While the human impact on the reefs of the world can be slowed, the climate changes have happened before and will happen again. The reefs will adapt to different climate conditions. It has been observed that a few forms of (sp)Acropora and (sp)Montipora have already started to overcome warmer ocean temps. Bleaching is a natural way corals adapt to new conditions.
The direct human impact on the reefs is what is scary. Lime stone mines and pollution are the key factors. Thankfully most of the worlds reefs are far from people and large urban areas.
Coral grows at a extremly fast rate on a global time scale. And has showen a remarkable ability to overcome everything that Earth has throwen it's way over the last 60 million years. I think sometimes people just like to talk about the worst and not think about things on a global time scale..
