Ocean water is pushing miles beneath Antarctica’s “Doomsday Glacier,” making it more vulnerable to melting than previously thought, according to new research which used radar data from space to perform an X-ray of the crucial glacier.
As the salty, relatively warm ocean water meets the ice, it’s causing “vigorous melting” underneath the glacier and could mean global sea level rise projections are being underestimated, according to the study published Monday in the Proceedings of the National Academy of Sciences.
The Thwaites Glacier in West Antarctica — nicknamed the “Doomsday Glacier” because its collapse could cause catastrophic sea level rise — is the world’s widest glacier and roughly the size of Florida. It’s also Antarctica’s most vulnerable and unstable glacier, in large part because the land on which it sits slopes downward, allowing ocean waters to eat away at its ice.
Thwaites, which already contributes 4% to global sea level rise, holds enough ice to raise sea levels by more than 2 feet. But because it also acts as a natural dam to the surrounding ice in West Antarctica, scientists have estimated its complete collapse could ultimately lead to around 10 feet of sea level rise — a catastrophe for the world’s coastal communities.

Which of the 4 propaganda techniques does this article use?
No, since ocean currents are what they are. Keep in mind that the ice shelf is constantly melting due to the ocean current that circles the continent and the warmer water is due to the undersea volcanoes......
CORRECT! Earth is a SELF-SUSTAINING system which, we as humans, simply have to ADJUST to, in order to continue to SURVIVE.
If sea levels rise, there would also be more area under water. This would produce more evaporation.
If temperatures rise, this would produce more evaporation.
Even if we suppose a huge chunk or the entire glacier plops into the ocean, it would seem that most, if not all, of this additional water would end up back in the atmosphere and/or back into glaciers. I don’t know enough to speculate on a time frame.
“Evacuate Martha’s Vineyard, New York City, and Amsterdam before it’s too late.”
I thought NYC had already been evacuated. They moved to the South.
The glacial ice that is lost is replenished by annual snow fall created from the atmospheric moisture from the evaporation of water in the oceans.
The claim now is that the Thwaites Glacier is shrinking due to global warming when the reality is that the continent of Antarctica only gets an average of 2 inches of precipitation each year. Antarctica is technically a desert, This is because the cold air simply can't hold much water.
CNN and Liberals need to put out an arrest warrant on Mother Nature. The nerve of her!
That statement alone makes this article BS.
There is no ocean water under the "doomsday Glacier" because it is land based. The only ice being affected is the ice shelf floating in the ocean at the edge of the glacier.
So, the oceans won’t be drinkable any time soon then? 😂👍
You are correct on all those statements.
Worry not. All fears of Global flooding will end with the first atomic bomb, Fist Moscow goes, then New York, London, Paris and Berlin. All this Climate change will vanish as we worry about Fallout and radiation poisoning. In US, Boston, Atlanta and Kansas City will be targeted—all banking centers.
Nope! But you can still use the pieces of glacier ice in your martinis.......Fill up before they're gone. LOL!
OMG OMG OMG we're all gonna die, OMG OMG, smh!
Silly ... there aren't enough people in Antarctica to make that happen. LOL
The usual incompetent reporting, this time by a leftwing European French major turned “climate journalist.”
Thanks. Good summary about the volcanic geothermal variable.
Thank you.
The beast is in Geneva. Don’t forget them.
