Increasing ocean stratification associated with global
warming has been posited to serve as a positive feedback on global warming,
reducing the oceanic uptake of anthropogenic carbon dioxide. We suggest that a
poleward shift of westerly winds combined with future increases in atmospheric
carbon dioxide may drive an increase in the CO2 uptake in the
Southern Ocean, representing a negative feedback on atmospheric anthropogenic
CO2.
