It seems the Potsdam Institute for Climate Impact Research cannot get it's facts together. In a grossly self-contradictory (and real world contradicting) study release, the institute makes absurd claims about future sea level rise. Evidently, the real purpose of this "study" was to provide the usual trolls for mankind's climate warming hoax new fear-mongering powder for their steadily diminishing stores of ammunition.
In time for the London Conference, the Potsdam Institute for Climate Impact Research released a study stating that if temperatures increase as little as 1.6° C (2.9° F) above the Little Ice Age, Greenland will melt and sea levels will rise by about 7 meters (23 feet).
There may have been an error translation, because the last two IPCC assessment reports (AR3 & AR4) did not recognize a Little Ice Age!
A quick look at the GISP2 ice cores from Greenland shows that for much of the past 10,000 years Greenland has been warmer than 1.6° C above the Little Ice Age temperatures [oops!], yet the ice is still there [oops again!].
Even at 3.2° C (5.8° F) above the Little Ice Age the temperature does not exceed -28.5° C (-19.3° F). [A bit difficult to melt ice at those temperatures!]

[SEPP Comment: The study does not explain the enormous accumulation of snow and ice on the top of the Greenland ice cap.]
