The length to which global warming naysayers must go to confuse the public should reveal how unanimous is the knowledge that man is causing global warming.

Willie Soon has no training in global warming.
This article is middle of the road, from my reading, and these quotes are revealing:

“I have not stood behind the paper by Soon and Baliunas,” Kinne said, according to the Times. “Indeed: the reviewers failed to detect methodological flaws.”

“Serious scientists will tell you over and over again that this was a deeply flawed study that should never have been published,” Mann said. “Scientifically this study was considered not even worthy of a response. But because it was used politically, to justify policy changes in the administration, people in my field felt they had to speak out.”

“My impression is that the critics are right,” said John Holdren, Heinz professor of environmental policy at the Kennedy School of Government. “It’s unfortunate that so much attention is paid to a flawed analysis, but that’s what happens when something happens to support the political climate in Washington.”

Professor Daniel Schrag of the Department of Earth and Planetary Sciences said that he did not think Soon and Baliunas’ approach to finding a global average temperature was as honest as other approaches.

“The bottom line is that this paper is suggesting that the unusually warm weather we’ve been having for the last 100 years is part of natural variability,” he said. “We have observations to show that that’s not the case.”

David Legates is even less qualified. His specialty is rainfall, not warming. His only significant paper on temperature was written more than 20 years ago. Some facts regarding his track record are here:

Just as cigarette companies argued cigarette were safe, and auto manufacturers argued against seat belts, companies prefer to avoid laws based on reducing global warming. That's their perogative, but we shouldn't let PR compaigns distract us from what is already known.
