Unexpected rise in carbon-fuelled ocean acidity threatens shellfish
The Guardian: The world's oceans are becoming acidic more quickly than climate change models predict, according to scientists who claim it will have a dramatic impact on marine ecosystems.
Water samples collected around an island in the eastern Pacific over the past eight years showed seawater had acidified more than 20 times faster than scientists expected. The effect could be devastating for shellfish and other crustaceans, because acidic waters dissolve calcium carbonate used by the organisms to make their protective shells.
