Dissolved carbon dioxide forms carbonic acid, which dissociates and releases hydrogen ions, so the pH falls - by about 0.1 unit since pre-industrial times, which is a rise of roughly thirty per cent in hydrogen ion concentration. The same reaction consumes carbonate ion, making it harder for corals, molluscs and some plankton to build calcium carbonate structures.
