Greenland ice to melt completely with just 1.6° warming?

If the Greenland ice sheet were to melt completely, sea level could rise by 7 metres

A new study by the Potsdam Institute for Climate Impact Research and the Universidad Complutense de Madrid indicates that Greenland’s ice sheet could be much more vulnerable to climate change than previously thought. It estimates the trigger for a complete melting of the ice sheet at somewhere between 0.8 and 3.2°C of global warming, with the most likely figure at 1.6°C. above temperatures before industrialisation. A  O.8°C rise has already been registered. In the long term, a huge melting of land ice could result in major rises in sea level, which would threaten coastal and low-lying areas and the lives of millions of people.
