Description
Palaeotemperature estimates were obtained by Monte Carlo inversion techniques from a GRIP (72.58°N, 37.63°W) borehole temperature profile obtained near the summit of the Greenland Ice Cap. From the results plotted in the authors' Figure 6, it can be seen that temperatures during the Medieval Warm Period (~AD 800-1100) were about 1°C warmer than those of the Current Warm Period.
