Depends on the pH of the water. Disintegration would occur far more
readily in water that is acidic and would occur much more slowly in
alkaline water. Unless there is a tramatic alteration in the pH of
the oceans and that is unlikely as CO2 dissolved in water can form a
slightly alkaline buffer then I wouldn't think that CO2 released from
coral skeletons would be a big problem.

That is just part of the explanation for the very complex system of
gases, temperatures, currents and chemical composition of the oceans.
The oceans are a large part but still a portion of climate stability.
The jury is still out on what is going to happen 10, 50 or 500 years
from now.
