Impacts of increasing CO2 upon the total Net Primary Production of marine systems and, thus, decreasing carbonate concentrations in the oceans and the atmosphere remain largely unknown. A global analysis reports that ~97% of reef areas exhibited warming trends, from 1985 to 2012. Coral bleaching incidents over the last two decades have been more frequent and more severe (Heron et al., 2016). Summarizing, ocean acidification has been affecting fundamental physiological and ecological processes of organisms (Hoegh-Guldberg & Bruno, 2010; Pörtner et al., 2014), leading to changes in the structure of marine ecosystems that underpin risks and vulnerabilities to food and income security (Hoegh-Guldberg et al., 2017). Thus, the impacts of ocean acidification have a direct consequence for societies, including changes in national economies (Busch et al., 2015; Robinson et al., 2010).
