“Uncontrolled melting”: they denounce the worrying situation in Antarctica

An “uncontrolled thaw” of the layers covering the Antarctic . This is what two scientists report in a study, published in the magazine Natural geosciences , which shows the alarming panorama that the continent is experiencing.

And as explained in Deutsche Welle , warm ocean water seeps between the ice and the land phenomenon that would not have been taken into account by other models, therefore Official reports would underestimate the total loss of ice .

This is what the situation looks like in Antarctica, according to the scientists’ report.

He global warming This leads to a considerable increase in the temperature of the oceans. AND This heat is responsible for the rapid melting of Antarctica’s ice caps and glaciers. and the new ice does not have time to form.

The consequences are that, As the ice melts, sea levels rise and endanger coastal communities.

This is why the recent report by the two scientists from Nature becomes more relevant: “The increase in ocean temperatures may lead to exceeding a tipping point, beyond which “Ocean water is penetrating unlimitedly under the ice cap, thanks to a process of uncontrolled melting.”

And, as the paper’s lead author, Alexandrey Bradley, explains, Warm seawater seeps into the “base zone” where land and ice sheets meet, over distances of 100 meters to tens of kilometers.

In the letter he also warned that Pine Island Glacier, the largest contributor to sea level rise in Antarctica, is at “high risk of melting.” due to the slope of the land on which it is located, as it allows the entry of much warmer sea water.

“In reality, (the study) does nothing other than stress the need for urgent climate action to prevent these tipping points from being exceeded. he concluded.
