"Ice Age" Visualization

This app helps to visualize how the Pliestocene 'Ice Age' may have actually been a period of altered polar axis (ie. the north pole was over greenland instead of its present location).

sea ice extent in arctic & antarctic

Evidence for a TPW event is evident by investiagating the positioning of the ice cap and lack of continental glaciation in Siberia & Alaska. Note how the extent of the ice during 'Ice Age' was actually no bigger than the current arctic or Antarctic circles. (With the exception of 'Alpine Glaciers' such as the Canadian Rockies, Alps, Russian Mountains, etc. )

Ice polygons are taken from the current scientific consensus on continental ice age icecap extents.

Toggle on the following 'Antarctic overlay layer' to see the current extent or size of Antarctica with its associated winter sea ice superimposed upon the extent of the ancient northern hemesphere ice cap. You'll see how the pleistocene ice cap was essentially what would be expected of a different polar location.

A true polar wandering (TPW) event obviously changed the location of the pole around 9k BP. And continuing axis instability caused the 'Younger Dryas' event. Predomante scientific thought typically attempts to explain the lack of Ice Age Siberia/Alaska glaciation with 'Arctic desert' reasoning (it was too dry to snow there during the ice age). See my article for data on why these explanation don't add up. I talk more about this theory and other posibilities in my article on this topic found at this link.
