Global Warming Worse Than We Thought

It may seem like every war waged by George W. Bush has been a prolonged disaster, but there is one war he wages that is going extremely well and is ahead of schedule: The War on Ice.

Arctic ice cap melting 30 years ahead of forecast

WASHINGTON --The Arctic ice cap is melting much faster than expected and is now about 30 years ahead of predictions made by the Intergovernmental Panel on Climate Change, a U.S. ice expert said Tuesday.

This means the ocean at the top of the world could be free or nearly free of summer ice by 2020, three decades sooner than the global panel's gloomiest forecast of 2050.

No ice on the Arctic Ocean during summer would be a major spur to global warming, said Ted Scambos, a glaciologist at the National Snow and Ice Center in Colorado.

"Right now ... the Arctic helps keep the Earth cool," Scambos said in a telephone interview. "Without that Arctic ice, or with much less of it, the Earth will warm much faster."

That is because the ice reflects light and heat; when it is gone, the much darker land or sea will absorb more light and heat, making it more difficult for the planet to cool down, even in winter, he said.
