Antarctica's Ice Loss is Locked In, Even with 1.5°C Warming Limit

A new study published in *Nature Geoscience* indicates that Antarctica's ice loss this century is irreversible, even if global warming is limited to 1.5 degrees Celsius. This finding has significant implications for future sea-level rise, as the Antarctic ice sheet holds enough water to raise global sea level by approximately 58 meters (190 feet). The study examined hundreds of thousands of potential futures to assess the ice sheet's response to warming.
