Antarctica sea ice reaches alarming low for third year in a row
The extent of ice floating around the continent has contracted to below 2m sq km for three years in a row, indicating an ‘abrupt critical transition’
For the third year in a row, sea ice coverage around Antarctica has dropped below 2m sq km – a threshold which before 2022 had not been breached since satellite measurements started in 1979.
The latest data from the US National Snow and Ice Data Center confirms the past three years have been the three lowest on record for the amount of sea ice floating around the continent.
Scientists said another exceptionally low year was further evidence of a “regime shift”, with new research indicating the continent’s sea ice has undergone an “abrupt critical transition”.
Antarctica’s sea ice reaches its lowest extent at the height of the continent’s summer in February each year.
