对格陵兰冰盖顶部 GRIP 深孔的温度剖面进行建模，得出转换因子，从而可以将过时的稳定同位素剖面解释为跨越过去 113,000 年的气候温度记录。根据地表海拔变化进行校正后，格陵兰岛中部从晚冰期到北方温度的变化似乎为 22°C。格陵兰岛末次冰期结束时的变暖可能比南极洲更早开始。 DOI：10.1034/j.1600-0889.47.issue5.9.x
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 22 °C in central Greenland. The warming at the end of the last glaciation probably began earlier in Greenland, than in Antarctica. DOI: 10.1034/j.1600-0889.47.issue5.9.x
