2. • 26 % increase in acidity due to CO2
emissions
• Many organisms show adverse effects
(corals, molluscs)
• Some thrive (e.g. seagrasses)
• Ecosystems will change in the future
• There will be socio-economic impacts
and need for adaptation
• Reducing CO2 emissions will reduce
impacts

Notas do Editor
To be launched at COP-19 in Warsaw in November.Unique features:- Great infographics- Confidence levels (like IPCC) on statementsNB. First bullet: Oceans [H+] has increased by 26 % since the start of the industrial revolutionEcosystems will change in the future, but how is difficult to predictThe magnitude of the socio-economic impacts are uncertain.Some people will need to adapt. E.g. Shellfish industry is already adapting on Pacific US coast.
