The ocean becomes more acidic as it absorbs more carbon dioxide, with potential implications for marine life. (realclimate.org)
Scientists measure the carbon levels deposited by dying sea creatures, but the greenhouse effect also makes the oceans more acidic meaning that the calcium carbonate left by sea creatures is dissolved. (earthtimes.org)
Animals able to survive and reproduce in more acidic waters are likely to become smaller, potentially affecting the food chain that relies on them. (nhm.ac.uk)
