Thwaites Glacier also called the Doomsday Glacier, is a wide and tremendous Antarctic ice sheet streaming into Pine Island Bay, on the Walgreen Coast of Marie Byrd Land.
In the Weddell Sea, Twenty years back, 500 billion tonnes of ice sheets dramatically collapsed and shattered into many icebergs.

Hardest Change To Accept
One of the hardest things about a climate concern is that significant differences can happen soon. In 2019, I boarded Nathaniel B. Palmer, a 308-foot-long scientific research vessel that sailed the Thwaites Glacier ( Doomsday glacier) in Antarctica. We were floating in the clear waters in front of the glacier one day. The next day, we were wrapped by huge icebergs about the size of an aircraft.
Larsen Ice Shelf Melting
The 3,250-square-kilometer Larsen Ice Shelf was known to melt quickly, but no one predicted that a 200-meter-thick giant would take only a month to collapse totally. Glacier scholars were shocked by both the speed and extent of the collapse.
Meeting Of American Geophysical Union
A satellite image taken last month and presented by researchers at the American Geophysical Union’s annual meeting on Monday is an important ice shelf that holds the West Antarctica Thwaites Glacier together (important protection against global sea-level rise). Suggests that it is within the next three years. The Thwaites Glacier in Antarctica is known as the “Terminal Glacier” because it poses a danger during the melting process. It throws billions of tons of frost into the ocean, and its collapse can cause irreversible shifts throughout the globe.
Size Of Glacier
Glaciers as large as Florida and the United Kingdom have already contributed about 4% to global sea-level rise, losing about 50 billion tonnes of ice each year and being extremely weak to climate crises. The fall of ice shelves can threaten the collapse of significant Antarctic glaciers.
Other Unstable Glaciers
Ice shelves (think of them as floating extensions of the Thwaites Glacier) are several ice shelves that scientists closely monitor in the Amunzen Basin, West Antarctica. Some ice shelves, including the Site and the Pine Island Glacier next to it that hold the glacier there, are being eroded by rising seawater temperatures.
Warm seawater can weaken these floating ice shelves and the fuel that melts from below, thinning and weakening the ice and creating the cracks and crevices found on the surface.
Researches On Cracks On The Thwaites Ice Shelf
- Expert supports the research which was published in 2020, according to that report the development of crevices and cracks in the Thwaites glacier.
- These show structural weakening.
- This damage can boost the feedback effect, as crevices and cracks can additionally debilitate and allow the ice shelves to collapse quickly.
- Other studies suggest that destabilizing the ice shelves and glaciers may not have dire consequences.
- Collapsed ice bergs and sea ice and blocks separated from glaciers have the same inhibitory effect as entire ice shelves, sandwiching chain reactions between buds and controlling the ongoing collapse of the whole West Antarctic Ice Sheet.
- However, while there are uncertainties about exactly what will happen in West Antarctica, one thing is certain.
- That is, the retreating Thwaites Glacier will raise the world’s sea level over the years to come.
Complete Damage In Coming Years
The ice split oceanographer saw was not an odd occasion. About half a month back, researchers took part in the International Thwaites Glacier Collaboration program between the U.K Natural Environment Research Council and the U.S. National Science Foundation. They have Introduced their most recent research. They explained the breaks and crevices in the Thwaites eastern ice rack, foreseeing that this ice shelf could crack just like the broken car window in the coming four to five years. “It won’t spread to the ocean as fast as it looks,” said Erin Pettit, a glaciologist at Oregon State University and one of ITGC’s principal investigators. “But the basic process is the same. Tense shelves have collapsed and can disappear within ten years. ”
Increase In The Sea Level
“The most worrisome thing about the latest results is that it shows the destruction of this ice shelf, a type of safety band that keeps the ice in place,” said Peter, a British Antarctic Survey oceanographer. “If this ice shelf is lost, the glacier will rush into the sea faster and contribute to sea-level rise.”
