Iceberg the size of London and 15 times bigger than Paris breaks off in Antarctica

One big Iceberg Nearly the size of London and 15 times the area of ​​Paris, the Brunt Ice Shelf in Antarctica has broken through, a group of scientists British Antarctic Survey (BAS), an organization that investigates the polar regions, and which assured that it was not the reason Climate change.

According to experts, the Iceberg It covers an area of ​​1,500 square kilometers and broke away from the ice between 01:00 and 02:00 on Sunday, 22 January, after a strong tide widened a crack that already existed in the ice shelf. Was. Therefore, despite the fact that the region is at risk of global warming, the calving was not caused by climate change.

“This calving 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, however, suffers the consequences of Global warming: Just last year a record temperature was recorded in the area.

The amount of ice in that portion reached in February 2022 is the minimum recorded in 44 years of satellite observations, indicated a recent European program annual report. Climate change Copernicus.

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

Before that, the other had already separated Iceberg two years ago in the same area of ​​similar size, called the Brunt Ice Shelf and on which the British Halley VI research base is located.

According to experts, over the decade large cracks have grown in the ice shelves, which is why in 2016, BAS decided to relocate the Halley VI base to another site located about 20 kilometers away, fearing that it would risk Will be in drift on one Iceberg,
