    "abstract": "The striking asymmetry of the ice cover during the Last Global Maximum\nsuggests that the North Pole was in Greenland and then rapidly shifted to its\npresent position in the Arctic See. A scenario which causes such a rapid\ngeographic polar shift is physically possible. It involves an additional\nplanet, which disappeared by evaporation within the Holocene. This is only\npossible within such a short period, if the planet was in an extremely\neccentric orbit and hot. Then, since this produced an interplanetary gas cloud,\nthe polar shift had to be preceded by a cold period with large global\ntemperature variations during several million years.",
