This has been all over the blogosphere, but I had to mention it – John Coleman, founder of the Weather Channel, has written an article in which he calls the idea of man-made global warming ‘a scam’:

It is the greatest scam in history. I am amazed, appalled and highly offended by it. Global Warming; It is a SCAM. Some dastardly scientists with environmental and political motives manipulated long term scientific data to create in [sic] allusion of rapid global warming. Other scientists of the same environmental whacko type jumped into the circle to support and broaden the "research" to further enhance the totally slanted, bogus global warming claims.
