New research reveals that the dreaded ‘Doomsday Glacier’ in Antarctica isn’t so terrifying after all.
THE Doomsday Glacier in Antarctica, the Thwaites Glacier, is collapsing, threatening to raise global sea levels by three feet. New research, on the other hand, reveals that the ice sheet may be more stable than previously thought.
The Thwaites Glacier, which is located on the West Antarctic Ice Sheet, covers an incredible 74,000 square miles, nearly the same size as the state of Florida in the United States. The massive iceberg is well-known for its vulnerability to global warming and climate change. Thwaites, together with the Pine Island Glacier, Antarctica’s fastest melting glacier, is one of the world’s largest and most unstable glaciers.
The glacier has received the moniker “Doomsday Glacier” due to its perilous state.
Scientists are concerned that Thwaites will one day fall into the Amundsen Sea, dramatically rising sea levels.
However, according to recent research from the University of Michigan, the world’s largest ice sheets may be more stable than previously assumed.
The study, which was published in the journal Science, simulated the Doomsday Glacier collapsing, potentially providing insight into Antarctica’s uncertain future.
Thwaites has been shedding worrying amounts of ice into the Amundsen Sea, according to satellite data collected by NASA.
This is concerning because the glacier is losing more ice than precipitation can replenish further inland.
“What the satellites are showing us is a glacier falling apart at the seams,” Ted Scambos, a senior scientist at the University of Colorado, said in 2020.
“Every few years, a new sector appears to be releasing and speeding up.
“This glacier is being pulled into the ocean like taffy.”
According to new research, a glacier’s fragility may not always result in its rapid collapse.
Ice, according to Jeremy Bassis, an associate professor of climate and space sciences and engineering at the University of Michigan, behaves like pancake batter over lengthy periods of time.
“As a result, the ice spreads out and thins quicker than it can fall, stabilizing collapse,” he explained.
“However, if the ice cannot thin quickly enough, rapid glacial collapse is a possibility.”
The findings of the study have implications for the idea of ice cliff instability, which states that ice might suddenly disintegrate if the cliff reaches a particular height.
Icebergs breaking off from a glacier, known as iceberg calving, were also discovered by the researchers. “Brinkwire News in Condensed Form.”
