The coloring around the coast of the Arctic island shows the speed of outlet glaciers flowing into the ocean. The 113-square-kilometre (43-square-mile) block broke off the Nioghalvfjerdsfjorden glacier in Northeast Greenland, which the scientists said had been expected given the rising average temperatures. World. Greenland's largest glaciers could lose more ice than previously predicted if emissions continue as 'business as usual' The arctic island is the largest land ice contributor to rising sea levels. The melting of Greenland's ice cap has gone so far that it is now irreversible, with snowfall no longer able to compensate for the loss of ice even if global warming were to end today, according to researchers.

Greenland’s glaciers contain around 8% of the world’s fresh water. Following the study’s publication, additional analyses show Jakobshavn grew thicker by 22 and 33 yards (20 to 30 meters) each year from 2016 to 2019.
