So what is currently happening with the climate is that increased CO2 and heat is being absorbed by the ocean. This is changing the ocean's PH balance, making it more acidic. THIS is what is causing the coral reef die-off. So unlikely that they will simply move. What is more terrifying is that as warming increases and acidity goes up, not only will the coral structures bleach and die out (50% complete), they will begin to actually dissolve, hampering any recovery. This would make the situation irreversible.
