Sea acidification conditions growing to worst since age of dinosaurs, extinction

Scientists from Bristol University presenting at a three-day climate summit in Copenhagen have found the intensifying acidification of the world’s seas are creating conditions not seen since the age of the dinosaurs — and introducing huge new stresses on marine populations. Scientists liken the current acidification — which is being provoked by global carbon emissions — to a prehistoric release of greenhouse gases that led to acidification so severe it prompted widespread extinction of deep-water species. The report finds the current future rate of surface ocean acidification to be unprecedented for nearly 65 million years, with conditions even worse for the deep sea.
