FORECAST: Uh-Oh!

Arctic Ice Florida
ABCNEWS: Scientists report that arctic ice the size of the state of Florida has melted in the last six days. In just the last six days, researchers say 69,000 square miles of Arctic ice has disappeared, roughly the size of the Sunshine State. Scientists say the rate of melting in 2007 has been unprecedented, and veteran ice researchers worry the Arctic is on track to be completely ice-free much earlier than previous research and climate models have suggested. “If you had asked me a few years ago about how fast the Arctic would be ice free in summer, I would have said somewhere between about 2070 and the turn of the century,” said scientist Mark Serreze, polar ice expert at the NSIDC. “My view has changed. I think that an ice-free Arctic as early as 2030 is not unreasonable.”

NEW YORK TIMES: Two-thirds of the world’s polar bears will disappear by 2050, even under moderate projections for shrinking summer sea ice caused by greenhouse gases in the atmosphere, government scientists reported yesterday. The finding is part of a year-long review of the effects of climate and ice changes on polar bears to help determine whether they should be protected under the Endangered Species Act. Scientists estimate the current polar bear population at 22,000.
