Where might we find evidence of a Last Interglacial West Antarctic ice sheet collapse in Antarctic ice core records?
Abundant indirect evidence suggests that the West Antarctic Ice Sheet (WAIS) reduced in size during the Last Interglacial (LIG) compared to the Holocene. This study explores this possibility by comparing, for the first time, ice core stable isotope records for the LIG with output from a glacio-isost...
