You're perfectly entitled to think that. Every time I turn on the TV I hear at the end of every report on it "...But some people don't believe blah blah". If you've arrived at this conclusion by actually looking at data and scientific reports, more power to you. But there's so many kiddies who watch a few youtube vids, read a few
blogs, see a flash cartoon developed by Exxon but made to look like grassroots activism against the global warming 'scam' (Similar to Sony's "all I want for Christmas campaign) and suddenly they're an authority on the subject and know more than the world's leading scientists and peer reviewed studies. From then on they think that by sticking it to the 'man' on global warming they're Che fucking Guevara.
Durkin, by the way, made the "Great Global Warming Swindle" documentary, with his merry gang of mentalists from Living Marxism magazine, which was duely gobbled up by everyone in spite of being unadulterated bollocks like his previous a films such as "GM food - if you have any reservations, you're a Nazi" "Environmentalists eat children" and "If you don't get silicon breast implants you're going to die of cancer" Indeed several of the scientists he showed as his supporters and voices of dissent amongst the egg-head community are now suing him and he's being hauled before the regulators again for telling naughty porkies.
The thing that gets me is how many people claim to be agreeing with each other on the matter when they're not actually agreeing at all. Some say CO2 doesn't cause global warming, some say it does but hardly any of it comes from man, some say the earth is heating cos of the sun, some that it's not heating at all. One of the global warming denier's biggest heros doesn't even believe in the greenhouse effect - which means non of us exist and we're floating around on a huge block of ice
(Edited to change my first sentence from meaning the exact opposite to what I was trying to say - it's been a long day)
