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

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.

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.

The loss of ice on Greenland has been behind a sea level rise of around 14mm since 1992, scientists have said. If the entire Greenland Ice Sheet was to melt, sea levels could rise

Large-scale study finds crevasse sizes on Greenland ice sheet increasing in size and depth – and may cause more rapid loss of ice from region
