From the original installment, the "Global" versus to Oceans series has been intend to show the impact of the Antarctic Continent and Circumpolar Current on Global climate and magnetic orientation. The potential instability of Antarctic Ice sheets to orbital and tidal forces can impact orbital and tidal forces. A complex set of tens of millennial scale climate related geophysical interactions.
The Scaled EPICA CO2 and the Baseline provided by Bintanja & van de Wal provide a "standard" for comparison to various regional reconstructions of past ocean climate.
Note: While I have reviewed the "Global" versus the Oceans posts, there are always chances to improve and correct. Any volunteer review comments are always welcome.
