The societal challenge of ocean acidification http://apocadocs.com/s.pl?1276176483
[S]ince the beginning of the industrial revolution, the oceans have taken up approximately 30 percent of the CO2 produced from fossil fuel burning, cement manufacture and land use changes.... While the invasion of CO2 into the ocean removes this greenhouse gas from the atmosphere and thereby dampens global warming, it forms carbonic acid in seawater and lowers ambient surface ocean pH... [It] will become more pronounced as humankind emits more CO2 into the atmosphere, with surface ocean pH expected to decline by a further 0.3 pH units by the end of the century, corresponding to an approximately 100 percent increase in ocean acidity.... Such a rapid change in ocean pH has very likely not happened since the time the dinosaurs went extinct 65 million years ago.
