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.

Study paid for by Al Gore...
Sounds like the only thing likely to avert certain environmental disaster is more government spending.
Just shows you that creativity in literature has not been lost ... unfortunately, creativity in scientific literature is not all that desirable.... facts, just the facts.
Which explains why Antarctica is currently seeing the highest ice areas in the satellite era.
Because it’s getting WARMER.
U.N.’s Ban urges climate action ahead of New York summit
ABU DHABI (Reuters) - U.N. Secretary General Ban Ki-moon said on Sunday he was hopeful that a goal of limiting global temperature rises to a maximum 2 degrees Celsius could be achieved, but urged governments to take practical action before it was too late.
“We have to ask the leaders to commit to bold ambitious targets and we will ask them to accelerate their actions on the ground,” Ban told a two-day conference on climate change in the United Arab Emirates capital Abu Dhabi.
Ban said both meetings would be “solution shops” for an urgent problem.

Now I’m really worried.
BTW. How does one determine east/west in Antarctica anyway?
They really proved we have absolutely nothing to worry about.
If ice can get you in summer, imagine what winter must be like in Antarctica.
Glad that the whole global warming theory was discredited by those researchers.
They put all of our minds at ease with their excellent work.
Of course it’s at risk, we can’t have it any other way.
I know how we can save it though, don’t fear folks. We all need to drive with our seatbelts off, eat McDonalds everyday, look down the barrels of our guns to make sure they’re not loaded etc, you get the idea. After all that, then the earth utopia will be here, and all the ice will be saved!
I’d say something to the effect of how stupid can these people be that write these things, but I fear I already know the answer.
And change is the only constant with climate.
The Lear jet leftists expect to form the core of the global Green Inner Party. There they will continue to enjoy the finest foods and most advanced gadgets the world has to offer — while deciding your fate for you.
If you work very hard and show them your unwavering loyalty you may be permitted to join the global Green Outer Party. You will be allowed occasional servings of meat - and air conditioning on a rationed basis.
The rest of us will eat insects and swelter — for the good of the planet.
Al Gore didn’t pay for it..most likely it was paid by us....the US taxpayers.
If only there was an ice plug large enough to plug the pieholes of these charlatans!
I always panic when there's an "if" and "could" in the same sentence
By longitudinal degrees.
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?
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.”
Sorry, usually post links.
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
“The sky is falling” alert.
“Id say something to the effect of how stupid can these people be that write these things, but I fear I already know the answer.”
Ping to #31.
It is already happening!
Don’t these people have something useful to do?
At the south pole every direction is north.
First, odd that this has never happened before, even in other warming time periods.
Second, it’s funny that even when we just compare the left’s failed guesses, they were looking at the WRONG pole, telling us the danger was the arctic melting, when it turned out the danger was from the south.
Third, I’d like to see at least one billionaire global warming alarmist put their money where their propaganda is, and buy out “beachfront” property 400 feet above sea level. Seems like a sure long-term bet for them.
Trying to get my head around the concept of “East Antarctica” .....
Climate change is 5 Billion years old. Earth temperature have never been constant. That is why we had ice ages every so many thousand years in regularity followed by global warming.
It is egotistical to think man can change earth’s natural cycles. From orbiting satellites only a couple of hundred miles above no man made objects are visible! Only the great wall of China shows up as a barely discernible thin wiggly line.
