there is room for debate about the overall impact of mankind's contribution to global warming and neither side will convince the true believers on the other side.  

having said that, there is absolutely no doubt about the toxic effects of carbon dumping into the atmosphere and the oceans.  

acidification of the oceans is quantifiable and cannot be denied.
  
it also cannot be denied that increased carbon levels can be directly related to human activity and that ocean acidification represents a deadly threat to all life on this planet.

instead of arguing the finer points of warming and climate change, the debate should center on the skyrocketing amounts of carbon in the oceans.

that is something everyone can agree on.  

methods for achieving lower carbon levels, whether or not one believes in global warming, should be the crux of the debate.
