Ice sheet and sea-level reconstructions from the past ?warmer-than-present?climates of the last 34 million years provide powerful insights into the longtermresponse of the polar ice sheets to climate changes projected for the 21st century and onward. Proximal geological evidence shows the onset of large-scale Antarctic glaciations occurred around the Eocene/Oligocene Transition at approximately 34 Ma. Since then, the AntarcticIce Sheet (AIS) evolution and variability, recorded in the direct geologicalarchives, have been widely compared with the benthic oxygen isotope proxyrecords of deep-water temperature and global ice volume from far-field deepocean locations.
