Models of Glacial Collapse in Antarctica Improve Predictions of Sea-Level Rise

With approximately one third of the world’s population living within a day’s walk of a coastline, sea-level rise poses a serious global threat. Every centimeter of sea-level rise could displace 1.5 million people, and current estimates of rise range from half a meter to 2 meters by the end of the 21st century—which means that potentially hundreds of millions of people could be affected. A more reliable prediction of sea-level rise is crucial to prepare coastal infrastructure and communities around the world for these changes.
