  1. While the Milankovich Cycles are important the critical thing to get Ice Ages going is Plate Tectonics. The Glacial Age in the Southern Hemisphere know cked off with South America and Antarctica seperating and the Circumpolar Current getting established 30 plus million years ago. The Northern Hemisphere's Glacial Age was enabled by the formation of the Ismuths of Panama. This blocked the exchange of warm water between the Pacific and Atlantic.
