"In the simulations, atmospheric CO2 is assumed to increase at a rate of 1% per year to four times its pre-industrial value and then decreases to the pre-industrial level at a rate of 0.5%, 1%, 2% per year, respectively."

Results show that "the annual mean state of surface ocean #carbonate chemistry fields including [H+] conc., pH & aragonite saturation state respond quickly to removal of atmospheric CO2. Yet, the change of seasonal cycle in CaCO3 chemistry lags behind the decline in atm CO2."

"When CO2 returns to the pre-industrial level, over some parts of the ocean, relative to the pre-industrial state, the seasonal amplitude of carbonate chemistry fields is substantially larger."

"Simulation results also show that changes in deep ocean CaCO3 chemistry lag behind atm. CO2 change. When CO2 returns to its pre-industrial value, the whole-ocean acidity measured by [H+] is 15%-18% larger than the pre-industrial level, depending on the rate of CO2 decrease."

"This study ascertains that even if atm. CO2 can be lowered in the future as a result of net -ve CO2 emissions, the recovery of some aspects of #OceanAcidification would take decades to centuries, which would have crucial implications for the resilience of marine ecosystems."
