What they do, is describe earth's climates going back 150 million years, how the continent of Pangaea and Gowanda land broke apart, how Antarctica drifted south, until it landed at the present location, with the circumpolar currents blocking warmer tropical currents from warming the area. This slowly built up an ice sheet that has been in place for millions of years.
