Modelling the temperature profile along the GRIP deep bore at the summit of the Greenland ice sheet leads to conversion factors that allow interpretation of the dated stable isotope profile as a climatic temperature record spanning the last 113,000 years. When corrected for surface elevation changes, the late glacial to Boreal temperature shift appears to have been 22C in central Greenland. The warming at the end of the last glaciation probably began earlier in Greenland, than in Antarctica. STUDY NOTES: The profile shows the temperature of the GRIP borehole as measured in 1994.
