Geologists think (at least this is what my geologist flatmate tells me) that we're still in an Ice Age because we still have ice on the poles. The "natural" state of the Earth according to geologists is one where there isn't any ice sheets.
We're on our way out of one, very near the end in terms of ice age lifespans, but not out completely.
