New 3D maps of the Greenland Ice Sheet show how huge cracks in the ice that accelerate melting expanded between 2016 and 2021.

The world's second biggest body of ice - the Greenland Ice Sheet - is cracking open quicker than scientists had previously thought. That's according to new research by a team of scientists, led by Dr Tom Chudley, from Durham University's Geography Department.

Observing Greenland from a helicopter, the main problem is one of comprehending scale. I have thought we were skimming low over the waves of a fjord, before noticing the tiny shadow of a seabird far below and realizing what I suspected were floating shards of ice were in fact icebergs the size of office blocks.

Greenland’s Ice Sheet is cracking open at the seams, literally falling apart at speeds indicative of the brutal and accelerating impact of global climate change. In just five years, 930 million cubic meters of crevasses opened up in the Greenland ice sheet.

The Greenland Ice Sheet is cracking open more rapidly as it responds to climate change. The warning comes in a new large-scale study of crevasses on the world's second largest body of ice.

Crevasses are widening faster as meltwater drives fissures deeper into the ice and lubricates the base of glaciers, increasing concerns about how quickly their melting will raise sea levels.
