Your forgetting the time it took for these changes to occur. The changes in atmospheric CO2 levels and ocean PH levels did not fluctuate this fast during the "radical changes" your speaking of. They were much more gradual...tens of thousands of years, not hundreds. The changes didn't kill off the species your speaking of because they didn't happen fast.

Besides, I hope one day when I have kids, they can dive some of the spots around the world I have been lucky enough to visit and still see them in half decent condition. Diving in Australia was the most beautiful experience of my life and yet the local divers who had been in these spots for 30+ years would all tell you the reef was steadily heading downhill.

Im not sure why your trying to defend rapidly declining reefs as ok or normal???
