Antarctic sea ice has historically shown a minimal long-term trend with high year-to-year variation. Scientists have largely attributed Antarctic sea ice behavior to natural variability. Beginning in 2016, however, Antarctic sea ice extent has mostly fallen below the 1981-2010 average, setting consecutive record low summer extents in early 2022 and 2023. Then in the austral winter of 2023, sea ice extent went off the rails—at one point falling more than 2 million square kilometers below the long
