Imagine the amount of cloud cover during the Ice Age to have dumped all that snowfall, cloud cover which was not confined to just the high latitudes and elevations rather too over the low latitudes and elevations were rain fell not snow. That the Arctic coasts were green during the Ice Age gives the big hint for the source of that prodigious cloud formation, the ocean worldwide much warmer, having been heated from below during Noah’s Flood. The Ice Age ended when the average temperature of the ocean had cooled from about 80 deg. F. down to 50 deg. F. (today’s average temperature) by circa 1500. b. c.
