Study Says Earth’s Temp at 400-Year High
The Associated Press reports here at the Washington Post website: "The Earth is the hottest it has been in at least 400 years, probably even longer. The National Academy of Sciences, reaching that conclusion in a broad review of scientific work requested by Congress, reported Thursday that the "recent warmth is unprecedented for at least the last 400 years and potentially the last several millennia." A panel of top climate scientists told lawmakers that the Earth is running a fever and that "human activities are responsible for much of the recent warming.""
