Greenland's Ice Sheet Is Slip-Sliding Away: The massive glaciers are deteriorating twice as fast as they were five years ago. If the ice thaws entirely, sea level would rise 21 feet.

Climate experts have started to worry that the ice cap is disappearing in ways that computer models had not predicted...

...By all accounts, the glaciers of Greenland are melting twice as fast as they were five years ago, even as the ice sheets of Antarctica — the world's largest reservoir of fresh water — also are shrinking, researchers at NASA's Jet Propulsion Laboratory and the University of Kansas reported in February...

...Should all of the ice sheet ever thaw, the meltwater could raise sea level 21 feet and swamp the world's coastal cities, home to a billion people. It would cause higher tides, generate more powerful storm surges and, by altering ocean currents, drastically disrupt the global climate...

...By 2005, Greenland was beginning to lose more ice volume than anyone expected — an annual loss of up to 52 cubic miles a year — according to more recent satellite gravity measurements released by JPL...

...The amount of freshwater ice dumped into the Atlantic Ocean has almost tripled in a decade...

...There was even a period of melting in December..."We have never seen that," ...

...Most of the computer models on which climate predictions are based did not take the dynamics of the glaciers into account...

...In all, 12 major outlet glaciers drain the ice sheet the way rivers drain a watershed, setting the pace of its release to the ocean. If they all slide too quickly, there is a possibility that, perhaps decades from now, they could collapse suddenly and release the entire ice sheet into the ocean...
