A key measure of our understanding of polar glaciation is the ability to
model the initiation, maintenance, and elimination of glaciation over
Antarctica and high-latitude land masses in the Northern Hemisphere. Studies
that address questions of Cenozoic Antarctic glaciation, as well as studies
that address questions of Pleistocene glaciation in the Northern Hemisphere,
are described in some detail. The intention is to emphasize and discuss
issues that are important in modeling these types of glacial events as much
as to present specific results.
