Have our oceans become more acidic because of CO2 emissions?

    The world’s oceans absorb about a quarter of the carbon dioxide emissions created by human activities each year.  This is partly good, because it reduces the amount of carbon dioxide contributing to global warming.  However, it is also a bad thing because carbon dioxide that dissolves in water leads to the creation of carbonic acid.  This increases the acidity of the oceans, harming the hard body structures of many marine invertebrates and potentially disrupting entire ocean food chains.  Studies have already suggested that some marine organisms are feeling the effects of ocean acidification.  However, the problem is certain to get much worse if we do not reduce carbon dioxide emissions dramatically.
