The G8 are wealthy countries whose leaders feel that their citizens will put up with this lunacy. They continue to insist there is a scientific consensus that climate change is man-made. (They have to call it "climate change" now, since we are in a cooling trend these days.)
A group of eminent scientists beg to differ with the claim of consensus. Their statement can be found on the web site of the Cato Institute.
Fortunately, the majority of the G8 citizens have the common sense to laugh at this hooey. But they won't be laughing when the bills start coming in, straining already overtaxed economies.
Who will benefit from this sort of nonsense? A big beneficiary will be the Chicago Climate Exchange. Can you guess who founded this boondoggle? Would you believe it was Al Gore and Henry Paulson? That says it all, doesn't it?
