Climate Change at Work
By NRDC - Grist, July 19, 2022
Last summer, the Pacific Northwest was hit by a once-in-a-millenium heat dome. While temperatures were higher than ever recorded, L.A.* was outside, working Washington’s blueberry harvest. (Fearing potential work repercussions, L.A. did not wish to be identified by her full name.) Soon, she was dehydrated, dizzy, and vomiting. Her minor son, who was also working in the field out in the heat, got a bloody nose and headache. When the harvest was moved to the middle of the night to avoid the most intense heat—”to protect the fruit, not the workers,” L.A. says—her friend cut herself badly laboring in the dark.
Whether it’s heatwaves, wildfire smoke, or attempts to adapt that create new hazards, the climate crisis is exacerbating risks for America’s workers. From home health aides and school teachers to construction and farm workers, people across the country are now facing compounding challenges on the widening frontlines of the climate crisis. Yet federal protections for the workplace have not kept pace.
During California’s recent wildfires, shocking photos emerged of farmworkers harvesting grapes in California vineyards under an orange-tinged sky. That may be one of the most visible examples of people being forced to work in dangerous conditions, but it’s far from the only climate-related health risk employees regularly face. “The reality is that millions of workers—across our society—are being exposed to multiple environmental stressors all at once, including searing heat and toxic air pollution,” says Dr. Vijay Limaye, senior scientist at the Natural Resources Defense Council (NRDC).
For instance, Limaye explains that the formation of ground level ozone—air pollution formed in the atmosphere from building blocks including emissions from burning coal, oil, and gas—is intensified by hotter temperatures. The Environmental Protection Agency (EPA) is responsible for setting exposure limits, but the agency’s models often don’t account for compounding circumstances or cumulative impacts. While the EPA sets some legal limits for ozone, for example, outdoor workers are frequently exposed to smog and extreme temperatures simultaneously. From a health risk perspective, “the sum is often greater than the parts,” Limaye says.
