Ocean acidification, often referred to as “the other carbon dioxide problem,” is the progressive increase in ocean acidity that has taken place since the onset of the industrial revolution. Biological and ecological studies of ocean acidification impacts only began in the late 1990s, but the field has evolved rapidly, with exponential growth in the past decade. For example, 374 papers on this subject were published in 2013, compared with only 18 in 2004 (see http://tinyurl.com/oaicc-biblio).
