New studies released on Monday show that a large portion of the West Antarctic Ice Sheet may have begun a slow but "unstoppable" collapse, with the demise of these glaciers taking place sometime during the next few centuries to as many as 1,000 years from now.
The findings do not significantly alter short-term sea level rise projections, but they mean that we may need to prepare for larger amounts of long-term sea level rise than previously thought.
