NCPA - National Center for Policy Analysis


March 22, 2007

While former Vice President Al Gore did his best to limit his exposure while testifying at Congressional hearings, he cannot hide from the various mistakes, misstatements and outright falsehoods in his movie and books on global warming, says H. Sterling Burnett, senior fellow at the National Center for Policy Analysis.

There are several instances where Gore is out-of- step with science, says Burnett:

  • Gore implies that human-caused global warming is instigating a decline in the snow pack on Mount Kilimanjaro; however, according to studies in the International Journal of Climatology and the Journal of Geophysical Research, the retreat began in the late 19th century -- before most human greenhouse gases were emitted.
  • Gore also says that human-caused global warming poses a threat of extinction to polar bears; yet current polar bear numbers have increased dramatically, from around 5,000 polar bears in the mid- century to between 22,000 and 25,000 today.

Additionally, Gore has implied that in the near future global warming threatens to raise sea levels between 20 and 40 feet, swamping coastlines and creating 200 million refugees:

  • However, the 2007 Intergovernmental Panel on Climate Change (IPCC) report provides a high estimate of only 17 inches of sea level rise in the next century -- less than half its previous high estimate.
  • And a 2005 study in the Journal of Glaciology by a NASA scientist concludes the glacial loss is occurring slowly: 0.05 millimeters on average per year. At that rate, it will take a millennium for the oceans to rise 5 centimeters (roughly 2 inches) and 20,000 years to rise a full meter.
