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.

” their aggregated volume “
Mass
“If fills up the same volume that it displaced.
Think of a glass full of ice, topped off to the rim with water.
When the ice fully melts, there is no increase in the water in the glass. The level stays the same.”
Correct. Only with a glacier it is like adding more ice cubes to that glass.
Why??
Maybe it will wash away Zuckerberg’s Island Paradise that he’s stealing from native Hawaiians.
Zzzzzzzzz
Does the sun burnout happen all at once or over the 5,000,000,000 years does it deteriorate to a lower power and then burnout?
Asking for a friend!
Meltiing ice results in no change in water level.
That is true. However, glaciers only grow from the accumulation of snowfall which comes from the constant evaporation of the water in the oceans.
For what it's worth, there are now approx. 138 undersea volcanoes along the western Antarctica with the undersea current which warms the water surrounding the continent..
All three equally along with all the other interconnected seas according to Pascal's Law (water seeks its own level)
Oh, noes!! \o/
Chode is on it. Already posted omg guys 😂
We may still need to Oh, noes! guys to chime in.
This is series.
Water hanging out around ice. Who knew!!!!
“…which used radar data from space to perform an X-ray of the crucial glacier”
I’m not daft, but this sounds like the writer is completely retarded.
The false teachers playing with vulnerable minds. Again. Like they do every day.
Big Media reporters are among the least intelligent and least informed people you'll ever meet. Newsreaders are a step below them.
Whether it does down or stays the same, a massive floating iceberg is not going to affect the sea levels around the world flooding coastlines and islands everywhere.
Even if it went up, how much water would it take to raise the water level of the oceans all over the world, it would be unfathomable amount of water.
Unless it raises the sea level 550 feet, I don’t care.
I predict there will be numerous terrorist attacks in the US before Obama’s waterfront mansions are flooded.
