Iceberg 15 times bigger than Paris breaks off from Antarctica

my 500 square kilometer iceberg, equal to 15 times the area of ​​Parisbroke over Antarctica on Sunday, a group of British scientists reported on Monday.

Although the sector is at risk from Global warming, The British Antarctic Survey (BAS), an organization that researches the polar regions, said that the phenomenon is not due to climate change.

A 1,550 km2 section of ice broke away from the ice between 7:00 pm and 8:00 pm GMT on Sunday, after a strong tide widened an already existing crack in the ice shelf, the BAS elaborated.

Another iceberg of similar size had broken off two years earlier in the same area, called the Brunt Ice Shelf, on which the British Halley VI research base is located.

for a decade large cracks have grown On ice shelves, glaciologists make observations.

In 2016, BAS decided to move the Halley VI base to another location about 20 kilometers away, fearing that it would be swept away on an iceberg.

This detachment was expected and is part of the natural behavior of the Brunt Ice Shelf. It is not linked to climate change,” glaciologist Dominic Hodgson was quoted in a statement.

The continent suffers, however, consequences of global warming. Last year a record temperature was recorded in the region.

The amount of ice in that part is set in February 2022 to the minimum recorded in 44 years of satellite observations, indicated a recent annual report of the European Program on Climate Change Copernicus.

In 2021, the melting of an iceberg 4,000 km north of where it broke off in 2017 released more than 150 billion tonnes of nutrient-rich fresh water, prompting scientists to worry about its impact on a fragile ecosystem .
