This phenomenon is not due to climate change, although the region is threatened by global warming, according to the British Antarctic Survey (BAS).
A huge iceberg, 15 times its size Parisbroke away from Antarctica on Sunday, British scientists said today.
This phenomenon is not due to climate change, although the region is threatened by global warming, according to the British Survey Antarctic (BAS).
The 1,550 square kilometer iceberg broke off on Sunday at around 21:00-22:00 (Greece time) when the tide widened a pre-existing crack in the ice, called Chasm-1, said BAS, an organization involved in polar research. areas.
Two years ago, an iceberg of about the same size had formed in the same area, the so-called Brad Ice Bank, where the British Halley V research station is located.
Glaciologists, who are in the area from November to March, have been observing the development of cracks in the ice for about 10 years. In 2016 the BAS decided to move Halley V by 20 kilometers, fearing that because the ice is melting it might find itself sailing on an iceberg.
“This detachment was expected and is a normal behavior of the Brand Ice Bank. It’s not linked to climate change,” explained ice scientist Dominic Hodgson.
Antarctica is suffering the effects of climate change and record temperatures were recorded there last year. In 2021, the complete melting of an iceberg, 4,000 kilometers from where it broke off in 2017, released more than 150 billion tons of fresh water, which worried scientists because they did not know what the effects would be on the region’s fragile ecosystem .
