Arctic sea ice could be gone by 2012

CNN reports on what a disastrous summer it has been for the warming of the Arctic.  From the article:

  • 552 billion tons of ice melted this summer from the Greenland ice sheet, according to preliminary satellite data to be released by NASA Wednesday. That’s 15 percent more than the annual average summer melt, beating 2005’s record.
  • A record amount of surface ice was lost over Greenland this year, 12 percent more than the previous worst year, 2005, according to data the University of Colorado released Monday. That’s nearly quadruple the amount that melted just 15 years ago. It’s an amount of water that could cover Washington, D.C., a half-mile deep, researchers calculated.
  • The surface area of summer sea ice floating in the Arctic Ocean this summer was nearly 23 percent below the previous record. The dwindling sea ice already has affected wildlife, with 6,000 walruses coming ashore in northwest Alaska in October for the first time in recorded history. Another first: the Northwest Passage was open to navigation.
  • Still to be released is NASA data showing the remaining Arctic sea ice to be unusually thin, another record. That makes it more likely to melt in future summers. Combining the shrinking area covered by sea ice with the new thinness of the remaining ice, scientists calculate that the overall volume of ice is half of 2004’s total.
  • Alaska’s frozen permafrost is warming, not quite thawing yet. But temperature measurements 66 feet deep in the frozen soil rose nearly four-tenths of a degree from 2006 to 2007, according to measurements from the University of Alaska. While that may not sound like much, “it’s very significant,” said University of Alaska professor Vladimir Romanovsky.

    1. There’s no such thing as global warming. Its just Chuck Norris turning up the sun because he was chilly.
