Excess carbon dioxide isn’t just building up in the atmosphere – the oceans are holding onto more of the stuff too, fizzing them up like soda. As the seas get warmer and more acidic, all kinds of havoc is wrought, and now a new study has identified yet another symptom. Researchers at Princeton and McGill Universities have found that the seafloor is beginning to dissolve as a result of human activity.

According to the Smithsonian’s Ocean Portal organization, about 525 billion tons of CO2 has been absorbed by the world’s oceans since the beginning of the industrial era, making seawater up to 30 percent more acidic than it was 200 years ago. That makes it the fastest known change in ocean chemistry in 50 million years or so, and the effects have already been devastating.

Ocean acidification is contributing to coral bleaching, upsetting predator/prey relationships, messing with the
