Man-made carbon emissions have acidified the world's oceans far beyond their natural levels, new research suggests.In some regions, acidity levels rose faster in the last two centuries than it did in the previous 21,000 years, a study from the University of Hawaii has shown.Ocean acidity makes it harder for organisms such as molluscs and coral to construct the protective layers they need to survive.
