That said, it would be more accurate to say, “It’s not only the heat, it’s also the humidity.” Based on a question about water vapor and global warming we recently received from a UCS supporter in Lexington, Kentucky, I talked with the lead author of our recent Killer Heat report, Kristina Dahl, a senior climate scientist in our Climate and Energy Program, about increasing heat and humidity, global warming, and the choices we face.

This new rule will result in less protection for America’s threatened wildlife and a higher likelihood of losing species forever as Earth’s sixth mass extinction occurs.  Read more >
