Drained Under Soviet Rule, Aral Sea Has Become a Huge Source of Emissions
The Aral Sea sits between Kazakhstan and Uzbekistan and was once the fourth-largest inland body of water on Earth. For the past 60 years, though, humans have bled it nearly dry irrigating cotton crops, leaving behind a salty plain the size of Ireland. Its loss has long been seen as an ecological and humanitarian problem, but new research shows that it has also been a significant driver of climate change.
