Richard Alley: what we know now…

By Gareth Renowden 07/07/2013


In this talk, recorded at the American Geophysical Union’s Chapman Conference on Climate Communication in Colorado recently, Richard Alley gives his overview of what we know about the state of the climate. As you might expect, he covers the cryosphere in some detail (why Greenland may not be as big a worry as West Antarctica), but he also has interesting things to say about climate sensitivity (same as it ever was), food production, and the possibility that chunks of the planet may become too hot for humans. Well worth watching…

Check out the other talks from the conference, all up at the AGU’s Youtube channel. I’m planning to catch up with the talks by Mike Mann, Steve Lewandowsky, Jeff Masters and Gavin Schmidt — when I can find the time.
