  • The atmospheric circulation during the sea-ice maximum significantly impacts year-round Antarctic sea-ice area, with recent circulation changes having a notable, and previously overlooked, signature in recent ice losses, according to observational analysis.

  • The Southern Annular Mode (SAM) has shifted towards its positive phase owing to ozone depletion and increasing greenhouse gas concentrations. This Review discusses the dynamics, trends and projections of the SAM and how these will affect southern high-latitude climate, including Southern Ocean circulation, carbon cycling and the Antarctic cryosphere.

  • Abrupt changes are developing across Antarctica’s ice, ocean and biological systems; some of these changes are intensifying faster than equivalent Arctic changes, potentially irreversibly, and their interactions are expected to worsen other impacts across the Antarctic environment and global climate system.

  • Record-low sea ice coverage around Antarctica in 2022 and 2023 co-occurred with substantial subsurface ocean warming, which could be indicative of a change in the mechanisms that govern Antarctic sea ice, suggests an analysis of sea ice extent and ocean temperatures since 1979.
