Apparently these sensitive snails are dissolving p <because> they are in an alkaline ocean of around pH 8.14. Amazing. The paper does not point out that some parts of the ocean naturally vary in pH by 1.4 units. Of course none of the massive amounts of chemical junk dumped into the oceans and poisoning the fish we eat, has any effect on these snails. Did they check?
“This natural variability has prompted the suggestion that “an appropriate null hypothesis may be, until evidence is obtained to the contrary, that major biogeochemical processes in the oceans other than calcification will not be fundamentally different under future higher CO2/lower pH conditions””
