24 Σεπ 2024 · Arctic sea ice reached its annual minimum extent of 4.28 million square kilometers on September 11, 2024, the seventh lowest in the nearly 46-year satellite record. The web page provides an overview of conditions, context, and trends in Arctic sea ice extent, as well as a table of the top 10 lowest minimums.
Sea ice extent, defined as the total area covered by ice of at least 15% concentration, is a common metric to assess seasonal and long-term changes in Arctic sea ice. Starting in 1979, there is now a 44-year record of ice extent derived from a consistent series of satellite-borne passive microwave sensors.
24 Σεπ 2024 · Arctic sea ice shrank to a minimal extent of 1.65 million square miles on Sept.11, 2024, the seventh lowest in the satellite record. Antarctic sea ice also declined to near record-low levels, reflecting global warming impacts on both polar regions.
