"Carbon dioxide is an acid gas. It reacts with water to form carbonic acid. And then that carbonic acid completely disassociates, it forms a a hydrogen ion and bicarbonate, and in doing so, it reduces the pH of seawater. Since the beginning of the Industrial Revolution, that pH change has been about 0.1 pH units, which is a 30% rise in hydrogen ion concentration. A 30 % rise in acidity of the surface ocean."
