climate tipping points unveiled

PITTSBURGH— A new international study released today warns that ecosystems and societies are at risk from the ongoing warming of our planet.

The study, to be published in the Feb. 4-8 Proceedings of the National Academy of Sciences, Online Early Edition, outlines the most vulnerable areas of earth at risk for abrupt climate change, according to Elmar Kriegler, a visiting research scholar in the Department of Engineering and Public Policy at Carnegie Mellon University.

Kriegler, a researcher from the Potsdam Institute for Climate Impact Research in Germany, was one of seven scientists who helped to compile the study, drawing on the insights from a climate change workshop sponsored by the British Embassy in Berlin in October 2005, and an opinion survey of 52 experts in the field.
