  • During the early Holocene epoch—and since the 1940s—variations in Southern Hemisphere westerly winds controlled the upwelling of Circumpolar Deep Water and seemingly ice-sheet retreat in West Antarctica.

  • Lead (Pb) isotopes from a ferromanganese crust reveal that during lukewarm interglacials before the Mid-Brunhes Event, stronger deep Southern Ocean stratification limited CO2 release, helping keep atmospheric CO2 levels lower.

  • While a number of subglacial lakes have been discovered beneath the modern Antarctic ice sheet, little is known regarding their prevalence during past glaciations. Here, Kuhnet al. present sedimentological evidence for an active palaeo-subglacial lake in Pine Island Bay during the last glaciation.

  • The East Antarctic ice sheet is believed to be Earth's most stable ice sheet. Changes in geochemical composition of offshore sediments suggest that its margin repeatedly retreated by at least 350–550 kilometres inland between 5.3 and 3.3 million years ago.

  • Marine ice streams whose beds deepen inland are thought to be inherently unstable. Numerical modelling of the Maguerite Bay ice-stream retreat in West Antarctica since the Last Glacial Maximum suggests that an ice stream can stabilize on an inland-sloping bed owing to increased lateral drag where the ice stream narrows.

  • The Thwaites Glacier grounding zone has experienced sustained pulses of rapid retreat over the past two centuries, according to sea floor observations obtained by an autonomous underwater vehicle.

  • Oxygen depletion in the ocean interior may be closely linked to atmospheric CO2level, yet robust proxies are scarce. Here, using foraminiferal I/Ca as a proxy for oxygenation changes, the authors show that oxygen depletion in the upper waters of the high latitude Southern Ocean occurred during glacials.

  • The glaciated history of South Georgia is debated, with many suggesting a coastal limit to the island’s ice cap during the last glaciation. Here, the authors show extensive ice-cap cover of the continental block during this time and a readvance of glaciers to fjord mouths during the Antarctic Cold Reversal.

  • Multi-proxy core data and model simulations support the presence of temperate rainforests near the South Pole during mid-Cretaceous warmth, indicating very high CO2 levels and the absence of Antarctic ice.

  • The recent collapses of ice shelves in Antarctica due to warming make it essential to understand past ice shelf conditions and mechanisms. Here Smith and colleagues review the latest progress in deciphering the geological imprint of Antarctic ice shelves via sediments, landforms and proxy indicators.
