Panel: Warming will end some species

From the micro to the macro, from plankton in the oceans to polar bears in the far north and seals in the far south, global warming has begun changing life on Earth, international scientists will report next Friday.

“Changes in climate are now affecting physical and biological systems on every continent,” says a draft obtained by The Associated Press of a report on warming’s impacts, to be issued by the Intergovernmental Panel on Climate Change (IPCC), the authoritative U.N. network of 2,000 scientists and more than 100 governments.
