That is definitely my biggest worry ocean-wise. I haven’t read many acidification papers but the impression I get is that ocean absorption of CO2 is relatively slow so we will only start to see noticeable changes on the order of centuries. If these problems occur faster than we can decarbonise then we will need to geoengineer ocean chemistry. Although this is a plan B, we will be able to implement it before there are significant enough changes to cause a collapse.
