Abstract
Ocean carbon storage responds to changes in atmospheric CO2, reflected in particular in the uptake of anthropogenic carbon under contemporary "net-positive" CO2 emissions. Under future net-negative emissions scenarios, however, the ocean is expected to release part of the previously absorbed anthropogenic carbon back to the atmosphere. In addition to this direct atmospheric CO2 effect, anthropogenic climate change modulates the uptake of anthropogenic carbon as well as impacts the natural carbon cycle, for instance an increase in sea surface temperature decreases solubility of CO2 in the ocean, and changes ocean stratification and hence ocean circulation.
