  1. Blunier et al. used methane records from the Greenland Ice Core Project (GRIP), Byrd, and Vostok to compare the timing of millennial-scale events between 10 and 45 thousand years ago (ka).They showed that warming in Antarctica preceded, by several millennia, the onset of warming in Greenland for Dansgaard-Oeschger (D-O) events 8 and 12—interstadial events that occurred at 38 and 45 ka (GISP2 ...

    Jan 10, 2025With the latest Antarctic ice core, scientists hope to learn how levels of greenhouse gases have changed over millennia. Scientists say that understanding Earth's climate history can help them ...

    A precise relative chronology for Greenland and West Antarctic paleotemperature is extended to 90,000 years ago, based on correlation of atmospheric methane records from the Greenland Ice Sheet Project 2 and Byrd ice cores. Over this period, the onset of seven major millennial-scale warmings in Antarctica preceded the onset of Greenland ...
  5. They can thus generate changes in the density of ocean surface waters and therefore in ocean thermohaline circulation; such processes involve deep ocean heat storage with constants of millennia. Notably, the obliquity components of temperature records from the tropical Pacific and from Antarctica are in phase within age scale uncertainties ...

    Oct 1, 2023Furthermore, the temperature changes over West Antarctica during the past two millennia are well correlated with the global mean surface temperature that has been shown to be strongly influenced by volcanic forcing (PAGES 2k Consortium, 2019; Schurer et al., 2014). The global-scale radiative forcing change appears thus to be responsible also ...
  8. The Antarctic Peninsula has seen a widespread retreat of marine glacier fronts and disintegration of floating ice shelves, whilst in the Amundsen coast region the extensive thinning of fast flowing glaciers has made this region one of the largest Antarctic contributors to sea-level rise.

    Antarctic heatwave. Between 1992 and 2017, global warming caused the loss of almost 2700 gigatonnes (2700 billion tonnes) of ice from the Antarctic ice sheet - including through the collapse of large ice shelves - contributing about 8 mm to mean sea level rise. ... where plants and animals have adapted over millennia to a specific narrow ...
