Here are two good links for better understanding of climate issues.
The first is a discussion/debate between two well-credentialed climate scientists: John Christy of the University of Alabama and Kerry Emanuel of MIT.
Christy takes what I would characterize as a “rational conservative” view, sufficiently consistent with the more rational parts ofthe Republican mainstream that he’s frequently called to testify before Congress. Emanuel, who says he has been a lifelong Republican has broken with the party over climate. He takes what I would characterize as a “rational liberal” view–very different from the Democrats–and the Republicans.
The second is a talk given by Kerry Emanuel at the MIT Club of California, elaborating his view of “What We KNOW About Climate Change.”
