Coral demise?

I recently read a very disturbing article regarding the increasing acidity of the world's oceans and the likely effect on coral. I know that a debate continues (not for me) as to wether there is or isn't global warming. What is undeniable is that we have, through industrialization, pumped billions of tons of carbon into the atmosphere which has been taken up by the oceans waters. I have pasted the link to The New Yorker Magazine article here:
