Gore's reluctance to go toe-to-toe with global warming skeptics may have something to do with the - from the standpoint of climate change alarmists - unfortunate outcome of a global warming debate in New York last March. In the debate, a team of global warming skeptics composed of MIT scientist Richard Lindzen, University of London emeritus professor of biogeology Philip Stott, and physician-turned novelist/filmmaker Michael Crichton handily defeated a team of climate alarmists headed by NASA scientist Gavin Schmidt. Before the start of the nearly two-hour debate, the audience of several thousand polled 57.3 percent to 29.9 percent in favor of the proposition that global warming is a "crisis." At the end of the debate, the numbers had changed dramatically, with 46.2 percent favoring the skeptical point of view and 42.2 percent siding with the alarmists.
So after two hours of debate the numbers went from 57.3 to 29.9 for Global warming being a crisis to 46.2 to 42.2 against. No wonder they will not debate the issue.
By the way, Hillbilly White Trash has a good post up about the rest of the article, here.
