Flaws in a report issued in 2007 by the U.N. Intergovernmental Panel on Climate Change are bringing into question the report's projections. Errors range from typos in key dates to sloppy sourcing. In the report, scientists even overstated how much of the Netherlands was below sea level. These flaws are serious enough that environmentalists could end up focusing more on the old question of proving that climate change is a threat, instead of the new question of how to stop it.
U.S. Senators James Inhofe, R-Okla., and John Barrasso, R-Wyo., believe the errors are reason enough to block mandatory limits on greenhouse gas emissions. Barrasso would even like to see an independent probe into the IPCC report, suggesting that the United States should halt any action on climate until it verifies the panel's scientific conclusions.
The ramifications of the IPCC report are spread far and wide, most notably to the Environmental Protection Agency's finding that greenhouse gases from mobile sources endanger public health and welfare. A coalition of conservative groups has filed a petition to overturn the EPA's finding on the same grounds.
