industrial levels for tens of thousands of years. Getting the climate to actually cool on time scales we care about (decades to centuries) would would require pulling even more carbon dioxide out of the atmosphere, or deploying some type of climate engineering approach like injecting aerosols into the stratosphere.

The scale of the net zero transformation means that reaching net zero will fundamentally overhaul vast parts of the global economy. Many big sectors of our economy — energy, transportation, industry, agriculture — must be reshaped, and that reshaping will create enormous opportunities as well as painful dislocations. The transition to a low-carbon economy is not simply a matter of swapping one energy source for another; it requires rebuilding infrastructure, retraining workers, and redirecting trillions of dollars in investment.

Some industries are poised to prosper. Renewable energy is the most obvious example: in 2025, the world added over 700 GW of new capacity, and sustaining that pace for decades will require ongoing investment in manufacturing, installation, and maintenance of wind turbines and solar panels. The profits for those well positioned will be enormous.

The electric vehicle industry and its supply chains — from battery manufacturers to mining operations for lithium and cobalt — also stand to grow dramatically. Companies that build and manage electrical grid infrastructure, including new transmission lines and energy storage systems, will see surging demand. So too will firms specializing in energy efficiency, building retrofits, and emerging technologies like green hydrogen and sustainable aviation fuels. Even agriculture could see new revenue streams as farmers are paid to adopt practices that sequester carbon in soil.

Other industries, however, face serious decline. Fossil fuel producers (coal, oil, and natural gas) confront the prospect of their core product becoming obsolete, stranding assets worth trillions of dollars. Workers in these industries, from coal miners to oil rig operators, risk losing their livelihoods.

The effects extend well beyond extraction: refineries, pipelines, and petrochemical plants all face an uncertain future. The automotive sector will also see significant disruption, as the shift to electric vehicles renders the internal combustion engine and its complex supply chain of transmissions, exhaust systems, and fuel injection components irrelevant. Communities built around these industries may face economic devastation if the transition is not carefully managed.

This uneven distribution of winners and losers will create difficult economic and political challenges, particularly during the transition period. The enormous capital investment required — in renewable generation, grid modernization, EV charging infrastructure, industrial retooling, and carbon removal — must be mobilized quickly, creating the risk of supply chain bottlenecks, inflation in key materials, and financial instability. Managing this transition in a way that is both fast enough to meet climate targets and equitable enough to maintain broad public support is one of the defining policy challenges of our time.

Stranded assets

A core concept in transition risk is the “stranded asset”. A stranded asset is defined as an asset that loses significant value well before the end of its expected economic life. This loss is often sudden and unexpected, driven by changes in market conditions, technology, or policy. While this can happen for many reasons, it is a particularly potent risk in the context of climate change, arising from both direct physical impacts and the economic shifts of the energy transition.

For example, here is a house that literally fell into the ocean in North Carolina in Sept. 2025:

From Zillow.com, this was a pricey house:

link

 

This house could have stood for another few decades, but it collapsed into the ocean due to coastal erosion that was certainly made worse by sea level rise. When that happened, its value instantly dropped to zero, a stark, nonlinear impact that produced a stranded asset.

While physical risks can strand assets, the concept first gained prominence in discussions about transition risk and the fossil fuel industry. Oil and gas companies are valued in the trillions of dollars, with much of that valuation based on their proven reserves—oil and gas that is in the ground and ready to be produced. The transition to a net-zero economy, however, requires that a significant portion of these reserves be “left in the ground” and never burned. Once the market fully accepts that these assets cannot be produced due to climate policies, their value could drop to zero rapidly.

The danger of these fossil fuel assets becoming stranded extends far beyond the energy companies themselves. It poses a systemic risk to the broader economy because large swaths of the general public have financial exposure to these companies through their investments, including 401k programs, pensions, and mutual funds. The sudden devaluation of these energy assets could negatively affect many people’s investment and retirement funds, which in turn could have a widespread and devastating impact on the financial security of the general public.

This same principle applies to the real estate sector. Consider a commercial office building with a low energy efficiency rating located in a city that passes a new ordinance mandating high-performance standards for all buildings. The owner is suddenly faced with a difficult choice: either undertake a costly, large-scale retrofit to meet the new legal requirements or risk being unable to legally rent the space. If the retrofit is too expensive, the building’s value is stranded, as its primary function — generating rental income — has been eliminated by a policy change aimed at reducing emissions.

Another often-overlooked category of risk lies in intangible assets. For companies in the S&P 500, these assets — such as brand value, reputation, and intellectual property (IP) — can represent up to 90% of their total market value. Their non-physical nature makes them vulnerable to rapid devaluation. For example, imagine a company that holds a highly valuable portfolio of patents for a new, efficient diesel engine technology. If a major country or region, aiming to meet climate targets, decides to ban the sale of all new diesel cars, the market for that technology disappears. The intellectual property, once a significant asset, has its value evaporate almost overnight. This is a direct parallel to the risk facing fossil fuel companies, whose reserves — a tangible asset on paper — could become worthless if they cannot be produced.

A final critical category that is often overlooked is human capital. Human capital represents the skills, knowledge, and expertise that workers have developed over their careers — assets that can suddenly lose their value in the transition to a low-carbon economy.

Consider a mechanic who has spent 30 years perfecting the art of repairing internal combustion engines. This individual has accumulated expertise in diagnosing problems, understanding the mechanical systems, and maintaining gasoline-powered vehicles. As the world shifts to electric vehicles — which require fundamentally different maintenance skills — this expertise becomes obsolete. The mechanic’s human capital, built over decades, is stranded.

The scale of this challenge is enormous. Huge numbers of workers have built their careers in fossil fuel industries. Coal miners possess specialized knowledge about underground operations, safety protocols, and extraction techniques. Oil field workers understand drilling technologies, reservoir management, and petroleum systems. Pipeline operators and refinery technicians have invested years developing skills specific to a carbon-intensive economy. As these industries contract or disappear entirely, these workers face the prospect of their expertise becoming rapidly becoming worthless.

This creates both an economic and social crisis. Unlike a stranded power plant that can be written off a company’s books, stranded human capital represents real people with families, mortgages, and communities that depend on their income. A 50-year-old coal miner cannot simply retrain as a software developer overnight. The geographical concentration of these industries compounds the problem — entire regions have been built around fossil fuel extraction, creating communities where the primary source of skilled employment may disappear.

The human dimension of stranded assets also creates political risk for the climate transition itself. Workers facing the loss of their livelihoods can become powerful opponents of climate action, slowing the transition for everyone. The fear and anger generated by the transition can translate into political movements that resist or reverse climate policies, as workers vote to protect their immediate economic interests over longer-term economic reality.

The TCFD Framework: Four Key Drivers of Transition Risk

To better understand and manage transition risks, the Task Force on Climate-related Financial Disclosures (TCFD) developed a framework that organizes these risks into four distinct categories. This framework has become the global standard for how companies and investors think about and report climate-related financial risks.

1. Policy and Legal Risks

Policy and legal risks emerge when governments and courts take action to address climate change. These interventions can fundamentally alter the economic landscape, often with little warning.

Carbon pricing represents one of the most direct policy tools. When governments implement a carbon tax or cap-and-trade system, they make it more expensive to emit CO2. For instance, a carbon price of $50 per ton of carbon dioxide would add around $20 to the cost of a barrel of oil, fundamentally changing the economics of oil production and consumption. Companies that built their business models around cheap fossil fuels suddenly face dramatically higher operating costs.

Efficiency standards create another layer of policy risk. The UK’s Minimum Energy Efficiency Standard (MEES) provides a clear example: it prohibits landlords from renting properties with poor energy efficiency ratings. A landlord who owns an older, inefficient building faces a stark choice — invest heavily in retrofits or watch the property become unrentable, thereby creating a stranded asset.

The legal dimension adds another layer of risk through climate litigation. There are many lawsuits winding through the courts where people are taking fossil fuel companies to court because they have been or expect to be harmed by climate-change-driven extreme weather. This potential climate liability could expose fossil fuel companies to enormous financial risk, much like tobacco companies faced when the health impacts of their products became legally actionable.

2. Technology Risks

Technology risk represents the classic story of disruption — when a new, cheaper, or better technology makes existing technologies obsolete. In the climate context, this risk is accelerating as clean technologies have reached critical tipping points.

The most dramatic example is the drop in renewable energy costs. Solar power costs have fallen nearly 90% over the past 15 years. In most parts of the world, building a new solar or wind farm is now cheaper and faster than building a new coal or gas plant — even without subsidies. This is rapidly reordering energy economics and energy markets. Coal plants that were expected to operate profitably for 40 years are being shut down early not because of regulation, but because they simply can’t compete economically with cheaper energy sources. Natural gas plants will be next.

Electric vehicles present another technological disruption. As battery costs decline and performance improves, EVs are becoming not just environmentally preferable but superior products — they accelerate faster, require less maintenance, and increasingly cost less to own and operate than internal combustion engines. This technological shift threatens not just automakers who are slow to adapt, but entire ecosystems built around gasoline vehicles: gas stations, oil change shops, parts suppliers, and even dealerships whose business models depend heavily on service revenue from complex internal combustion engines.

3. Market Risks

Market risks encompass the shifts in supply, demand, and investor sentiment that can rapidly revalue assets and companies.

As an example, demand for transition minerals like lithium, cobalt, and copper is soaring as the world builds batteries and renewable energy infrastructure. Companies that secured supply chains for these materials early have gained significant competitive advantages, while those arriving late face production bottlenecks and inflated costs. Conversely, demand for thermal coal is collapsing in many regions, leaving coal mining companies with reserves that may never be extracted.

Perhaps more significant is the shift in investor perceptions. For decades, oil companies were valued based on their proven reserves — the oil and gas they had rights to extract. Now, many investors view these same reserves as worthless, unburnable carbon that will never generate revenue. This shift in perception led BP to write down its assets by $17.5 billion in 2020, with Shell following with a $22 billion write down. These companies acknowledged that much of their oil would likely remain in the ground forever.

The power of changing investor sentiment was dramatically demonstrated in 2021 when Engine No. 1, a tiny activist hedge fund, successfully won three board seats at ExxonMobil. Their argument wasn’t environmental but purely financial: Exxon’s failure to plan for the energy transition was destroying long-term shareholder value. This showed that transition risk has moved from the margins to the center of corporate governance.

4. Reputational Risks

Reputational risk reflects the changing expectations of consumers, employees, and society at large. As public concern about climate change grows, companies associated with high emissions face damage to their brands and their social license to operate.

The financial sector illustrates how reputational concerns translate into business decisions. In 2019, Goldman Sachs announced it would no longer finance new thermal coal mines or Arctic oil exploration. While framed partly in risk management terms, the bank explicitly cited reputational considerations and changing client expectations as key drivers. They recognized that being associated with these projects was becoming bad for business, potentially costing them clients and talented employees who increasingly consider environmental factors in their career choices.

Consumer pressure is also reshaping entire industries. The rapid growth of plant-based milk alternatives like Oatly directly responds to, among other things, consumer concerns about dairy’s environmental impact. Traditional dairy companies, seeing their market share erode, are scrambling to launch their own non-dairy alternatives. This shift isn’t driven by regulation or technology costs but by changing consumer preferences that make high-emission products less desirable, regardless of price or quality.

5. Putting it together

These four categories of risk — policy and legal, technology, market, and reputation — don’t operate in isolation. They interact and amplify each other, creating feedback loops that can accelerate the transition and magnify risks for unprepared economies.

Consider how technological advances in renewable energy trigger cascading effects across all risk categories. As solar and wind become cheaper than fossil fuels (technology risk), governments gain political cover to implement stricter emissions standards and carbon pricing (policy risk), knowing these policies won’t dramatically increase energy costs for voters. These policies, in turn, shift investor capital away from fossil fuels and toward renewables (market risk), further driving down clean energy costs through economies of scale. Companies slow to adapt find themselves not just technologically obsolete but facing reputational damage for clinging to outdated, polluting technologies (reputational risk), which makes it even harder to attract capital, customers, and talent.

The automotive industry provides another vivid example of these interconnected risks. As electric vehicles improve and battery costs fall (technology risk), governments implement EV mandates and phase out internal combustion engines — Norway by 2025, the UK by 2030 (policy risk). These policies signal to investors that traditional automakers without credible EV strategies are poor long-term investments, triggering capital flight (market risk). Meanwhile, young consumers increasingly view gas-powered vehicles as environmentally irresponsible, especially luxury gas vehicles (reputational risk). Each risk reinforces the others: technological improvements justify stricter policies, which shift market dynamics, which shape public perception, which in turn creates pressure for even more aggressive policies and faster technological development.

Understanding these interconnections is essential for understanding transition risk. A company cannot address one type of transition risk while ignoring the others — they must recognize that these risks compound and prepare for the systemic changes that result from their interaction.

The “Just Transition”

The recognition that the shift to a low-carbon economy will create winners and losers, particularly among workers and communities reliant on fossil fuel industries, has given rise to the concept of a just transition. A just transition is an effort to ensure that the benefits of a green economy are shared broadly and that the costs do not fall unfairly on those who can least afford them.

The core idea is to provide support, retraining, and new economic opportunities for workers and communities whose livelihoods are threatened by the phase-out of carbon-intensive industries. This is not merely an ethical consideration; it is a pragmatic one. The threat of widespread job losses can create powerful political opposition to climate action, potentially slowing down or even derailing the transition for everyone. Therefore, managing the human side of the transition is critical to its success.

In a just transition, we would repurpose skills: For example, the skills required to build an offshore oil rig are similar to those needed for constructing an offshore wind platform. A just transition would facilitate this shift through targeted programs.

The private market is unlikely to manage this process efficiently or equitably. Government action is therefore needed to fund retraining programs and help workers seamlessly switch to new jobs in the growing green economy.

Germany’s approach to phasing out coal mining in its Lausitz region serves as a prominent example. The German government is investing €40 billion to manage the process by funding new infrastructure, research institutes, and extensive retraining programs. The goal is not just to compensate for lost jobs but to actively build a new, sustainable economic future for the region.

Conclusion

Transition risk represents a fundamental restructuring of the global financial and social order. As this chapter has detailed, the journey toward a net-zero economy is far more than a simple technological swap. It is a complex, multi-dimensional shift driven by the interplay of policy, technology, and market and social dynamics. While this transition offers immense opportunities for innovation and growth in green sectors, it simultaneously creates the systemic threat of stranded assets — devaluing not just physical infrastructure and fossil fuel reserves, but also intangible intellectual property and the human capital of millions of workers.

Ultimately, the success of this overhaul hinges on the ability to manage these risks. Because the private market is not naturally equipped to solve the social dislocations caused by such rapid change, proactive governance and strategic investment are essential to ensure a just transition, so that the shift to sustainability does not leave vulnerable communities behind. Balancing the urgent need for decarbonization with the economic security of the workforce is not just a moral imperative, but a practical necessity to maintain the political and social stability required to reach our climate goals.

This is a draft of a section of my climate risk textbook (slightly edited & reformatted to make it appropriate for Substack). I’d very much like to identify errors now, so if you see any, please let me know in the comments.

This is a re-post from Yale Climate Connections by Jeff Masters

October 28, 2025, was a very bad day to be in Jamaica. That morning, Category 5 Hurricane Melissa intensified into the strongest hurricane ever observed in the Atlantic: 190 mph (305 km/h) winds, a tie with Hurricane Allen of 1980. That afternoon Melissa powered ashore in Jamaica, causing a catastrophic $8.8 billion in damage, equivalent to 41% of Jamaica’s GDP.

Melissa came close to its maximum potential intensity

The maximum potential intensity of a tropical cyclone is the maximum strength a storm can achieve based on the existing atmospheric and oceanic conditions. Potential intensity theory was pioneered in 1987 by MIT hurricane scientist Kerry Emanuel, who showed that human-caused global warming will increase the maximum strength that a hurricane can achieve. Hurricanes are heat engines that take heat energy out of the ocean and convert it to the kinetic energy of wind, so it makes sense that the winds of the strongest hurricanes will get stronger as the oceans heat up.

Melissa’s 190-mph winds were very close to its maximum potential intensity: The hurricane’s maximum potential intensity was about 197 mph (317 km/h), according to the SHIPS model, and about 200 mph (320 km/h), according to a graphic available at the University of Wisconsin’s CIMSS (Fig. 1). It is quite rare for a hurricane to come this close to its maximum potential intensity — all conditions have to be perfect, and the atmosphere and ocean make up a complex system where perfection is rarely achieved.

Figure 1. The maximum potential intensity (MPI) of Hurricane Melissa on Oct. 28, 2025, was about 175 knots (200 mph). (Image credit: University of Wisconsin’s CIMSS)

Given the less-than-ideal conditions for intensification – light to moderate wind shear of 5-15 knots, a very slow forward speed of less than 5 mph that allowed upwelling of cooler water from the depths to affect it, and interaction with the rugged terrain of Jamaica – Melissa came remarkably close to its maximum potential intensity. (The formula for maximum potential intensity does not include wind shear and slow hurricane motion.)

So how strong could Melissa have gotten if everything were going its way? Melissa formed in late October, when ocean temperatures were about 30 degrees Celsius (86°F). Six weeks earlier, during the early- to mid- September peak of sea surface temperatures, ocean temperatures in the central Caribbean were near 31 degrees Celsius (88°F). According to a 2023 paper, the maximum potential intensity increases 5-7% per degree Celsius of sea surface temperature increase. Thus, Melissa’s maximum potential intensity would have increased by about 11-15 mph (18-25 km/h) had it formed during the September peak in sea surface temperatures. If we assume the other factors limiting its intensification were not present, Melissa could have peaked with 215 mph (345 km/h) winds.

This is the same intensity achieved by the strongest known hurricane in world history, 2015’s Hurricane Patricia. Patricia formed off the Pacific coast of Mexico over record-warm waters of 30.5-31 degrees Celsius (87-88°F). And though the difference between 180 mph and 215 mph may not seem like much, it would actually represent about a fourfold increase in damage potential, according to NOAA.

Figure 2. The strongest tropical cyclones observed globally, 1972-2025, using windspeed ratings from the National Hurricane Center for the Atlantic and Eastern Pacific and from the Joint Typhoon Warning Center elsewhere.

How strong can a hurricane get?

The global list of tropical cyclones during the satellite era (1972-present) with winds as strong or stronger than Melissa is a short one: just 11 storms (Fig. 2). (There were 19 Western Pacific typhoons from 1955-1966 that “officially” have winds of 195 mph or higher, but hurricane experts agree that the intensities assigned to typhoons during that pre-satellite period suffered from a high bias and are not reliable.)

For most of the Northern Hemisphere’s tropical cyclone-prone areas, September will be the month with the highest possible maximum potential intensity, since that is when sea surface temperatures peak. Emanuel, the MIT hurricane scientist, created maps of the top 10% maximum potential intensity expected within 1,000 km of a given point during September, using climate data from the period 1982-1995 (Fig. 3). In the Atlantic, the Gulf of Mexico and western Caribbean have the highest values: 224 mph (100 m/s) or higher. In the Pacific, the southern Philippines, Mexico, and most of Central America also have a top 10% maximum potential intensity of 224 mph (100 m/s) or higher.

Figure 3. Top 10% maximum potential intensity winds within 1,000 km of a given point for tropical cyclones expected during September, using climate data from the period 1982-1995. The only places with an MPI in excess of 110 m/s (246 mph) are the ocean areas of the Middle East. (Image credit: Kerry Emanuel)

Emanuel also created a table showing the top-10% maximum potential intensities for individual cities across the globe. All of these numbers (and the ones in Fig. 3) need to be adjusted upward because the climate has warmed significantly since the 1995 cutoff of the historical data used. A 2022 paper, A potential explanation for the global increase in tropical cyclone rapid intensification, reported that between 1982 and 2017, potential intensity during August-September-October in the Northern Hemisphere tropics increased by 2.3-2.4 mph per decade, or 8.6 mph over the 36-year period (1.02-1.06 m/s per decade). During that same period, Northern Hemisphere tropical sea surface temperatures increased by 0.17-0.23 degree Celsius per decade, or 0.6-0.8 degree Celsius over the 36-year period. A 2021 paper, Poleward expansion of tropical cyclone latitudes, reported similar numbers, with larger increases in potential intensity observed in the eastern Caribbean and western Gulf of Mexico.

These results suggest that the maximum potential intensity numbers in Fig. 3 and in Emanuel’s table should be adjusted upward by about 9 mph (4 m/s). Here are the adjusted numbers for the U.S. from Emanuel’s table showing the top-10% maximum potential intensities for individual cities:

Boston: 78 mph (35 m/s), Cat 1
Honolulu: 186 mph (84 m/s), Cat 5
Miami: 226 mph (101 m/s), Cat 5
Galveston: 220 mph (98 m/s), Cat 5
New Orleans: 231 mph (103 m/s), Cat 5
New York City: 112 mph (50 m/s), Cat 2
San Diego: 72 mph (32 m/s), Tropical Storm
Washington D.C.: 105 mph (47 m/s), Cat 2

Note that for cities like Boston and Washington, D.C., fast-moving storms coming from the south – where they typically move over warmer waters – can arrive at these cities at a strength higher than the local maximum potential intensity. This is why there is a separate entry in Emanuel’s table for the highest maximum potential intensity within 1,000 km of each city. I didn’t show this quantity in the list above, though it is plotted in Fig. 3.

A 300-mph (134 m/s) tropical cyclone is possible in the Persian Gulf

Globally, the highest maximum potential intensities are found in the ultrahot waters of the Middle East. There has never been a tropical cyclone observed in the Persian Gulf because it is narrow and prone to high wind shear and dry air. 

Figure 4. Category 1 Tropical Cyclone Gulab makes a bid at entering the Persian Gulf on Oct. 3, 2021. (Image credit: NASA World View)

However, for their eye-popping 2015 paper, Grey swan tropical cyclones, Ning Lin and Kerry Emanuel performed modeling showing that strong tropical cyclones can move through the Persian Gulf, representing an underappreciated threat to major cities like Dubai. The modeling showed that a sea surface temperature of 35 degrees Celsius (95°F) can create a maximum potential intensity of 296 mph (132 m/s) in the Persian Gulf. Their worst-case 1-in-30,000-year storm was a 257 mph (115 m/s) Category 5 beast with a central pressure of 784 mb that brought a colossal storm surge of 24 feet (7.5 meters) to Dubai.

The study used the climate of 1980-2010, and sea surface temperatures in the Persian Gulf have warmed significantly since then. Over the period 1981-2012, the Persian Gulf had peak summer sea surface temperatures of 32-35 degrees Celsius (90-95°F). But in July 2020, those temperatures hit 37.6 degrees Celsius (99.7°F). More recently, in August 2023, sea surface temperatures above 36 degrees Celsius (97°F) were measured over portions of the Persian Gulf. Thus, an even stronger storm – with winds over 300 mph (134 m/s) – would be possible in today’s climate.

There has been a recent close call for a strong tropical cyclone entering the Persian Gulf: In 2021, Category 1 Tropical Cyclone Gulab (Fig. 4) entered the Gulf of Oman, which connects to the Persian Gulf. A four-day forecast from the HWRF model (Fig. 5) predicted Gulab would pass over Dubai in the United Arab Emirates, enter the Persian Gulf, and then intensify into a Category 2 storm with a central pressure of 958 mb. Fortunately, Gulab ended up weakening into a tropical storm and making landfall in Oman, near the entrance to the Persian Gulf.

Public Misunderstandings about Climate Solutions (1 article)

• Trust, Media Habits, and Misperceptions Shape Public Understanding of Climate Change Most Americans are concerned about climate change, but they don’t think most others share that concern. That quiet misunderstanding is one of the biggest barriers to climate action in the United States. This report explores how trust in information, media consumption patterns, and perceptions of others shape how people think about climate change. The findings point to a striking paradox: while many Americans trust the information they encounter and are concerned about climate change, they believe others are far less concerned and less able to recognize accurate information. ecoAmerica, Marryam Ishaq , Apr 09, 2026.

This is a guest blog post by John Lang about his new "Climate Trunk" graphics project and website. He will add one graphic per week for about 2 years rounding out the big picture of human-caused climate change graphic by graphic.

If you had to explain climate change in 10 seconds, what would you say? 

Climate scientists Katharine Hayhoe and Kimberly Nicholas have long boiled it down to five phrases: It’s real. It’s us. It’s bad. We’re sure. And we can fix it.

This framing has helped millions cut through a topic swamped by jargon, acronyms and complexity. The first four Climate Trunk graphics owe a debt to that tradition. 

You’ll notice below I leave one off: we’re sure. Not because scientific certainty doesn’t matter. It does. The evidence is overwhelming. Scientists have passed the gold standard of certainty on human-caused climate change: the five-sigma level. The scientific consensus is as solid as gravity – and like gravity, it doesn’t care what you believe. 

I just don’t want to start on the defensive. I want to start by showing the big picture as simply as possible – ‘we’re sure’ will get its own graphic later. 

With that caveat out of the way, here’s the Trunk version of the really big picture:

1. It’s real.

Earth is heating.

Global temperatures are rising, and faster than most people realise. The planet has heated by around 1.3°C since the late 19th century, with the bulk of that increase concentrated in the last 50 years. Land – where people tend to live – has heated by about 2°C on average already. (Ocean takes longer to heat up than land.)

In 2024, the global average reached 1.53°C above the pre-industrial baseline. That doesn’t mean the 1.5°C temperature goal of the 2015 Paris Agreement has been breached, since that threshold refers to the long-term average, not a single year. But it’s a warning that we’re inching closer.

2. It’s us.

And it's 'unequivocal'.

Modern global heating is overwhelmingly caused by human activity. The best estimate of the human contribution is around 100%, and possibly a little more, because natural factors have likely had a slight cooling influence over the last 50 years or so.

Our greenhouse gas emissions, namely CO2, acts like an extra blanket, trapping more heat. Meanwhile, air pollution has removed a little of that blanket by reflecting some sunlight back to space, but only temporarily. Natural factors like the sun and volcanoes do not explain the long-term heating trend.

As the IPCC puts it: ‘It’s unequivocal that human influence has warmed the atmosphere, ocean and land.’

3. It’s bad.

The future has not been written.

Climate change is not just a gradual rise in temperature. It is a destabilisation of the conditions under which human civilisation developed. Food systems, water supplies, infrastructure, ecosystems and political institutions were built under, and for, a relatively stable climate. That stability is now being disrupted at speed.

The risks rise with every increment of heating: more extreme heat, heavier rainfall, worsening droughts, greater strain on nature and growing odds of ‘double whammy’ shocks across societies. The future is far from pre-written, but it will branch according to the choices made by societies over the next decade or so.

4. We can fix it: net zero

Net zero is the only way to stabilise rising temperatures.

This is the part that sometimes gets lost, between ‘it’s too late’ and ‘everything’s fine’. Or, as the late scientist Stephen Schneider put it: ‘the “end of the world” or “good for you” are the two least likely [climate] outcomes.’

We know that achieving net zero CO2 is the only way to stabilise rising temperatures, and the first step towards net zero greenhouse gases. Net zero means cutting emissions as far and as fast as possible, then using durable removals to counterbalance what’s left – the ‘residual’ emissions we can’t eliminate entirely. Net zero also means protecting the land and ocean sinks that already absorb about half of our CO2 emissions.

Durable removals will help, they have to. But emission cuts will do the heavy lifting. Cutting emissions now is almost always easier and cheaper than trying to remove them from the atmosphere later.

In a nutshell, the practicalities of net zero are almost as simple as Hayhoe and Nicholas’s five climate basics:

• replace fossil fuels with clean energy
• electrify energy systems as fast as possible
• protect, restore and strengthen land and ocean sinks
• scale up durable carbon removal to industrial levels.

The good news is the first two above are underway, and moving faster than many expected.

Clean energy is beginning to grow in line with — and at times faster than — energy demand: the key to squeezing fossil fuels out over time. Slowly at first. Then all of a sudden. 

Solar has gone bananas. Together with wind, it now accounts for more than 90% of new power capacity. Clean electricity has surged past 40% of global generation, helping put a brake on CO2 emissions growth since 2015.

Yes, the norm-wrecking ball in the White House has dented investment confidence. But global spending on clean energy is roughly double that of fossil fuels – and growing. Meanwhile the Iran crisis is rewriting energy policy in real time: away from imports and volatility, and towards energy sovereignty, stability and lower fuel import bills.

As veteran energy analyst Michael Liebreich reminds us, we’re now about one-third through the energy transition in final energy terms. We're also close to a tipping point, where a China-led plateau in emissions should turn into a structural global decline.

Which brings us back to the most important of Hayhoe and Nicholas’s basics: we can fix it. We’re making progress – even if you can’t always see it.

Net zero isn’t a political slogan or culture war football. It’s physics and chemistry. And it’s the only way to stop global heating.
