Greenland's Melting Ice Shelves Fuel Rising Sea Levels

Greenland's ice shelves, which play a crucial role in holding back sea level rise, have lost 35% of their volume since 1978, equivalent to approximately 400 billion tons of floating ice. Only five large ice shelves remain, including Petermann, Ryder, and 79 North, which could contribute 3.6 feet of sea level rise if they were to melt entirely. The retreat of these ice shelves is a clear sign of the weakening ice shelf system in Greenland, with potential grave implications for future sea level rise.
