Probably no controversial subject involves more vested interest than that of global climate change. I've seen the (subsequently discredited) Channel 4 TV programme "The Great Global Warming Swindle" and I also have in my ever-increasing 'to read' pile the special issue of Skeptical Inquirer on global warming, as well as the issue of New Scientist covering the subject.
Then I read Stephen Fry's blog entry on the subject (impressing me enough to send a link to Josh Timonen at RichardDawkins.net). Stephen Fry's approach is of one who does not have the facts, but nevertheless is prepared to act on probabilities. His reference to Pascal's Wager was particularly neat. And one of the commenters, milkyman, posted a link to a video, which I embed below:
There's also a follow-up video (plus related videos on other aspects of the controversy):
