John Walsh is a bona fide climate scientist from the University of Alaska--Fairbanks, he helped to write the Arctic Climate Impact Assessment for the International Arctic Council which was much in the news late last year, and he's a global warming skeptic. After saying that the warming we see might still be the result of natural variation, he admits that the evidence is building up that humans are part of the cause of global warming. While not convinced, he says at the very end of this interview that the prudent thing to do would be to reduce greenhouse gas emissions now.
If this is what a self-styled skeptic who is a genuine climate scientist thinks, what are we waiting for?
