Ocean Acidification

Global climate change deniers wishing to argue their position often point out the oceans, enormous as they are, act as huge “carbon dioxide sinks.” It is true, of course, that the oceans absorb about 30% of the atmospheric CO2 we emit each year. But this has its own deleterious (some marine biologists say “catastrophic”) effects, in the form of ocean acidification. Linked above is a good article on the subject.
