Adding lime to the oceans may address both the CO2 and pH, perhaps.
Besides, a little lime to any drink is nice..

Burgy brings up the suggestions by some of ways to delay impact of global
warming by doing things to the atmosphere to reduce the amount of solar
radiation reaching the surface.

In evaluating such proposals, it should be remembered that such approaches
(or any approach that does not address atmospheric CO2) will completely fail
to address one major impact of anthropogenic CO2, which is the acidification
of the world's oceans. Even if the temperature impact of the CO2 were
compensated, we would still be altering the pH of the oceans, with the
resultant impact (already beginning to be seen) on coral, plankton, fish,
