NASA has found a new iceberg the size of London

Scientists from NASA Earth Observatory have shown the futurean iceberg that formed due to a multi-kilometer crack in the Brunt Ice Shelf. The ice block is striking primarily for its size: according to the researchers, its area is 1.7 thousand square kilometers. This is comparable to the area of ​​London or a small country in Africa (Mauritius). Details are reported on the website of the organization.

Now the first in the world works on the Brant glacierfully mobile Arctic station - Halley VI. The latter will have to change its location, because as soon as two cracks on the glacier connect, a huge iceberg will break away from it, which will become the largest in the history of observations of this object. The crack propagation velocity is about 4 kilometers per year.

The movement of the crack can be traced through photographs taken in 1989 and in January 2019.

The exploration of the Brant glacier began in 1915,research stations have been working on it for more than 60 years. Because of the cracks, Halley VI was already moved three years ago. It is possible that this time it will again be necessary to shift the Arctic station.

Antarctic ice sheet in 2017 lostover 250 billion tons of ice. In the next few decades, the melting of the ice of the Antarctic may add to the rise in sea level to a few meters. It may seem that there is still a lot of ice, but in fact losses are already catastrophic now. This is due to climate change, which leads to a steady reduction in the mass and area of ​​Arctic ice.
