Chapter 6 Ocean Systems of IPCC Working Group II on ocean acidification

Extract from the Executive Summary of Chapter 6 Ocean Systems of IPCC Working Group II on ocean acidification Rising atmospheric CO2 over the last century and into the future not only causes ocean warming but also changes carbonate chemistry in a process termed ocean acidification (WGI AR5 Sections 3.8.2, 6.4.4). Impacts of ocean acidification range from changes in organismal physiology and behavior to population dynamics (medium to high confidence) and will affect marine ecosystems for centuries if emissions continue (high confidence). Laboratory and field experiments as well as field observations show a wide range of sensitivities and responses within and […]
