Study of Antarctic ice’s deep past shows it could be more vulnerable to warming

A new study led by Imperial College London scientists has found that the West Antarctic Ice Sheet (WAIS) was larger than previously thought during colder periods in the Miocene, contributing significantly to sea-level rise events millions of years ago. This insight will help researchers predict the future of the WAIS as the world warms.
