«The authors write that «the El Niño - Southern Oscillation (ENSO) is a naturally occurring fluctuation,» whereby «on a timescale of two to seven years, the eastern equatorial Pacific climate varies between anomalously cold (La Niña) and warm (El Niño) conditions,» and that «these swings in temperature are accompanied by changes in the structure of the subsurface ocean, variability in the strength of the equatorial easterly trade winds, shifts in the position of atmospheric convection, and global teleconnection patterns associated with these changes that lead to variations in rainfall and weather patterns in many parts of the world,» which end up affecting «ecosystems, agriculture, freshwater supplies, hurricanes and other severe weather events worldwide.»»

This new concept of anthropogenic impacts on seawater pH formulated here accommodates the broad range of mechanisms involved in the anthropogenic forcing of pH in coastal ecosystems, including changes in land use, nutrient inputs, ecosystem structure and net metabolism, and emissions of gases to the atmosphere affecting the carbon system and associated pH. The new paradigm is applicable across marine systems, from open - ocean and ocean - dominated coastal systems, where OA by anthropogenic CO2 is the dominant mechanism of anthropogenic impacts on marine pH, to coastal ecosystems where a range of natural and anthropogenic processes may operate to affect pH.

Accordingly, there are three main vectors of anthropogenic impacts on marine pH: (1) emissions of CO2, and other gases affecting marine pH, to the atmosphere; (2) perturbation of watershed processes affecting the inputs of nutrients, organic and inorganic carbon, acids and carbonate alkalinity to the ocean; and (3) impacts on ecosystem structure (Table 1).
