An update on WACSWAIN: WArm Climate Stability of the West Antarctic during the last INterglacial

This joint project between the Department of Earth Sciences and British Antarctic Survey (BAS) aims to constrain estimates of if, how and when the West Antarctic Ice Sheet (WAIS) retreated during the Last Interglacial (LIG), 130 to 115 thousand years ago.

Evidence suggests that sea level during the LIG peaked at between 6 and 9 metres higher than present, a range which necessitates at least some contribution from Antarctic Ice Sheet retreat, the WAIS being the most likely candidate. Antarctic temperatures during this time period were in line with projections for the year 2100. These figures warn of the potential for significant future sea level rise resulting from anthropogenic climate change.
