Global warming (naturally by sunspots and solar flares) causes the sea surface temperatures to rise inducing more evaporation for more cloud cover which in turn cools the atmosphere back down, so the engine for the Ice Age was the ocean warmer, top to bottom, in the aftermath of Noah’s Flood, having been heated from below (“the fountains of the deep”) during the Flood, then it gradually cooled for almost a thousand years until it reached today’s temperatures by the time of the Exodus, the time of the “bronze age collapse” (when civilizations became deserts), when the Ice Age ended.
