Throughout much of the earth's history, the global climate was probably between eight and ten degrees centigrade warmer than it is today. This is true whether the geologic ages were long or short. From a creationist perspective, the ice ages occurred following the Flood, but may not have been necessarily associated with extremely cold average global temperatures. Oard2 has presented a model which shows that the ice sheets may have been a result of warm oceans and cold continents, following the Flood.
