Scientists expose vulnerabilities of critical Antarctic ice shelf
21 September, 2022 Press releases
Pine Island Ice Shelf in West Antarctica, which holds back enough ice to raise sea levels by 0.5 metres, could be more vulnerable to complete disintegration than previously thought. A new study led by British Antarctic Survey (BAS) scientists shows two processes, whose recent enhancement already threatens the stability of the shelf can interact to increase the likelihood of collapse.
This large ice shelf (the section of the glacier that floats on the sea) controls the flow of ice from Pine Island Glacier, roughly the size of England, into the Amundsen Sea. This is a crucial role as the glacier is one of the world’s largest and fastest changing and is responsible for approximately 25% of ice loss from Antarctica. This equivalent to the amount of water in 13,000 Olympic swimming pools. More ⬇⬇⬇
