• Natural carbon dioxide (CO2) vents on the sea floor show how carbon emissions will affect marine life. Dissolved CO2 makes water more acidic. Around the vents, researchers saw a fall in species numbers and snails with their shells disintegrating.
• UK scientists suggest these impacts are likely to be seen across the world as CO2 levels rise in the atmosphere. The scientists observed the shells of marine snails (Osilinus) dissolving as the pH of the seawater fell below 7.6 around the vents.
