  abstract = {{A}ccurately representing the ocean carbon cycle in {E}arth {S}ystem {M}odels ({ESM}s) is essential to understanding the oceanic {CO}2 sink evolution under {CO}2 emissions and global warming. {A} key uncertainty arises from the {ESM}'s inability to explicitly represent mesoscale eddies. {T}o address this limitation, we conduct eddy-resolving experiments of {CO}2 uptake under global warming in an idealized mid-latitude ocean model. {I}n comparison with similar experiments at coarser resolution, we show that the {CO}2 sink is 34% larger in the eddy-resolving experiments. 80% of the increase stems from a more efficient anthropogenic {CO}2 uptake due to a stronger {M}eridional {O}verturning circulation ({MOC}). {T}he remainder results from a weaker reduction in {CO}2 uptake associated to a weaker {MOC} decline under global warming. {A}lthough being only a fraction of the overall response to climate change, these results emphasize the importance of an accurate representation of small-scale ocean processes to better constrain the {CO}2 sink.},
