abstract atmospheric carbon dioxide co 2 emissions human industrial activities causing progressive alteration seawater chemistry termed ocean acidification decreased seawater ph carbonate ion concentration markedly since industrial revolution many marine organisms like molluscs corals build hard shells skeletons using carbonate ions exhibit negative overall responses ocean acidification adds chronic acute environmental pressures promotes shifts away calcifierrich communities study examine possible implications ocean acidification mollusc harvests worldwide examining present production consumption export relating data present future surface ocean chemistry forecast coupled climateocean model community climate system 31 ccsm3 identify transition decade future ocean chemistry distinctly differ today 2010 mollusc harvest levels similar present cannot guaranteed present ocean chemistry significant determinant todays mollusc production assess nations vulnerability ocean acidificationdriven decreases mollusc harvests comparing nutritional economic dependences mollusc harvests overall societal adaptability amount time transition decade projected transition decades individual countries occur 1050 years 2010 countries low adaptability high nutritional economic dependence molluscs rapidly approaching transition decades rapidly growing populations therefore vulnerable ocean acidificationdriven mollusc harvest decreases transition decades suggest soon nations implement strategies increased aquaculture resilient species help maintain current per capita mollusc harvests
