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

The Thwaites glacier in Antarctica is among the many greatest glaciers on the planet.

A glacier in Antarctica is melting at a quicker fee than beforehand anticipated, scientists introduced this month. In a brand new examine, printed in Nature Geoscience, they mentioned {that a} sudden melting occasion occurred over the course of six months within the final , which prompted the Thwaites Glacier retreat as a lot as 1.3 miles (2.1 kilometres) per 12 months. That’s twice the speed that scientists have noticed previously decade or so, mentioned the examine. Thwaites is known as the “doomsday glacier” due to the excessive threat of collapse and the risk to international sea stage.

According to People magazine, the Thwaites glacier is in regards to the dimension of Florida and accounts for round 5 per cent of Antarctica’s involvement in sea-level rise world wide.

“Thwaites is really holding on today by its fingernails, and we should expect to see big changes over small time scales in the future – even from one year to the next – once the glacier retreats beyond a shallow ridge in its bed,” mentioned Robert Larter, a marine geophysicist who co-authored the examine.

What Will Happen When Thwaites Disintegrates?

The scary new examine has alerted us in regards to the fast disintegration of one of many greatest glaciers on the planet. International Thwaites Glacier Collaboration, in an estimate released in 2020, had mentioned that if the “doomsday glacier” dissolves totally, it would result in 4 per cent of local weather change-caused sea-level rise.

They had additional mentioned {that a} sudden collapse would elevate sea ranges 25 inches extra.

Sea Level Rise Viewer, an internet utility developed by the National Oceanic and Atmospheric Administration (NOAA), permits customers to see what the collapse of the Thwaites Glacier would appear to be.

The utility exhibits the collapse of the glacier has the potential to devastate southern Louisiana and Mississippi. The results may even be felt in New York, however Los Angeles could be spared.
