From Cato.org: In “Inconvenient Truths,” Patrick Michaels, Cato senior fellow in environmental studies, questions the science behind Gore’s film, calling it “a riveting work of science fiction.” He continues: “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.”
Riveting… if you can maintain suspension of disbelief. A difficult feat to accomplish if you have a reasoning mind, a modicum of science education, and have actually looked at some of the theories and evidence on climate change.
