WASHINGTON - The Earth is the hottest it has been in at least 400 years, probably even longer. The , 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." Their 155-page report said average global surface temperatures in the Northern Hemisphere rose about 1 degree during the 20th century.




- Emissions of the greenhouse gas carbon dioxide, thought by most scientists to be a cause of global warming because it tends to trap the sun's heat near the Earth, rose 78 percent in Wisconsin from 1960 to 2001, according to a new analysis of government data by the Wisconsin Public Interest Research Group.
