Vulnerability of the West Antarctic Ice Sheet Determining the stability of the West Antarctic Ice Sheet in a warming climate is critical to forecasting future sea level rise. Keiji Horikawa et al. examined the isotopic signatures of detrital sediments in a drill core from the Amundsen Sea continental rise.
