During the Ice Age, for all that snowfall (and more rainfall most everywhere else), the sky was filled with clouds much more-of-the-time, more clouds globally because the surface of the ocean was providing more vapor by evaporation, the ocean warmer, and obviously not by global warming, so having been heated from below. The roughly nine-hundred-years from Noah’s Flood to the time of the Exodus is the time it took for the world ocean to cool from an average of 80 deg. F., right after the Flood, down to the average 50 deg. F. which it has remained since circa 1400 b. c.
