Fig. 1

a Seasonal time series of sea ice extent (SIE) in the whole Antarctic from 1979 to December 2023 and the linear trend fit to the 10 years from June 2013 to May 2023 (blue line) is shown. Linear trends of seasonal mean fields in b–e satellite-derived sea ice concentration (SIC) and f–m ERA5 reanalyzed sea level pressure (SLP, interval 1 hPa/decade), 850 hPa wind (UV850), and surface air temperature (SAT) from June 2013 to May 2023. ** in (a) indicates the significant linear trend of SIE at the 95% confidence level. Dotted in (b–e, i–m) and shaded areas in (f–l) indicate the statistical significance of trends of SIC, SLP, and SAT at the 90% confidence level.
