Since the industrial revolution and the increase in the anthropogenic carbon dioxide emissions, surface ocean pH has on average dropped by 0.1 units, from 8.25 to 8.14, equal to a 30% increase in acidity. Rising global CO2 emissions could result in average ocean pH falling by 0.5 units by 2100. Acidification could then reach a level that has not been seen for millions of years, with potential impacts on sea life and all the goods and services ocean provides. (…)
