A white, endless expanse of ice where it is freezing cold is how most people imagine the Greenland Ice Sheet. But it is not like that everywhere. This year, temperatures were well above average even in the middle of Greenland through December. Image: Dr Michael Wenger...
Wide, white and frozen. This is the surface of an ice shelf and the ice sheet behind it in Antarctica. But thanks to ice-penetrating radar and satellites, researchers are discovering that a whole other world lies hidden beneath the ice. Image: Dr Michael Wenger From...
The idea sounds simple: A curtain should prevent too much warm water from reaching the ice edge along the bottom and melting the ice from below. At the same time, however, the curtain should be flexible enough to allow icebergs from the glacier to drift out. Image:...
According to recent studies, the Antarctic ice sheet moves toward the ocean at different velocities depending on the season, as do Arctic and alpine land ice masses. Image: Copernicus/ESA Sentinel-1 satellite via University of Cambridge The Antarctic Ice Sheet, like...
