It’s hard to overstate how crucial Greenland, and its kilometres-thick ice layer, is to climate change. If all that ice melted, the sea would rise by about seven metres – the height of a house.
But what happens if we fail to limit warming to 1.5°C (as looks increasingly likely)? And what happens if we do subsequently manage to rectify that “overshoot” and bring temperatures back down? A team of researchers writing in the journal Nature have now published a study exploring these questions.
