In this image proved by the European Space Agency, ESA, showing the glacier section that broke off the fjord called Nioghalvfjerdsfjorden, bottom, which is roughly 80 kilometers (50 miles) long and 20 kilometers (12 miles) wide, the National Geological Survey of Denmark and Greenland said Monday Sept. 14, 2020. The glacier is at the end of the Northeast Greenland Ice Stream, where it flows off land and into the ocean. Scientists with National Geological Survey see it as evidence of rapid climate change leading to the disintegration of the Arctic's largest remaining ice shelf. (European Space Agency via AP)
