  • Antarctic sea ice extent decreased abruptly in 2016 and has remained low since then, with similar drops in the 1970s but smaller magnitude, in which the higher sea ice loss occurred in the East Antarctic sector due to ocean atmospheric forcing, according to results from a multi-variate spatial reconstruction from 1958 to 2023.

  • Antarctic sea ice extent is thought to be stable or increasing, in contrast to Arctic declines. Estimates of seasonal Antarctic sea ice from reconstructions show that increases are confined to the satellite era, post-1979, with substantial decreases in the early and mid-twentieth century.

  • Surface air temperatures at the South Pole warmed at over three times the global rate in recent decades. Research shows this trend was driven remotely by the tropics and locally by a positive phase of the Southern Annular Mode, increasing the influx of warm moist air atop anthropogenic warming.

  • Recent anomalous variations in Antarctic sea ice extent are unlikely to have occurred during the early 20th century, according to reconstructions using a Bayesian statistical framework, which suggests a change in state to one of more persistent extremes.

  • Tropical teleconnections can influence polar climates through the generation of stationary Rossby waves. This Review outlines the dynamics and impacts of long-term tropical–polar connections on the Antarctic climate, which include warming trends and ice mass loss in West Antarctica.

  • Antarctic climate trends observed in the satellite record are compared with a two hundred year paleoclimate record. The satellite record is found to be too short to attribute changes to anthropogenic forcing, with natural variability overwhelming the forced signal.
