It’s just more climate catastrophising. CaCO3 and H2CO3 form a buffer that would minimise the effects of acidification. The idea that all fish would die is dumb. Terrestrial plants produce oxygen by photosynthesis so oxygen won’t disappear from the atmosphere.
“lifting the calcium carbonate compensation depth”
Wouldn’t increased CaCO3 dissolution increase pH? I’m surely misunderstanding you — presumptively there’s less compensation allowing more CO2 / carbonic acid?
I’m out of my depth…
