Editorial statement

This interesting study investigates the vulnerability of the Greenland ice sheet to climate warming. Specifically, the article addresses what it takes to make the Greenland ice sheet disappear—an event that would cause several metres of sea-level rise. The authors show that a tipping-point behaviour can be identified in their model, demonstrating that once a threshold has been crossed, Greenland becomes almost completely ice-free.
