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.
Geologically, however, it is a distinct -- and volatile -- beast.

Say good bye to southern Florida, LA and Boston. This is quite concerning.
Man, you idiots just hate science.
I predict before the end of the century.......blah blah blah. This is science?

O.M.G!!!!

Well, it is melting into the ocean and the job of the scientist is to predict what it will do in the future. So yes, it is science.
Not everything in science is the here and now....
"These are issues that we have to resolve in our society today," he said by phone. "They are pressing right now."
The problem is that science is unable to say when that might happen -- or if it has happened already.
I am not a quasi scientitist, but the predictions of gloom and doom haven't happened so far. None of us will be alive in 80 years to prove or disprove. Technology might learn to stabilize the glacier. There was no sat image for 50 years ago so you can't prove it will or prove it won't. On top of that it has melted before and sea level has risen 40 feet. Man will adjust if nukes don't wipe civilization out first. I just do t understand why you all are getting all up in arms about an unprovable hypothetical, talk about idiotic.

What is the volume of Totten Glacier in liquid state?Man, you idiots just hate science.
How does a scientist observing a ice sheet = hating science? You're the one that hates science that wants it all to be defunded and won't Publish a fucking paper in a journal to show where or how this is wrong to begin with.
What is the volume of Totten Glacier in liquid state?
What is the volume of the oceans?
What is the volume of undersea volcanic land mass gained annually?
What is the annual undersea land mass change due to plate tectonics?
If you can't answer any of these questions without looking them up, you're just an unscientific lemming stooge who parrots BS.
