Of course the engine for the Ice Age was the ocean warmer for the greater evaporation for the greater cloud cover, and that greater cloud cover caused a relative uniformity of atmospheric temperatures, less temperature range, so although the precipitation rates (snow or rain) coming from clouds off the ocean were severe, they were not violent storms fed by great atmospheric temperature variations, also the uniformly warm ocean immediately following Noah’s Flood caused a certain quiescence although with the great evaporation off it.
