2010 Prediction by UN IPCC's Prof. Richard Alley, a Pennsylvania State University: "Sometime in the next decade we may pass that tipping point which would put us warmer than temperatures that Greenland can survive."
2020 Update: Paul Homewood's analysis: "Since then, however, Greenland’s temperatures have returned to normal, and are no higher than they were in the 1930s. Far from being the start of a new trend, 2010 was simply an outlier:
The Peterman Glacier is still more or less in the same position as it was ten years ago
Greenland’s major glaciers stopped retreating seven years ago
"A new reconstruction for SE Greenland (1796-2013) shows temperatures have risen and fallen without any hockey-stick-like trajectories for the last 200+ years. Temperatures were warmer than today in the 1920s and 1940s and even briefly during the 1800s."
