Early experiments with Greenland ice sheet flour show it can capture significant amounts of CO2 and provide a wider range of nutrients than commercial organic fertilizers, leading to improved crop growth. In the long term, ice sheet flour could play a major role in halting climate change. The researcher behind the studies calls it a “promising, scalable solution.” Lots of gray mud. The Greenland Ice Sheet is slowly grinding the land it rests on into a very fine powder called glacial till. It lies like gray mud in the otherwise lush green or snow-white Greenland landscape and at first glance does not look like anything special. However, two new studies show that glacial stone flour is something very special.
