The data here indicates that deep ocean mixing and the CPC are major factors controlling Southern Hemisphere CO2 Concentration. Since CO2 is a fairly well mixed gas, then the CPC and deep ocean mixing would play a major role in regulating global CO2.
Webster, a denizen on Dr. Judith Curry's Climate Etc. blog has meticulously calculated the CO2 uptake of the oceans and the rate of heat diffusion into the global oceans without considering the mixing that occurs in the southern oceans. That would make his work useless, but humorous :)
