How long an ice age?
Meteorologist Michael Oard22 has estimated that it would have taken only about 700 years to cool the polar oceans from a uniform temperature of 30C at the end of the Flood to the temperatures observed today (average 4C). This 700-year period represents the duration of the Ice Age. The ice would have started accumulating soon after the Flood. By about 500 years after the Flood, the average global ocean temperature would have cooled to about 10C, and the resulting reduced evaporation would have caused much less cloud cover. This, combined with the clearing of the volcanic dust from the atmosphere, would have allowed more radiation to penetrate to the earth’s surface, progressively melting the ice sheets. Thus the glacial maximum would have been about 500 years after the Flood. Interestingly, there seem to be certain references to this Ice Age in the ancient book of Job (37:9–10, 38:22–23, 29–30), who perhaps lived in its waning years. (Job lived in the land of Uz, Uz being a descendant o
