Short summary
An Earth system model was set up and applied to evaluate the effects of sea-level change, ocean dynamics, and nutrient utilization on seawater composition and atmospheric pCO2 over the last glacial cycle. The model results strongly suggest that global sea-level change contributed significantly to the slow glacial decline in atmospheric pCO2 and the gradual pCO2 increase over the Holocene whereas the rapid deglacial pCO2 rise was induced by fast changes in ocean dynamics and nutrient utilization.
