According to atheistic [[geology]], there have been many Ice Ages, the oldest hypothesized one being 2.3 [[billion]] years ago, and the most recent finishing around 11,500 years ago.<ref name="WBE" /><ref name="CAB">Batten, 2007</ref>

* The study of the ice ages is remarkably interdisciplinary. To be an expert in this field, a scientist must have a comprehensive knowledge of [[geology]], [[physics]], [[glaciology]], [[oceanography]], [[atmospheric science]], [[celestial mechanics]], [[solar system]] [[astrophysics]], [[cosmic rays]], [[solar physics]], [[interplanetary dust]], [[climate modeling]], [[spectral analysis]], and [[statistics]]. As a consequence, there are no real experts.<ref> [http://muller.lbl.gov/pages/IceAgeBook/preface.html Ice Ages and Astronomical Causes]</ref>

==Cooling and warming==

If the Earth cools down, [[evaporation]] and therefore [[precipitation]] are reduced, so little [[snow]] will fall onto land to form ice sheets.  If the Earth heats up, evaporation and precipitation are increased, but the precipitation falls as rain rather than snow, or melts rather than forming ice sheets.<ref name="CAB" />

The theory was first proposed by [[Louis Agassiz]] in 1837 to try to explain geologic features which until then had been explained by the [[great flood]].<ref>[http://earthguide.ucsd.edu/virtualmuseum/climatechange2/02_1.shtml Discovery of the Great Ice Age]</ref><ref>Aber, James S., [http://academic.emporia.edu/aberjame/histgeol/agassiz/agassiz.htm Jean Louis Rodolphe Agassiz]</ref>
