Antarctic sea ice has likely shrunk to a record low, US scientists announced on Monday, raising concerns that the climate crisis is increasingly destabilising the frozen continent.

The 2023 minimum is the lowest in 45 years of satellite record-keeping, according to preliminary findings from the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder, published on Monday.

Antarctica reached its minimum extent for the year at 691,000 million square miles on 21 February, researchers said, beating the record low set in 2022 by 52,500 square miles.
