Response of the East Antarctic Ice Sheet to past and future climate change

The East Antarctic Ice Sheet contains the vast majority of Earths glacier ice (about 52 metres sea-level equivalent), but is often viewed as less vulnerable to global warming than the West Antarctic or Greenland ice sheets. However, some regions of the East Antarctic Ice Sheet have lost mass over re...
