During glacial periods, the concentration of carbon dioxide in trapped air bubbles in glacial ice is lower when paralleled to the absorption throughout inter-glacial periods. A glacial period is otherwise glacial or glaciation is an interval of time which is thousands of years in an ice age that is manifest by colder temperatures and glacier progresses. Inter-glacial on the other hand, are stages of warmer climate among glacial periods.
