Greenland Glacier Melt

This Aug. 16, 2010, image provided by NASA Earth Observatory shows a piece of the Petermann Glacier that cracked in Greenland. A study in the Proceedings of the National Academy of Sciences on Monday, May 8, 2023, found that tides and climate change are rapidly melting ice in the grounding line zone of the Petermann Glacier. That’s the point where glaciers go from being on land to floating on water.
