temperatures, for example, ranging from 2 C warmer than prein-

dustrial. For vegetation changes, shown in Fig. 2 c, d for 410 ka BP, the results from
the two models once more agree well, showing a northward shift of the taiga-tundra
boundary in the high northern latitudes. Reconstructions from terrestrial records
(Kleinen et al. 2014 ) show a similar magnitude of climate change, but the coverage
by well-dated high-resolution records is very limited, preventing a model-data
comparison for more than a few points.
