Man-made carbon dioxide making oceans more acidic, study finds

Oceans worldwide are turning increasingly acidic as they absorb more carbon from the atmosphere, which could have negative effects on many forms of marine life at the base of the oceanic food chain, including plankton, coral and large mollusks such as oysters, a National Research Council study has found.

Oceans are an important part of the planet’s carbon cycle, and hold the largest active pool of carbon near the surface of the Earth. They absorb about a third of man-made carbon dioxide from the atmosphere, eventually converting it into carbonic acid and carbonic ions.
