An iceberg that broke off from the Doomsday Glacier began to move - for the first time in 20 years

Huge iceberg B-22A moved for the first time in 20 years and began to move away from Antarctica. Back in 2002, this block of ice broke away from Thwaites, which is called the "Doomsday Glacier" writes Live science.

In 2012, B-22A traffic brought a high ground to a halt on the seafloor. He was stuck 53 kilometers from the place of his appearance. That is, at that time it was moving at a speed of 2.6 kilometers per year, which is one of the slowest average movement rates of any iceberg in history.

But now the aging iceberg has been released and is catching up. This is indicated by NASA satellite photos from October 24, 2022. As of March 26, the B-22A has already moved about 175 kilometers to the northwest. In six months, he walked three times as far as in the previous 247 months.

At the same time, he retained most of his original ice, scientists say. Now its area is about 3,000 square kilometers.

Researchers are particularly concerned that the released B-22A could affect Thwaites' stability. Although

melting The Doomsday Glacier is slower than originally thought, but it still poses a threat. Latest Research showedthat in the future the rate of its disappearance could accelerate dramatically, harming the marine ecosystem and raising the level of the world's oceans.
