Short summary
We investigated how the Antarctic climate and ice sheets evolved during a period of warmer-than-present temperatures 4 million years ago, during a time when the carbon dioxide concentration in the atmosphere was very similar to today's level. Using computer models to first simulate the climate, and then how the ice sheets responded, we found that Antarctica most likely lost around 8.5  m sea-level equivalent ice volume as both East and West Antarctic ice sheets retreated.
