I'm having a hard time figuring out if these guys are on the consensus side or not?

Hollywood has a thing for Al Gore and his three-alarm film on global warming, “An Inconvenient Truth,” which won an Academy Award for best documentary. So do many environmentalists, who praise him as a visionary, and many scientists, who laud him for raising public awareness of climate change.

Don J. Easterbrook, a geology professor, has cited “inaccuracies” in “An Inconvenient Truth.”

But part of his scientific audience is uneasy. In talks, articles and blog entries that have appeared since his film and accompanying book came out last year, these scientists argue that some of Mr. Gore’s central points are exaggerated and erroneous. They are alarmed, some say, at what they call his alarmism.

“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.

Other critics have zeroed in on Mr. Gore’s claim that the energy industry ran a “disinformation campaign” that produced false discord on global warming. The truth, he said, was that virtually all unbiased scientists agreed that humans were the main culprits. But Benny J. Peiser, a social anthropologist in Britain who runs the Cambridge-Conference Network, or CCNet, an Internet newsletter on climate change and natural disasters, challenged the claim of scientific consensus with examples of pointed disagreement.

“Hardly a week goes by,” Dr. Peiser said, “without a new research paper that questions part or even some basics of climate change theory,” including some reports that offer alternatives to human activity for global warming.

Geologists have documented age upon age of climate swings, and some charge Mr. Gore with ignoring such rhythms.
