Heavyweights Weigh in on Global Warming

Ever wonder what climate change experts talk about when they get together? The blog Daily Kos gives you a chance to find out -- well, at least to “listen” in on a virtual roundtable discussion with three renowned climate scientists.

Daily Kos sat down for an online chat with Dr. Michael E. Mann, director of Penn State’s Earth System Science Center; Dr. Gavin Schmidt, a climate modeler with NASA’s Goddard Institute for Space Studies in New York; and Dr. Stefan Rahmstorf, an oceanographer with the Potsdam Institute for Climate Impact Research.

The three are some of the minds behind the climate change blog RealClimate, on which experts weigh in on various climate news and myths that surface in the media.

The roundtable discussion deals with various matters related to our changing climate, including how quickly it’s changing, how we know human activity is having an impact, why you can’t blame climate change for isolated weather events, and what -- if anything -- can be done to lessen the impacts of global warming.
