The simulated July temperature evolution for Greenland (Fig.  7 a, b) shows a response that is intermediate between North America and northern Europe.

The July temperature decreases by about 3°C over 9 kyr, but this is probably an overestimation (by about 0.5°C), as the effect of the summer insolation surplus was tempered by the residual Laurentide Ice Sheet in the early Holocene (compare ICE with MAIN in Fig.  7 b).

Our model results (Fig.  7 ) show a very similar amount of cooling (3°C) during summer as in NorthGRIP.

However, the clear climatic optimum is lacking in the main simulation, which may be caused by the lack of a residual Laurentide Ice Sheet in this experiment, as our ICE simulation produced a flatter summer temperature evolution over Greenland between 9 and 6 kyr BP (Fig.  7 b).
