Short summary
A global model is constrained with empirical relationships to quantify how shifts in sinking-particle sizes modulate particulate organic carbon export production changes in a warming ocean. Including the effect of dynamic particle sizes on remineralization reduces the magnitude of predicted 100-year changes in export production by ~14 %. Projections of future export could thus be improved by considering dynamic phytoplankton and particle-size-dependent remineralization depths.
