>Overall, the long-term trend in Antarctic sea ice is nearly flat. (in contrast, the glaciers and ice sheets over land in Antarctica are losing mass.) The satellite record spans more than four decades, and although the ice has shown increasing and decreasing trends over portions of that record, few of those trends have been statistically significant. Year-to-year variability has dominated, especially over the last decade. Since the year 2013, Antarctic sea ice has exhibited its highest and lowest extents in the entire record—the highest-ever winter maximum occurred in September 2014, and the lowest-ever summer minimum was in February 2022. But the overall trend, as of early 2022, is close to zero.
