"Far from the oceans acidifying, their pH currently ranges between 7.9 and 8.3, putting them very firmly on the alkaline side of the threshold, at 7.0."This is just unbelievably stupid. I can't even believe even Booker thinks this is an accurate description of ocean acidification, which is, of course, about the ocean's pH getting lower, regardless of its starting point.
As others have noted, "ocean acidification" is not perhaps the most compelling term, especially in a scientifically illiterate world that seems to need every little detail spelled out. But Booker's statement is akin to saying that a temperature increase from -10°C to -5°C isn't "warmer" because it's still below the freezing point.
