The internal chemistry of phytoplankton changes as oceans become more acidic

Our oceans are becoming more acidic, which could have major consequences for marine life. Of particular concern is what this could mean for phytoplankton, the microscopic photosynthetic organisms that form the basis of marine food webs and produce roughly half of the oxygen on Earth. Now, a study published in Nature Geoscience has found that the carbon dioxide we pump into the atmosphere is changing their internal chemistry.
