It was for a moment the clash of the Nobel Prize winners on climate change… just barely, but nothing like this has happened before in the debate-that-isn’t. Normally this is not a show the heavyweights turn up too. But there were three Nobel winners in the room at the same time.
Paul Crutzen, Mario Molina and Sherwood Rowland won the 1995 Nobel for work on Ozone. Both of the first two are fans of the man-made global warming theory and they both spoke just prior to notable skeptic Ivar Giaever (who won a Nobel for tunneling in superconductors in 1972). [UPDATE: Watch Giaever speak - the whole speech - it's excellent. h/t Roberto Soria]
As usual, the core arguments of believers comes down to argument from authority. Can they attack the credentials of the dissenters? The skeptics, the real scientists, talk about evidence.

“The scientific evidence is really overwhelming. Most experts agree; maybe two or three in 100 disagree.” He added, “I know who they are and why they are wrong.”
