Abstract

The article focuses on the hidden geological features of Greenland, particularly beneath its extensive ice sheet, which could raise global sea levels by 7.5 meters if melted. It discusses the historical context of Greenland's ice cover, revealing that the landscape was largely ice-free tens of thousands of years ago and that the current ice sheet formed during various glaciation events. Scientists have utilized radar technology from NASA's Operation IceBridge to uncover a significant canyon beneath the ice, which influences how meltwater drains into the ocean. The article highlights the complexity of Greenland's topography, including its ancient bedrock and the rapid melting of glaciers, which is occurring at an accelerated rate compared to 25 years ago.
