Researchers said the development mirrored that of a neighboring glacier, the Zachariae, which collapsed into the ocean in 2015, leading to an increase in calving as it was heated from both the ocean and air. The 113 sq km block broke off the Nioghalvfjerdsfjorden glacier in Northeast Greenland, which the scientists said had been expected given rising temperatures. While it is normal for pieces of ice to break off from a glacier - a process called calving - they are generally not this large.

When the edge of an ice sheet breaks off and falls into the sea (calves), the remaining section of the ice sheet moves backward and down and can suffer a glacial earthquake. “If we see more warm summers like we observed the last two years, it will be contributing more to the accelerating global sea level rise,” Box said.
