This view is though inconsistent, and not completely in line with what we see happening today at Antarctica.The centrifugal forces caused by the ice sheet on Antarctica today is about 2 times larger than the forces during the last ice age. So, what could power crustal shifts is unsure, but it could be driven by a combination of inner and outer events. Earth Crust Shifts be part of the vocabulary of any sane geologist to explain events that otherwise become unexplainable.The mountain peaks would start to accumulate an ice sheet after Greenland shifted 18° further up North to its current location, according to this new theory. This theory seems to be rather adhoc because it doesn’t cover the complete subject of ice sheet formation around the Arctic.
Thirdly, a shift of the Earth axis caused Greenland to move even further northward.
Even the mountains on Svalbard aren’t covered in thick ice sheets.
Scientists will probably think of very difficult explanations for this, but they then tend to forget about Occam’s Razor.
There’s no model possible that covers The reason for that [origin of ice sheet] is the interaction of three tectonic processes.
For one thing, Greenland had to be lifted up, such that the mountain peaks reached into sufficiently cold altitudes of the atmosphere.
