Short summary
The net uptake coefficient of anthropogenic CO2 by the global ocean (net uptake flux divided by excess atmospheric CO2 stock above preindustrial levels) calculated with a simple, transparent, three-compartment concentration-driven model with two independent parameters is determined to be 0.010 ± 0.002 yr-1 (with a net uptake flux in the year 2022 of 2.84 ± 0.6 Pg yr-1). This result compares well with observations and with much more complex carbon cycle models.
