Short summary
We assess the long-term carbon cycle, climate and ocean acidification response of ocean alkalinity enhancement (OAE) using an emission-driven Earth system model across warming stabilization scenarios. OAE lowers atmospheric CO2 and produces a scenario-independent linear cooling. Gross carbon capture efficiency remains high, while net efficiencies decline over time due to carbon-cycle feedbacks. Ocean acidification mitigation by OAE is dominated by CO2 drawdown on long timescales.
