This is why a cessation of anthropogenic contributions to atmospheric CO2 would eventually tend to return atmospheric concentrations to the preindustrial level of about 280 ppm in the absence of other perturbations of the balance between the atmosphere and other parts of the system.

Obviously, we, the denizens of the world, will determine the future course of human emissions to the atmosphere as well as other perturbations to the earth. (realclimate.org)
The concept of OA by anthropogenic CO2 suffices to accommodate the changes observed in the open ocean, where other perturbations such as atmospheric deposition of reactive sulfur and nitrogen play a minor role and where, perhaps with the exception of the Arctic Ocean, watershed perturbations are minimal.
