Models of glacial collapse in Antarctica improve predictions of sea-level rise

AI Summary

Improved models of Antarctic glacial collapse provide more reliable predictions of sea-level rise, a critical threat to the one-third of the global population living near coastlines. Forecasts estimate sea levels might rise between half a meter to 2 meters by the 21st century's end, potentially displacing hundreds of millions.

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 range from half a meter (1.6 feet) to 2 meters (6.6 feet) 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.
