Does the Atmosphere make any difference in the temperature, ice build up and climate of our planet?
You were just given the truth of the past million years, that Greenland froze WHILE North America thawed.
Which did the atmosphere do, the freezing, the thawing, or both???
A neither, since it was constant for both.
Greenland moved 20+ miles NW. As it moved, and it had been moving that way for more than 100 million years, its winters got longer and colder, its summers got shorter, and finally it reached a point where the annual snowfall ceased to fully melt during summer, and it started to STACK, and THAT is the start of an ICE AGE, which is CONTINENT SPECIFIC and not planetary.
Antarctica has 70 million year old dinosaur fossils on it. That is because it was not on the South Pole 70 million years ago - it moved there.
