Antarctica’s “Doomsday Glacier” On Edge Of Disaster, Says Study. Here’s What Will Happen If It Disintegrates


Research Says Antarctica's 'Doomsday Glacier'.  This is what will happen if it disbands

Thwaites Glacier in Antarctica is one of the largest glaciers in the world.

Scientists announced this month that a glacier in Antarctica is melting at a faster rate than previously expected. In a new study, published in Natural Geosciences, they say that a sudden melt event occurred in the last six months, causing the Thwaites Glacier to retreat 1.3 miles (2.1 km) per year. This is twice the rate scientists have observed over the past decade, the study says. Thwaites is known as the “doomsday glacier” because of its high risk of collapse and the threat to global sea levels.

Based on People magazineThwaites glacier is about the size of Florida and accounts for about 5% of Antarctica’s participation in worldwide sea level rise.

“Thwaites is really holding up today with its fingernails, and we should expect to see big changes on small time-scales in the future – even from year to year,” said Robert. – when the glacier retreats from a shallow ridge above its bed,” said Robert Larter, a marine geophysicist who co-authored the study.

What will happen when the Thwaites disband?

Scary new research has warned us about the rapid disintegration of one of the world’s largest glaciers. Thwaites Glacier International Cooperation, in a Estimated release in 2020has said that if the “doomsday glacier” were to melt completely, it would lead to 4% of sea level rise caused by climate change.

They added that a sudden collapse would raise sea levels by 25 inches.

Sea level rise viewera web application developed by the National Oceanic and Atmospheric Administration (NOAA) that allows users to see what the collapse of the Thwaites Glacier looks like.

The app shows the potentially devastating glacier collapse of southern Louisiana and Mississippi. The effects will also be felt in New York, but Los Angeles will be spared.
