Short summary
The present study explains why Scandinavia was ice-covered 20 000 years ago, while Siberia was mostly ice free. The authors show that the ice-sheet extent in Eurasia was to a large extent controlled by atmospheric circulation changes due to the ice sheet in North America. As the North American ice sheet becomes larger, it induces a cooling in Europe and a warming in Siberia: this climatic pattern forces the Eurasian ice sheet to migrate westward until it is centered over Scandinavia.
