Ocean acidification: more than just corrals at risk

A new study on an array of marine animals shows that they all will suffer in different ways in the acidified oceans of coming decades.

That means rising carbon dioxide levels will trigger some profound reshuffling of life in the seas as some species are more hurt than others, according to a new report by Discovery magazine.

Because some of the carbon dioxide released into the atmosphere by the burning of fossil fuels is sucked up by the oceans, it causes sea water to gradually become more acidic.

There have been many reports about ocean acidification affecting marine organisms, but the severity of the threat to ocean ecosystems — and we humans who depend on them — is not at all well understood.

In a new paper in the journal Nature Climate Change, researchers document 167 studies that tested 153 species under a wide range of carbon dioxide concentrations.
