Zusammenfassung |
We simulate the last glacial inception, 115 000 years ago, with a three
dimensional thermomechanical ice sheet model of the Northern Hemisphere,
forced by a comprehensive coupled climate model. High oceanic heat transport
into the Nordic Seas prevents large scale ice growth over Scandinavia.
Glacial inception in the region starts on the highest mountains in the south
when sea surface temperatures in the Nordic Seas are reduced by at least
3 °C. Ice growth in Northern Scandinavia requires a cooling by at
least 4 °C. This is in good agreement with marine proxy data from the
Nordic Seas and North Atlantic as well as available terrestrial data. This
study thus provides a physical understanding and revised timing of the first
glacier advance over Scandinavia. |
