Alas, even the Wall Street Journal carries badly distorted stories. I just read this one (and made several comments) before reading your latest: "Earth Just Had Its Hottest Month Ever. How Six Cities Are Coping." HOTTEST EVAH!
"It may well be true that pteropods function less well when their environment becomes less basic but it is not because they are now in an acid bath."
My understanding is, you need to be in a supersaturation of calcium carbonate to form a shell. If you can't form a shell, you are about as well placed as a human embryo which can't form a skeleton. So if you are a pteropod, an environment which is just alkaline but slightly less so to a human, can indeed be an acid bath. Or if that's an exaggeration, it's a pardonable exaggeration if its effect is to make you extinct.
pH varies through the day. It's lower around river outlets. It get higher when water warms. The water around ocean vents are acidic. pH varies by location as well. pH is lower in the arctic oceans and higher in the tropics.
This is similar to sea level rise, which can be due to land subsidence or rise and varies by location. It also varies in short term intervals so that it can look like it's accelerating or decelerating depending on the time period chosen.

How did they get an average pH for the oceans?

>It is possible that I am mistaken
Yeah, I think you are. It is all about "fear sells." It is all for clicks / $, not politics.
IMHO.
Also IMHO, I would cut the horse stuff. The rest of the column is (again, IMHO) much stronger.
I like the shrinking horse anecdote.
Me, too.
