Other than the fact that the temperature never rises into positive F... phew, that was close.

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.

The small and medium sized lies weren’t working.
Actually, when floating ice melts, it shrinks in volume to equal the volume it displaces, so no change to sea level.
Good point. I'm by no means a glacier expert, but simply did a little research and some math to see if the 10 foot claim was reasonable, which it isn't. There's a link to source in the original post. I assumed that this was ice over land, but that's a good point that any ice melting over water would actually lower sea levels.
I did a quick study and found that the sea levels could rise 24 feet, but only if all land ice measurements were accurate and if all the ice melted. Since most ice is in areas below -40°, there is no way the Earth would warm such that that ice would melt (not even by liberal nonsense claims), I ain’t worried.
Isn’t most of the mass of a glacier/ice berg-thingy under the water? Hasn’t that mass displaced as much mass as it can, already?
I’m thinking I learned about this in science class (back when it was actually TAUGHT) watching an ice cube melt in a glass of water.
But, what do I know? I’m no LibTard, so I ain’t a-smart!

Looked at from the viewpoint of historical geology, the oceans have risen and fallen countless times over the eons due to entirely natural causes. No humans were around to cause "tipping points" or the results therefrom. It can and will happen again.
This whole scam, and it's a huge one, is based on fear tactics promoted by intellectually dishonest academics and politicians who are taking advantage of the ignorance of the public at large about the time scales involved and what's happened to the Earth over geologic time.
The politicians and their greedy cronies like Al Gore are doing it for personal gain. I really don't understand the motives of so-called "scientists" like this one who must (or should) know that CO2 is not the cause of the Earth's periodic warming trends. It has been carefully documented by real scientists that increases in atmospheric CO2 happen hundreds of years after warming begins.
Nah, this will not happen instantly, but slowly enough to allow more building in higher parts of some coastal cities. Manhattan may be toast, but further north there are uplands to build on. Also the Palisades cliffs on NJ are well above sea levels subject to major melt. In DC the Mall may be toast, but much of the city is well above sea level. On the other hand places like New Orleans and Miami are in deep doo doo. These are cities that I have traveled in, others may also fit that pattern.
If enough “blue city” people move inland, they will no doubt convert some of the red or purple states back to blue.
since the Arctic worries proved baseless, the worrying has switched to the far south
Cool! Ocean front property in Vermont!
If you fill it with ice that is twice the height of the glass, then yes it would. All the ice in the world is not even with "the top of the glass."
Of course adding to the sea rise of 4.5 ft prior 2003 (Al Gore)......ohhhh wait!!
The loss of volume does not mean the ice is melting. It is a well known process called sublimation by which glacier ice goes directly to vapor, without turning first to water. Since Antarctica’s average temperature is well below freezing, even warming its temperature by an astounding 40 degrees wouldn’t make the temperature warm enough to melt ice.
um.... I doubt it.
The author needs to do a little elementary math.
The volume of the glacier is not equal to the volume of 2 meters of water across the oceans.
maybe 2 thousands of a MM
PLEASE let’s all stop using the ‘red’ ‘blue’ colors for Dems and Republicans.
If anything, the Dems should be commie RED
The Washington area badlands are a pretty freaky area of the country- and hard to comprehend the enormity of what must have happened.
My guess is a meteor hitting water, but not sure why it only affected Washington, unless it manages to hit some blocked up huge reservoir of water (but where was THAT stored..???)
There are whole cities that are now submerged- so something must have raised sea levels in the past
And prehistoric man used to hunt caribou on the floor of the once dry lake Huron as evidenced by hunting lanes and blinds discovered by scuba divers.........
