An '''Ice Age''' is a period of [[Earth]]'s history when [[ice]] sheets covered a much larger part of the [[planet]] than is currently the case.  The consensus of scientists is that several such periods have occurred over millions of years of geological time, although this view is disputed by a small group of scientists who believe in [[Young Earth Creationism]] (see also [[Creation Science]]).
