Although no one single source of evidence or locality yields the complete story of climate change and the onset of glaciation in Antarctica, piecing together information from a range of sources, as presented above, does provide a picture of how climate cooled and glaciation became established on the continent. A summary is presented below (for references, see text above). Paradoxically, the present ice sheet hides its own history, certainly at the highest latitudes in the middle of the continent, so most of what is known about past environments is from the lower latitude marginal sites.
