Since 2017, the Antarctic sea ice extent has consistently been below the average value of the 1981-2010 reference period. In February 2023, this trend reached a new negative milestone.
According to Copernicus Climate Change Service (C3S) data, the Antarctic sea ice extent reached the lowest level ever recorded, standing at 34% below the reference average value. The deficit is evident in this image based on C3S ERA-5 data, which shows the widespread sea ice deficit in the entire Southern Ocean, with more pronounced anomalies in the Ross and Amundsen Seas.
Additional details are available in the latest C3S climate bulletin.
