UK Parliamentary Office of Science and Technology on ocean acidification

The increasing amount of carbon dioxide (CO2) in the atmosphere is acidifying the oceans. The resulting changes to ecosystems and marine biodiversity may have negative impacts on fisheries and food security and reduce the coastal protection provided by coral reefs. This POSTnote outlines the science behind ocean acidification and summarises the threats to the marine environment. A global reduction of carbon emissions is the only certain way to minimise these risks.
