Al Gore’s Oscar winning documentary has to face an inconvenient truth of its own. Some scientists are calling his claims exaggerated and erroneous. According to today’s New York Times, there has been a backlash among some in the scientific community since the release of the film.
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.”. . .
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. . .
“Nowhere does Mr. Gore tell his audience that all of the phenomena that he describes fall within the natural range of environmental change on our planet,” Robert M. Carter, a marine geologist at James Cook University in Australia, said in a September blog. “Nor does he present any evidence that climate during the 20th century departed discernibly from its historical pattern of constant change.”
This story is significant, not only because it recognizes the range of opinions within the scientific community (which the film does not acknowledge), but also because it appears in The New York Times, of all places. No one will be able to argue that this story is propaganda campaign on the part of oil companies.
