A mechanism for a post-flood rapid ice age of about 500 years is presented. It depends upon cooling over mid and high latitude continents by volcanic dust trapped in the atmosphere and by a widespread snow and ice cover. These strong cooling effects are balanced by a strong warming mechanism over mid and high latitude oceans. It also depends upon extra moisture provided by strong evaporation from a universally warm ocean. The resulting accumulation of ice at maximum glaciation is approximately 30% of that postulated by uniformitarian scientists. The present distribution of ice on Greenland and Antarctica is shown to be quite possible from a rapid ice age and the present climate in the time frame allowed by the Bible. As soon as the warm ocean cooled to near its present average, the present climate would begin to set in causing fairly rapid melting of all the Northern Hemisphere ice sheets except Greenland.
