Earth System Models project that, within the last decade, ocean acidity exceeded historical analogues
[9] and, in combination with other ocean
biogeochemical changes, could undermine the functioning of marine ecosystems and disrupt the provision of many goods and services associated with the ocean beginning as early as 2100.

Increasing acidity is thought to have a range of potentially harmful consequences for marine organisms, such as depressing metabolic rates and immune responses in some organisms, and causing
coral bleaching.
