Via Hit & Run, a Harris Interactive poll of climate scientists:
A slight majority (54%) believe the warming measured over the last 100 years is not "within the range of natural temperature fluctuation."... Based on current trends, 41% of scientists believe global climate change will pose a very great danger to the earth in the next 50 to 100 years, compared to 13% who see relatively little danger. Another 44% rate climate change as moderately dangerous.
In addition, "84 percent believe that man-made global warming is occurring." Color me unimpressed. If 16 percent don't believe man-made global warming is occurring--that's a minority, but hardly a lunatic fringe. Sort of like thinking John Edwards would make a good a president, except with a chance you might be proved right. And what about the degree of confidence? Only 74 percent believe there is actual evidence of man-made global warming, which leaves 10 percent who take it as an article of faith--not very reassuring. Bottom line: more than a quarter of all scientists don't see any conclusive evidence of man-made warming, which leaves us well short of anything that might reasonably be called a scientific consensus.
