For more than a decade, the federal government has been putting out national assessments to indicate what effects global warming will have on the U.S. But according to noted climate scientist Dr. Patrick Michaels writing for, these assessments have been terribly biased, and the latest is worst of all. In 2002, the first assessment chose out of dozens of available models only two which showed the greatest change in temperature and precipitation. Both proved wrong. The latest report provides no context or background for its predictions, but on the encouraging side, shows precipitation increase taking place in spring, which is good for farmers, with year-round precipitation change still nearly three centuries away!
