Moreover, even if they can stop the heat, how are they planning to stop ocean acidification? Will they build a wall around the reef and manage pH within?

AFAIK, if the water acidifies even a bit more, no living organisms will be able to have any shells of any kind on them as the water becomes corrosive and simply dissolves the shells over time.

corals are sensitive to rapid and wide changes in water parameters whether it be temperature, pH, alkalinity. Due to the how large the volume of water that is in the ocean these parameters really don't fluctuate as much as you would think besides temperature. pH only dictates how fast coral can grow but corals are much more sensitive to changes in temperature and alkalinity.

Ah, what you want to say is you only care for the fast death of coral reefs and don't care for things that ensure its death but will take maybe a decade or two?

pH does not fluctuate much, true, but it drops steadily which is just as deadly to coral.

If it takes a few more decades, we could presumably find/implement better solutions.

Corals are more likely to survive a slow than a fast change as well. I don't think we know that much about how evolution bottlenecks work, but I'd think it's easier to adapt to a radically different environment in three generations than one.

Drop baking soda.

This isn’t just engineering, it’s mainly an emotional issue
