Acid oceans DISSOLVING sea life

David Friedman

The Oceans are not Acid

The title of your story is flatly false. The pH of the ocean, the measure of acidity, is above 7, meaning that it is basic, not acidic. "Acidfication" does not mean that the ocean is becoming acidic but that it is becoming less basic, nearer to neutral.

That does not mean that it isn't a problem--sea life adapted to a basic environment may have problems in one that is less basic. But the way your story puts it makes it look as though we can shortly expect to go into the ocean and have our skin eaten away by acid, which is almost exactly the opposite of what is happening; both acids and bases are corrosive and the ocean is becoming less basic.
