The problem is the rate at which these changes are occurring. What historically took 10's of thousands of years, we are doing in 100 years. Coral, trees, ect can only migrate across the Earth from one place to another at a very limited speed.
.
Evolution to adapt to changing ocean PH can only happen even slower. Based on thousands of generations of genetic mutation of survival of the fittest.

We are bowling over the biosphere much faster than it can migrate or adapt.
