One thing I find interesting about the Global Warming debate is that most people have fallen for the idea that the sceptics have a large financial interest in stopping action on global warming. Actually the reverse is true, with the large financial interest being with he proponents of global warming. Al Gore has made a lot from the global warming gig. He has made more money than Clinton has since they left the White House, and Clinton has made over $100 million. Here is an article that discusses this.
