Paris (AFP) - A rapidly melting glacier atop East Antarctica is on track to lift oceans at least two metres, and could soon pass a "tipping point" of no return, researchers said Wednesday.
To date, scientists have mostly worried about the Greenland and West Antarctic ice sheets as dangerous drivers of sea level rise.
But the new study, following up on earlier work by the same team, has identified a third major threat to hundreds of millions of people living in coastal areas around the world.
"I predict that before the end of the century the great global cities of our planet near the sea will have two- or three-metre (6.5 - 10 feet) high sea defences all around them," said Martin Siegert, co-director of the Grantham Institute and Department of Earth Science and Engineering at Imperial College London, and the study's senior author.
From the air, the contours of Totten Glacier -- roughly the size of France -- are invisible because the entire Antarctic continent is covered by a seamless, kilometres-thick blanket of snow and ice.

Doesn't hysterical emotion count for anything?
The article is referring to a glacier above ground, not an iceberg.
Yeah, I notice everytime I have a beverage full of ice, when it melts, my glass oveflows.../S
Temperatures over the last two thousand years
This makes your point pretty well.
Did Al Gore come up with this?
**** “There’s not enough ice and snow on this planet to raise the seas to that level even if it ALL melted..........” ****
And yet it is Humans to Blame! Piss poor Math, Models and they just can’t seem to frame the Apocalyptic Message correctly. When are we gonna get it RIGHT! (Algore is pissed at us all now)
Woo hoo! Surf’s up! Finally we get something besides 3 foot mush!
“Kill Ethanol to Save the Coastal Cities!”
The last anti-Ethanol candidate had his character assassinated and chased out of town. Ethanol is here to stay.
Of course.
FYI the imagined rise is to come from the rain and snow that the glacier will no longer capture as ice when it’s gone. IE: that rain and snow will go to raise the level of the seas instead of being captured as ice.
An abstract of the report is here: http://www.nature.com/ngeo/journal/v8/n4/full/ngeo2388.html
A reasonable abstract of the abstract is “... may be...could...if... if...could potentially...may...”
The part of the glacier that is in the ocean is taller than the water level. As long as this part of the glacier is resting on the bottom, any melting of the ice above the water line will raise the level of the ocean.
Furthermore as long as the glacier continues to flow into the ocean faster than new glacier is formed, the level of the ocean will rise.
If you keep adding ice to your drink faster than you drink the liquid, the drink will overflow.
No. But if take glass that is full to the brim and drop an ice cube in it will.
This is a glacier, not an iceberg. The glacier currently resides on land and is currently flowing toward the sea along with its burden of gravel, sand, and grit.
This is typical “sky is falling syndrome.” Nonsense. This crap is constantly thrown at us hoping it sticks, but there is never any follow up with regard to their doomsday prognostications. Nonsense.
this is great. i won’t have to drive that far to get to a nj beach
Maybe some that extra water will eventually help replenish that depleted ground water in western states.
Oh Noes!
Does that mean I'm drinking too fast?
Oh, Yeah...You're wrong.
[Check out how much of that significant ice is below versus how much is above the waterline, then reflect on displacement and on water's expanding when it freezes/contracting when it melts.]
Hahahah. The Dutch have lived with dikes higher than that
for years.
