Scientists call it the Day of Judgment Glacier.
This is partly because the UK-sized glacier Thaiites in West Antarctica are melting at an alarming rate: it is retreating about half a mile (2,625 feet) each year. Scientists estimate that glaciers will lose all their ice in about 200 to 600 years. When it does, it will Extend about 1.6-2 feet above sea level (0.5 m).
But sea level rise will not stop there. The nickname for thyroiditis is usually derived from what happens after it melts.
Currently, the glacier acts as a buffer between the warming ocean and other glaciers. Its collapse could cause the neighboring ice masses in West Antarctica to come down with it. In addition, the process will raise sea levels by about 10 feet, bringing many coastal areas permanently below New York City, Miami and the Netherlands.
“It’s a big change, rewriting the coast,” said David Holland, a professor of atmospheric science at New York University who contributes research to the International Thwaites Glacier Collaboration. In February, PBS News reported to Zahoor.
This worm, two new studies have linked the worrying picture in detail. The research was published in the Journal last week Crispier Got that The warm current of the ocean may be eating away at the undergrowth of the Thwaites Glacier.
A study published on Monday, meanwhile, Use Satellite Images To show that parts of the Thawites and neighboring Pine Island glaciers are breaking down faster than previously thought. That work was published Procedure of the National Academy of Sciences.
The pictures below show what’s happening to Thaiweats and nearby glaciers, as well as what might happen in the future.
The melting of the Thaiweats and Pine Island glaciers is already 5 percent of global sea level rise.
Above: Between October 2014 and May 2019, satellite imagery showed heavy damage to the Thai Whites and Pine Island glaciers.
It’s not just Thaiwites: it’s the Antarctic ice sheet Melt six times faster It was in the 1980s. It is flowing 252 billion tons a year, up from 40 billion tons a year 40 years ago.
If the entire Antarctic ice sheet melts, scientists estimate sea levels Will exceed 200 feet (60 m)
Photographs taken before and after space show the Thwaites Glacier melting into the ocean.
Ted Scambos, a senior scientist at the University of Colorado, said: “The satellite we are showing is a glacier that is splitting off the coast. Told NASA in February.
This rapid melting is partly due to new research showing that the natural buffers that hold thuvites and pine glaciers are breaking down.
Above: Crews near the grounding line of the Pine Island Glacier in Antarctica.
Creases, such as the Pine Island Glacier, form near the edge of the glaciers: the area where the fast-moving glacier meets the slow-moving ice or rock that holds it.
New PNAS the study Found that shear margins on the Pine Island and Thaiweats glaciers are weakening and breaking, which could lead to ice flow in the ocean.
The loss of the Thwaites Glacier is so alarming that the United States and the United Kingdom have set up an international agency to study it.
That organization, International Thwaites Glacier Support, Icebreakers study glaciers by ships that can break through dense ice sheets.
In February, researchers discovered a Manhattan-sized rock on the underside of the Thwaites.
Above: In West Antarctica, there is a cave about 1000 feet high at the bottom of the Thaiwats Glacier.
Cave that NASA scientists found In 2019, 14 billion tons of ice could be stored using snow radar.
The figure below shows how much hot water flows under the heater, slowly melting it from bottom to top.
Above: A 3D image of the Thaiweats Glacier shows seawater channels that can carry hot water to the bottom of the glacier and cause it to melt.
When the ice sheets melt underneath, They may lose their temper, Which will melt more quickly and break into the ocean, as the Thai whites are doing.
Researchers have estimated that the Pine Island Glacier has lost an area of Los Angeles in the last six years.
“These are the first signs we see the Pine Island ice shelf disappearing.” PNAS the study, Told The Washington Post.
“It’s hard to heal.”
According to a 2018 report, sea level rise could reach 800 million people by 2050.
Above: An estimate similar to the sea level in New York City with a 10 foot sea level rise.
Report, from C40 City Climate NetworkFound that sea level rise could threaten the power supply to 470 million people and regularly bring 1.6 billion people to extreme temperatures.
