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.

According to Al Gore, the polar caps already melted about 10 years ago, so this is fake news.

Perhaps I’m not a scientist but doesn’t ice expand when it’s frozen and then takes up less volume when it melts, if that’s true why wouldn’t ocean levels go down instead of up if that glacier melts
I expect Osama and Brad Pitt to be selling their ocean side mansions immediately

Oh brother 🙄
What if I start to worry?!
If it breaks off, it will float.......
That glacier is on land. If it melts, it joins the ocean.
Floating ice has no effect on water level when it melts.

You are correct, but for a few problems. If I am not mistaken, the volume different is a few percent. It is not substantial. The main problem is that the glacier is currently mostly above the waterline, due to it’s connection to the antarctic continent. If it gets undermined and then falls in, 90%+ of it’s volume will be added to the sea (because ice has the higher volume, iceberg tips are above water due to buoyancy), and then as it melts all of the volume is added
Let me know when Obama sells his beachfront house, and the other elites stop flying their private planes. Until then, I am very confident that the climate change crisis is a fraud.
Evacuate Martha’s Vineyard, New York City, and Amsterdam before it’s too late.
If it breaks off, it will:
1) no longer be supported by land.
2) be driven into warmer waters where it will melt.
Land ice entering the ocean increases the amount of water in the ocean.
The earth is calculated to be only 0.5% water so what harm could a little extra water do? Just more fear porn.
