Sea ice levels in Antarctica are at an all-time low, the National Snow and Ice Data Center reports. Levels of sea ice in the region have reached record minimums this year, like in 2017 and 2022. Sea ice, the water that freezes on the surface of the sea in the Arctic and Antarctic hemispheres, has been decreasing in both regions. In Antarctica, sea ice levels reached record lows at least twice in 2023 after record minimums were detected in 2017 and 2022. Chart showing the levels of sea ice in Antarctica.
