Daily ice extent around Antarctic in 2023 to date (dark red) compared to all years from 1979–2012 (light gray), years from 2013–2015 (blue), and years from 2016–2022 (light red). The annual winter maximum ice extent around Antarctica has been highly variable in the past decade, with some years above average and others below average. The 2023 record low, however, is far outside the range of previous natural variability. Animation by National Snow and Ice Data Center.
