Under increasing atmospheric CO2 concentrations the changing Earth's radiative balance will influence the atmospheric and oceanic circulation. One of the consequences will be a modification of the ability of the ocean to absorb and store CO2. To a first degree of approximation the ocean's carbon uptake can be separated between solubility-driven and biologically-driven pumps. The separate impact of the changing ocean circulation on these two pumps is still unclear though a partial compensation between opposite responses is expected. We design a suite of model experiments to quantify these responses analyzing a preindustrial steady state and an evolving state with atmospheric carbon concentrations rising according to historical (1880-2009) and projected IPCC scenarios. All experiments are carried out in CM2Mc, a coarse version of one of the climate models (the GFDL CM2) used in the IPCC Fourth Assessment report. The ocean biogeochemical component is solved by the Biology-Light-Iron-Nutrients-Gas (BLING) model which allow the separation between biological and solubility contributions to dissolved inorganic carbon.
