OSLO (Reuters) - Part of East Antarctica is more vulnerable than expected to a thaw that could trigger an unstoppable slide of ice into the ocean and raise world sea levels for thousands of years, a study showed on Sunday.
The Wilkes Basin in East Antarctica, stretching more than 1,000 km (600 miles) inland, has enough ice to raise sea levels by 3 to 4 meters (10-13 feet) if it were to melt as an effect of global warming, the report said.
The Wilkes is vulnerable because it is held in place by a small rim of ice, resting on bedrock below sea level by the coast of the frozen continent. That "ice plug" might melt away in coming centuries if ocean waters warm up.
"East Antarctica's Wilkes Basin is like a bottle on a slant. Once uncorked, it empties out," Matthias Mengel of the Potsdam Institute for Climate Impact Research, lead author of the study in the journal Nature Climate Change, said in a statement.
Co-author Anders Levermann, also at Potsdam in Germany, told Reuters the main finding was that the ice flow would be irreversible, if set in motion. He said there was still time to limit warming to levels to keep the ice plug in place.
Almost 200 governments have promised to work out a U.N. deal by the end of 2015 to curb increasing emissions of man-made greenhouse gases that a U.N. panel says will cause more droughts, heatwaves, downpours and rising sea levels.

THE SKY IS FALLING, THE SKY IS FALLING, BUUUUUCCK BUUUCCK, BUCK.
Bull$!t. Even if true, there ain't enough ice on the planet to do that. Square area of ice (ave. thickness out of water)spread over the entire square area of ocean?
Exactly!
Those luxury Alaskan cruises would have nothing to offer if glaciers didn't break apart into the ocean.
As they have for...THOUSANDS of years.
Sometimes I swear that environmentalists are "young earthers".
The only way we’re ever going to stop global warming/cooling/climate change is if we all send a bunch of money to the envirowackos.
Shit smells exotic and perfume stinks!
the weight of new snow is going to make all the ice fall into the sea!
These jerks couldn’t sell a used car!
If and might strike again. Good grief.
How much melting in Antartica is due to volcanic activity???
Earthquakes deep below West Antarctica reveal an active volcano hidden beneath the massive ice sheet, researchers said today (Nov. 17) in a study published in the journal Nature Geoscience
he discovery finally confirms long-held suspicions of volcanic activity concealed by the vast West Antarctic Ice Sheet. Several volcanoes poke up along the Antarctic coast and its offshore islands, such as Mount Erebus, but this is the first time anyone has caught magma in action far from the coast.
“This is really the golden age of discovery of the Antarctic continent,” said Richard Aster, a co-author of the study and a seismologist at Colorado State University. “I think there’s no question that there are more volcanic surprises beneath the ice.”

No one has explained to me what caused the end of last ice age! It requires lot of warming to melt many miles thick glaciers parked in the mid-west. So much ice melted it caused formation of the Great Lakes, largest body of fresh water on earth.
May be the cave man burned too many twigs?
“if it were to melt”
A big if. Two can play this game: “if Antarctica were to accumulate land ice more than melts elsewhere, it could lead to a dangerous drop in ocean levels.”
As with so many other claims of AGW, the “settled science” of Antarctica losing land ice has been proven false; see:
This almost has to be the case. It is well known that the continent has more sea ice (which poses some of its own risks, since sea ice will calve). From where does the sea ice come? It come from land ice moving into the sea. Climatologists invoked all kinds of special explanations to argue simultaneously that Antarctica was gaining sea ice while losing land ice. In hindsight, no special explanations are necessary. It is both gaining sea ice and gaining or at least not losing land ice.
Because it is in the eastern hemisphere. I looked at a map.
Don’t do the math. This is more important globally.
Do the math says Al when looking at the bank balance.
No dragons, plagues of locusts, or raining frogs? Given our other problems, I’ve really got my plate full, so I’m not going to “sweat” (so to speak) this.
People laugh when I tell them that Antarctica is the largest desert on earth.
By definition it is, because it gets virtually NO precipitation. And hasn't for countless millennia.
Unless...GOD put it there! Ooooh...
Again I think that environwhackos HAVE to be "young earthers".
If Antarctica losing ice is a "BIG f'ing deal", then earth can't be THAT old.
No, it took a lot of food to keep the Flintmobile going; being made of hardwood and stone, it was quite heavy; and there was a darned good reason other than the technological challenge that the Flintstones’ house didn’t have any glass in the windows, if you know what I mean.
That “greenhouse gas” had to go somewhere.
“Has anyone considered the possibility that this might cause Antarctica to capsize?”
This is why it is basically uninhabited, and few even visit there. You put too many people on it and - there you go, tipped right over.
FUD- fear uncertainty doubt. The climate change mantra
