Melting Arctic sea ice

You know, the global warming deniers claim with a perfectly straight face that there is more ice this year than last. I don't know where they get that information. Take a look at this from CNN:

OSLO, Norway (AP) -- Data showing Arctic sea ice may reach its lowest level on record this summer underscores the need for governments to speed up talks on a new climate pact, the Worldwide Fund for Nature said Monday.

The WWF said observations on ice coverage and thickness pointed toward a record low for the second year in a row, continuing a "catastrophic" trend that could threaten polar wildlife and accelerate global warming.

"If you take reduced ice thickness into account, there is probably less ice overall in the Arctic this year than in any other year since monitoring began," said Martin Sommerkorn, senior climate adviser of the WWF's Arctic program.

"This is also the first year that the Northwest Passage over the top of North America, and the Northeast Passage over the top of Russia, are both free of ice," he said.
"There are already signs that species such as polar bears are experiencing negative effects as climate change erodes the ice platform on which they rely," Sommerkorn said. "These changes are also affecting the peoples of the Arctic whose traditional livelihoods depend on healthy ecosystems."

Arctic ice melts in summer and refreezes in winter. But over the years, more of the ice is lost to the sea with less of it recovered in winter. While ice reflects the sun's heat, the open ocean absorbs more heat and the melting accelerates warming in other parts of the world.

When the news is mainstream enough to be picked up by AP and CNN, you know it can no longer be denied.

I wish this were seen by our politicians in both parties as the emergency situation it is.
