  • Beschreibung: <jats:title>Significance</jats:title> <jats:p> New information from the ANDRILL-2A drill core and a complementary ice sheet modeling study show that polar climate and Antarctic ice sheet (AIS) margins were highly dynamic during the early to mid-Miocene. Changes in extent of the AIS inferred by these studies suggest that high southern latitudes were sensitive to relatively small changes in atmospheric CO <jats:sub>2</jats:sub> (between 280 and 500 ppm). Importantly, reconstructions through intervals of peak warmth indicate that the AIS retreated beyond its terrestrial margin under atmospheric CO <jats:sub>2</jats:sub> conditions that were similar to those projected for the coming centuries. </jats:p>
