Sea ice extent

Graph showing declining sea ice in Antarctica across 2021–2025 and an average from 1981–2010.

This graph shows sea ice extent data (area of ocean with at least 15% sea ice concentration) for 2021–2025 and an average for 1981–2010 in grey.

This graph is from the interactive graph, courtesy of the National Snow and Ice Data Center, University of Colorado, Boulder. The graph has multiple parameters that users can select or deselect to drill down into the data.
