Melting Mysteries Unlocked at Greenland’s Grounding Zones
Petermann Glacier drains about 4 percent of the Greenland Ice Sheet as it moves inexorably toward the Arctic Ocean. A new observation and modeling study shows that the glacier is more vulnerable than previously thought to the intrusion of warm ocean water on its underside, leading to accelerated melting and boosting the potential severity of future sea level rise.
