IMO the whole “ocean acidification” terminology is intentional scare mongering.
In actual fact the oceans are still quite basic and even the scare mongerers admit they will remain basic. Since the pH of the ocean remains on the basic side, it is inaccurate to refer to it as acidificaton.
The “adicification” they talk about, if it is occurring, which is debatable, is a slight decrease in the pH, bringing it a little closer to neutral. It would have to go past neutral to become acidic.
But acidification sounds so much more scary than “becoming slightly less basic.”
Well, if it's acidification - I get that!
Baking soda takes care of it :>))
