Global warming is largely caused by increased atmospheric concentrations of greenhouse gases, particularly CO₂, resulting from human activities. The ocean acts as a significant sink for atmospheric CO₂, absorbing about a quarter of the anthropogenic emissions. When CO₂ dissolves in seawater, it reacts with water to form carbonic acid (H₂CO₃). Carbonic acid then dissociates, releasing hydrogen ions (H⁺), which lowers the pH of the water, making
It is reported that there is an ongoing decrease in the pH value of ocean water because of global warming. It happens due to :
