AGW zealots = sane person
Climate change denier = will believe any fairy tale that makes them feel better
From what I see both online and from a few personal contacts it seems to me that the people who like to assume that global warming is simply a conspiracy also buy into many of the other ones going around: Obama wasn't born in the US, George Bush brought down the Twin Towers, nobody was shot in Orlando, the Illuminati, Aliens are contacting us, the moon landing was faked, and on and on. Is that because their lives are boring or is paranoia something that exists in DNA and so they can't help it? Lets hope they remain a minority.
