For anyone really interested in actually learning something about this subject isatead of just yelling about it, I highly recommend Michael Chrichton's book "State of Fear". Just finished it and am more amazed/confused/appaled why more people are so wrong on this. He writes a fictional story (for those of you raised in government schools, that means he made it up) but woven around published facts by many different people and organizations. The story is made up, but all the facts, which he meticulously footnotes, are real. Just a graet read. At the end of the book he writes a little essay on why it can be sooo dangerous to accept popular thinking without anyone checking to see if in fact it is true. He cites a popular theory from a century ago. It was widely accepyed by such people as Thedore Roosevelt, Woodro Wilson, Alexander Grahm Bell, Margaret Sanger, H.G. Wells, and Oliver Wendell Holmes. The US supreme court agreed with it and many states across the land passed resolutions supporting it. Sound anything like global warming so far? That theory was eugenics. It postulated that the human gene pool was in danger of deteriation from immigrants and dysfunctional, uneducated people. It was a made up crisis that ultimately led to Germany killing millions of people to keep the race pure. And there was literally no science behind it. Just sounded like a good idea. Give the book a try, it's an easy read despite the length. I founs a copy on ebay that looked new and paid less than $8 with shipping. Or you could just bury your head in the sand and go to Al Gore concerts.
