There have been over 30 glacial cycles over the last 3 million years so that land must be moving back and forth like...Where is the ice on Earth?
97.3% on the three land masses within 600 miles of a pole.
And yeah, there is no "ice cap" if there is no land, just sea ice, which on a pole with no land, would fully melt during summer.
There are no "glacials" and the glacials bullshit is completely refuted by
1. ice cores
2. the fact that Greenland froze while North America thawed
but it is your TAXPAYER FUNDED JOB to keep pushing "glacials" no matter how refuted they are...
