An Inconvenient Truth for Al Gore

At least he'll aways have his Oscar, even if his documentary isn't supported by the data:

"I don’t want to pick on Al Gore," Don J. Easterbrook, an emeritus professor of geology at Western Washington University, told hundreds of experts at the annual meeting of the Geological Society of America. "But there are a lot of inaccuracies in the statements we are seeing, and we have to temper that with real data."

Mr. Gore, in an e-mail exchange about the critics, said his work made "the most important and salient points" about climate change, if not "some nuances and distinctions" scientists might want. "The degree of scientific consensus on global warming has never been stronger," he said, adding, "I am trying to communicate the essence of it in the lay language that I understand."

Although Mr. Gore is not a scientist, he does rely heavily on the authority of science in "An Inconvenient Truth," which is why scientists are sensitive to its details and claims.

Criticisms of Mr. Gore have come not only from conservative groups and prominent skeptics of catastrophic warming, but also from rank-and-file scientists like Dr. Easterbook, who told his peers that he had no political ax to grind. A few see natural variation as more central to global warming than heat-trapping gases. Many appear to occupy a middle ground in the climate debate, seeing human activity as a serious threat but challenging what they call the extremism of both skeptics and zealots.

Kevin Vranes, a climatologist at the Center for Science and Technology Policy Research at the University of Colorado, said he sensed a growing backlash against exaggeration. While praising Mr. Gore for "getting the message out," Dr. Vranes questioned whether his presentations were "overselling our certainty about knowing the future."

Typically, the concern is not over the existence of climate change, or the idea that the human production of heat-trapping gases is partly or largely to blame for the globe's recent warming. The question is whether Mr. Gore has gone beyond the scientific evidence.

"He's a very polarizing figure in the science community," said Roger A. Pielke Jr., an environmental scientist who is a colleague of Dr. Vranes at the University of Colorado center. "Very quickly, these discussions turn from the issue to the person, and become a referendum on Mr. Gore."

Gore's fellow global warming co-religionists will most likely discount the attempt to inject actual science into the global warming debate. As we well know, science and faith do not always go hand-in-hand.
