Past Temperatures Directly from the Greenland Ice Sheet

TL;DR: A Monte Carlo inverse method has been used on the temperature profiles measured down through the Greenland Ice Core Project (GRIP) borehole, at the summit of the Greenland ice Sheet, and the Dye 3 borehole 865 kilometers farther south, resulting in a 50, 000-year-long temperature history at GRIP and a 7000-year history at Dye3.

Sticking deep ice core drills: Why, and how to recover
Niels S. Gundestrup,Sigfus J Johnsen,Steffen B. Hansen,Hitoshi Shoji,Pavel Talalay,Frank Wilhelms +5 more
TL;DR: The GISP/EPICA deep drill has suffered from two big setbacks: the drill is stuck both at NGRIP in Greenland and at Dome C in Antarctica as mentioned in this paper, and two reasons for the two events are believed to be different, but the chosen bore-hole liquid seems to be problematic.
