Scientists call it the Doomsday Glacier.
Part of this is the alarming melting of the glacier the size of British Twaits in West Antarctica: it is receding half a mile (2,625 feet) per year. Scientists estimate that all glaciers will be gone within 200 to 600 years. When that happens, the sea level will rise to 1.6-2 feet (0.5 meters).
But sea level rise doesn’t end there. Twitz’s nickname is mostly due to what happens after the crash.
Currently, glaciers act as a buffer between warmer seas and other glaciers. Its collapse could result in snowfall in neighboring West Antarctica. The operation will raise sea levels to about 10 feet and permanently flood many coastal areas, including New York City, Miami and the Netherlands.
“It’s a big change, changing the coast,” said David Holland, a professor of meteorology at New York University who is contributing research to the International Twitz Glacier collaboration. He told PBS Newshor in February.
This worm, two new studies add details to the scary picture. The research has been published in Last Week ice The warm ocean currents are found in the lower reaches of the Twaits Glacier can be destroyed.
Meanwhile, a study published on Monday used satellite imagery to show that parts of the tweets and the adjacent Pine Island Glacier are decaying faster than previously thought. Posted by Proceedings of the National Academy of Sciences.
The images below reveal what will happen to neighboring tweets and glaciers in the future as well.
Melting glaciers of Twaits and Pine Island is already about 5 percent of sea level rise.

It’s not just tweets: the melting of the Antarctic ice sheet is six times faster than it was in the 1980s. They drop 252 billion tons a year, up from 40 billion tons 40 years ago.
Scientists estimate sea level rise as the entire Antarctic ice sheet melts at an altitude of 200 feet (60 meters).
Pictures taken before and after the spacecraft show the eggs coalescing into the sea.
“The satellites show that a glacier is coming ashore,” said Ted Scampos, a senior scientist at the University of Colorado. He told NASA in February.
According to new research, this rapid melting is caused by the decomposition of the natural stores held by the eggs and pine glaciers.

Glaciers similar to those in the Pine Island Glacier image above form near the scissor edges of the glaciers: the areas where the fast-moving glaciers meet the ice or rocks, and what they contain.
new PNAS The scissor ends of the search at Pine Island and Twaits Glacier weaken and disintegrate, causing ice to flow into the ocean.
The loss of Twitz Glacier is deeply troubling, and the US and UK have set up an international agency to study it.
That organization, Twitz Glacier Cooperation International, is studying the glacier with icebreaker ships that can break thick ice sheets.
In February, researchers discovered a room the size of Manhattan at the bottom of the tweets.

The room, which NASA scientists discovered in 2019, can capture 14 billion tons of ice using ice penetrating radar.
The chart below shows how the glacier is moving under the warm warm water, which is slowly melting from the bottom.

As the ice sheets melt from below, they lose their structure, melt faster and disintegrate in the ocean, as Twaits do.
Researchers estimate that the Pine Island Glacier has lost the size of Los Angeles over the past six years.
“These are the first signs that the Pine Island Ice Shelf has disappeared,” said Steve Lhermitt, a satellite expert and lead author. PNAS Looking, happy Washington Post.
“This damage is difficult to heal.”
Sea level rise is expected to affect 800 million people by 2050, according to a 2018 report.
