According to the study, released by the Convention on Biological Diversity (CBD) in collaboration with the United Nations Environment Program (UNEP), by 2050, ocean acidity could increase by 150 percent, 100 times faster than any change in acidity experienced in the marine environment over the last 20 million years.

As more and more carbon dioxide has been emitted into the atmosphere, the oceans have absorbed greater amounts at increasingly rapid rates, says the study. The absorption of atmospheric carbon has changed the chemical balance of the oceans, making them more acidic, which means that by the year 2100, some 70 percent of cold
