One question about the Ice Age is how many were there? Were there many over millions of years or just one, a few thousand years ago? The evidence clamed for more than one ice age is unsorted material known as till or tillite. Tillites have been found in low rock but contrary to the multiple ice age claim, they are small and thick making them more consistent with a marine origin. Also they are associated with limestone and dolomites that only form in warm water and therefore they are inconstant with glacial formation. Further more the largest boulders are smaller than those associated with glaciers. It is also known that under water mass flows produce tillite like deposits, so these would have occurred during the Flood. Hence the data is really consistent with only one short ice age.
Some people erroneously think that the ice age covered the entire Earth in Ice. In reality it covered no more than 1/3 of Earths land surface, but it did affect the entire Earth. First of all the continental shelves were above water because the ice lowered sea level. It would have produced higher rain fall in the lower latitudes so that present day deserts lake the Sahara, Gobi and Arabia would have had ample rain fall. Archeological excavations show evidence in these now desolate regions of lush vegetation, human occupation and complex irrigation.
The biggest question about the ice age is what caused it. The standard model has the entire earth cooling. The problem is that continents and oceans cooling will not produce an ice age. Cool oceans produce little evaporation, so they can not produce the snow needed for an ice age. The result is that this model does not work.
What is really required for an ice age is warm oceans to produces evaporation and cold continents. The resulting massive snow falls and insufficient summer melting allows snow and ice to acclimate. This would have been a natural result of a global Flood. The oceans would be warm from geologic activity but the continents would be cool as a result of dust from volcanic activity and clouds from evaporation.
Based on the Bible, the Flood occurred about 24,000 BC. It would have had
an effect on the climate of the ancient world, such that ancient civilization
now found in deserts would have had ample rain fall. This explains several
anomalies including the erosion on the Great Sphinx
of Egypt.
