COPENHAGEN, Denmark — An enormous chunk of Greenland’s ice cap has broken off in the far northeastern Arctic, a development that scientists say is evidence of rapid climate change.
The glacier section that broke off is 42.3 square miles. It came off of the fjord called Nioghalvfjerdsfjorden, which is roughly 50 miles long and 12 miles wide, the National Geological Survey of Denmark and Greenland said Monday.
The glacier is at the end of the Northeast Greenland Ice Stream, where it flows off the land and into the ocean.
Annual end-of-melt-season changes for the Arctic’s largest ice shelf in Northeast Greenland are measured by optical satellite imagery, the survey known as GEUS said. It shows that the area’s ice losses for the past two years each exceeded 19 square miles.
“We should be very concerned about what appears to be progressive disintegration at the Arctic’s largest remaining ice shelf,” said GEUS professor Jason Box.
