The ocean is not acidified, except in Jeremy's head. The ocean is still alkaline, with pH well above 7.0, which is neutral.

Surface ocean pH has declined about 0.1 pH units (globally) since accurate measurements commenced. That's "acidification", not "acidified".

‘Acidified’ is a loaded term that implies that the water is turning acidic. If the liquid were in the lab, ‘pH lowered’ or ‘neutralized’ would be used.
