Greenland is melting less quickly than 80 years ago: ‘55% of the retreating glaciers were retreating at a faster rate 80 years than in recent years’
'On the other hand, the average rate of retreat (in meters per year) is higher today than it used to be because there are some isolated very quickly retreating glaciers today. The evidence convincingly shows that the dynamics of the Greenland's ice is qualitatively similar to what it was 80 years ago when the carbon dioxide emissions per year were 4 times lower than today'
