From a "senior fellow in environmental studies at the Cato Institute" we get this: Patrick J. Michaels on An Inconvenient Truth on National Review Online,
This Sunday, Al Gore will probably win an Academy Award for his global-warming documentary An Inconvenient Truth, a riveting work of science fiction.Except that the UN report specifically said they were leaving out a prediction of how much sea levels would rise from melting polar ice because they could not be precise,
The main point of the movie is that, unless we do something very serious, very soon about carbon dioxide emissions, much of Greenland’s 630,000 cubic miles of ice is going to fall into the ocean, raising sea levels over twenty feet by the year 2100.
Where’s the scientific support for this claim? Certainly not in the recent Policymaker’s Summary from the United Nations’ much anticipated compendium on climate change. Under the U.N. Intergovernmental Panel on Climate Change’s medium-range emission scenario for greenhouse gases, a rise in sea level of between 8 and 17 inches is predicted by 2100. Gore’s film exaggerates the rise by about 2,000 percent.
The panel said that because there is no scientific consensus about how fast ice in the Arctic and Antarctic are melting, its estimates of sea-level rise are based only on the fact that ocean water expands when it warms.A follow-up UN report says there is a 50% chance that the melting ice will raise sea levels by 13-20 FEET.
