Possibly.... the fact that North America is moving SOUTH west tectonically, AWAY from the POLE....
Indeed, Greenland is today where North America was 30-50 million years ago, with the SAME RESULT...
Ice ages are CONTINENT SPECIFIC. They originate when land gets to within 600 miles of a POLE. There, the annual snowfall ceases to fully melt in the summer, and hence
STARTS TO STACK, and it is that stacking that is the start of an ice age which is continent specific because ice does not grow out over ocean, it BREAKS OFF.
Stack for 1 million years - Greenland
Stack for 40 million years - Antarctica
At its peak North American Ice Age, its true name before McBullshit, had 2.5 mile thick ice down to Chicago, over 5 million cubic miles of ice.
The argument between North American Ice Age (EMH) and McBullshit (Toddster) is here, have at it....
This is where the climate debate is now stuck. Every piece of land within 600 miles of a pole is in ice age, everything outside of that is not. Nobody has attempted to dispute that. It is the clear truth of Earth today. Milankovitch Cycles, which I call McBullshit Cycles, take a very...

ICE AGES end when the land moves to a distance of more than 600 miles from a POLE, explaining why North America just exited its ice age, except for Ellesmere Island, which is still inside 600 miles...
