There’s a book called ‘The Sixth Extinction’ By Pulitzer Prize winner Elizabeth Kolbert which talks about this. The sixth chapter is about the rise in ocean acidity.

She also details a critical acidity point (I forget the PH level but I think with current rise in acidity it is modeled to reach that point in 2100) where calcifiers cannot survive due to the acidity essentially breaking down their shells. Think oysters, barnacles, coral. Major parts of the ocean’s ecosystem that could have a ‘cataclysmic’ effect if wiped out.
