Why aren't all the fish dead? Willis Eschenbach on marine biology

See also Update 2 below.

Deniers at WUWT are busy protesting ocean acidification right now. Since 23 December there have now been five protest articles, four of which were arguably defamatory.  That's not including the silly WUWT articles on OCO-2, some of which are of peripheral relevance to the subject.

I've written a couple of articles about this latest spate of protests already (here and here), and at the risk of overloading on one topic, I couldn't resist another. Wondering Willis Eschenbach is so full of it.

Today Willis goes berserk. He's written one of the silliest articles I've read in a while at WUWT. He's pretending to be an expert on marine biology. His qualifications? He goes fishing sometimes. Well one thing is for sure, he might be able to catch and kill fish, but he certainly knows nothing about the biology and chemistry of the oceans.
