Summary
[edit]
| Description |
The ice cover of the Last Glacial Maximum, about 20'000 years ago, is asymmetric with respect to the present position of the North Pole in the Arctic Sea. The North Pole was presumedly positioned in Greenland. A modeled path of a rapid polar shift is shown. It is a spiral, starting in Greenland and ending in the Arctic sea. A turn takes about 400 days. A relaxation time of 1000 days for global deformations of the Earth was assumed. |
