Greenland’s ice sheet has melted to ‘point of no return’

The ice sheet on Greenland, the largest island in the world, has melted to a ‘point of no return’ according to a recent study and it cannot be stopped from disintegrating even if steps to slow global warming are successful. 

  • The ice sheet disintegration has been so massive that it has caused a change in the gravitational field over Greenland. 
  • The ice sheet had retreated in rapid bursts due to which there could be an unpredictable rise in sea levels and humanity would not be prepared to tackle the effects, the study said. 
  • The study’s authors used many decades of satellite data to measure changes to Greenland’s ice cap. They found that it had melted so rapidly after 2000 that fresh snowfall had not been able to keep pace and replenish what was lost.
