Arctic tipping point.
September 2, 2008 1:58 AM

The ice is melting...fast:

The National Snow and Ice Data Center has reported that sea ice in the Arctic now covers about 2.03 million square miles. The lowest point since satellite measurements began in 1979 was 1.65 million square miles, last September.

With about three weeks left in the Arctic summer, this year could wind up breaking that record, scientists said.

Yikes!

And if that wasn't bad enough, we now have methane belching out of the arctic, too:

On top of that, researchers are investigating "alarming" reports in the last few days of the release of methane from long-frozen Arctic waters, possibly from the warming of the sea, said Bill Hare, a Greenpeace climate scientist, who was attending a climate conference in Ghana. Giant burps of methane, which is a potent greenhouse gas, is a long-feared effect of warming in the Arctic that would accelerate warming even more, according to scientists.

Indeed, the feedback loop might have reached the point of no return already:

"We could very well be in that quick slide downward in terms of passing a tipping point," said Mark Serreze, a senior scientist at the data center, in Boulder, Colo. "It's tipping now. We're seeing it happen now."

Five climate scientists, four of them specialists on the Arctic, told The Associated Press that it was fair to call what was happening in the Arctic a "tipping point."

Feeling warm and cozy?
