Scientists have raised concerns about a large, rapidly thinning glacier in Antarctica, warning it could contribute significantly to rising sea levels.
They say they've discovered two openings that could channel warm seawater to the base of the huge Totten Glacier and bring the threat of potentially disastrous melting.
The glacier is bigger and thinning faster than all the others in East Antarctica.
It contains enough ice to raise the global sea level by at least 11 feet (3.4 meters), according to researchers from the University of Texas at Austin who were among the authors of a new study published this week in the journal Nature Geoscience.
Scientists had previously detected warm water on the seaward side of the glacier. But until now, they had found no evidence that it could threaten coastal ice.
"We now know there are avenues for the warmest waters in East Antarctica to access the most sensitive areas of Totten Glacier," said Jamin Greenbaum, a University of Texas Ph.D. candidate and the lead author of the study....

“But who is to regulate Polar Bear BBQs of pengiuns?”
I surely hope the Polar Bears use solar heat based BBQs or they’ll be in big trouble with Algore.
President U.S. Grant said that Venice would be quite livable “if drained”.
What a bunch of crap.
I’d suggest reading Kabloona.
Some guy with a made-up name who hasn't even earned his degree yet is the lead author. Right.
Want to bet that liberals in government suddenly stop blaming fossil fuels once their nifty rides are taken away?
Raise the sea level by 11 feet??? Preposterous! Do these clowns have any idea how large the sea area is, and how to do simple arithmetic?
I’m rooting for a 230 foot rise. That will give me prime seashore property.
>>>But who is to regulate Polar Bear BBQs of pengiuns?<<<
The problem lies with all the CO2 that will be produced when we have to Fly all the Polar Bears from their Home in the Arctic to the Antarctic where the Penguins live.
Do you suppose Obama will let them use AF1?
I’m sure the first wookie would like to açompamy the first illegal immigrants.
“I’d suggest reading Kabloona.”
I’ll put it on the list after the other 17 books I want to read. Another 17 books may sneak into the list above Kabloona.
More glo-baloney...
This tripped my bogometer. Let's do the back-of-the-envelope calculation here...
Surface area of the world's oceans: 357,000,000 km^2.
What is the volume of the Totten Glacier? Wikipedia claims it is 538,000 km^2 (which seems high to me, but let's use it anyway). Assume 5.38x10^5. Ratio is 664-to-1. So to raise the ocean by 3.4 meters would require that the glacier be at least 664*3.4 = 2,250 meters deep. Actually since ice is only 91% as dense as water the glacier needs to be 2473 meters high.
And this glacier must somehow melt completely and all of that melt must somehow get dumped into the ocean (forgetting whatever ridges or mountain ranges are in the way.) And remember it needs to be subtracted from the height of the crust underneath it that is itself already well above sea level.
The article is bullshit.

I'd wager that even a 2 degree over a century rise in temperatures wouldn't make a friggin DENT in the Antarctic.
Now if you took a thousand degree blowtorch to Antarctica, we'd have something to talk about.
But that won't happen until the sun turns red giant.
In about a billion years.
They should charter a ship to study it later this year. When it gets iced in this time, they should not be rescued.
Umm... Isn’t that the one with the volcano under it??
No need to read further. Austin is the Berkeley of Texas. It doesn't get any more socialist.
