pH is the negative logarithm of the hydrogen ion concentration, so the relationship between the acid concentration and the pH is not linear. However, the article states that the pH level will change by certain percentages, not that the acid concentration will change by certain percentages.
On Ocean Acidification Eats Oysters

There is some serious fail in this article
" Dewey, who explained that burning fossil fuels has upped the pH level by 30 percent in the last 200 years, with a 150 percent change on tap by the end of this century."
The stronger the acid, the lower ph. So, as the ocean acidifies the ph would not be upped, it would be lowered.
It is estimated that the ocean ph has changed from 8.25 to 8.14 over the last 200 years. By my math that is a 1.3% decrease, not a 30% increase.
The current ocean surface ph is 8.14, if it were increased by 150% in the next century the ocean ph would then be 20.35. The highest possible ph in water is 14.
The issues this article is attempting to address are severely undermined by its inaccuracies.
