CATO’s Patrick J. Michaels, who has ably argued at NRO that the contribution to global warming of anthropogenic greenhouse gases is de minimus, is getting some love from Fox News, which reports on Michael’s speech to the Conference on Climate Change. Except this time, Michaels’ target isn’t the UN IPCC — it’s the EPA:

EPA scientists say manmade carbon dioxide and other greenhouse gases are contributing to a warming of the global climate — and as such represent a threat to human welfare. Officials went so far as to declare the gas a danger to mankind in early December. But a leading climatologist says his research indicates that CO2 poses no threat to human welfare at all, and he says the EPA should revisit its findings.
“There is an overestimation of the environment’s sensitivity to CO2,” said Dr. Patrick Michaels, senior fellow in environmental studies at the CATO Institute and a past president of the American Association of State Climatologists.
. . .Michaels described how the U.N. gathers weather information for its computer models, on which the EPA based its ruling. He said data gathering at weather stations in some parts of the world is spotty, and U.N. scientists add new figures to compensate. But in doing so, he said, they also add errors to the final research product.
“There is a systemic bias in the computer models,” said Michaels, whose research suggests that the U.N.’s adjusted computer modeling data, rather than actual observed data, is what connects the rise in temperatures to manmade causes. When one takes away the computerized modeling enhancements, he said, mankind’s contribution to global warming is virtually nil, approximately .03 degrees, rather than .07 degrees, over the last 50 years.
Thus, he said, most of the planet’s warming is not from manmade sources. “This idea that most of the warming is due to greenhouse gases caused by man just isn’t right,” he said.
