For 10 points, name this "evil twin" of global warming in which dissolved CO2 is decreasing the pH of Earth's waters.
This process is studied by scientists using FOCE experiments. Resistance to this process can be quantified using the Revelle factor. The relative presence of various species involved in this process normalized by the total DIC is depicted on a Bjerrum plot. The growth patterns of Mytulis edulis and Pisaster ochraceusi are altered by this process. This process causes the aragonite saturation horizon to rise, leading to a decrease in (*) calcification. Iron fertilization is thought to be able to slow this process, which exacerbates the progress of coral bleaching. Its causative mechanism is the fact that carbonic acid dissociates to form a bicarbonate ion and a free proton.
