Sadly

Meanwhile, arguments from deniers keep getting knocked down, to the point where one must conclude that there really are only two types of denier: those who are paid by industry to spread misinformation in attempts to confuse the public, which is criminal, and those who are unable to see the evidence staring them in the face and who still cling to arguments that one minute with Google would dispel, which is pathetic and stupid.

The latest blow to the deniers came when the U.S. Environmental Protection Agency examined in detail 10 petitions challenging its 2009 finding that climate change is endangering the planet, that it is largely caused by burning fossil fuels, and that it threatens human health and the environment.

In every case, the EPA found that the petitions misinterpreted data, contained outright false claims, and included exaggerated charges.

"The endangerment finding is based on years of science from the U.S. and around the world," said EPA administrator Lisa P. Jackson. "These petitions - based as they are on selectively edited, out-of-context data and a manufactured controversy - provide no evidence to undermine our determination. Excess greenhouse gases are a threat to our health and welfare."
