A commenter made the following reflection:
Ocean acidification is different than sea level rise and global warming, however. With ocean acidification, we're making an excursion unlike anything the planet has seen in 300 million years. There's simply no precedent that allows us to say "yeah, it's gonna hurt, but the world has already shown that it can cope with this kind of thing". It hasn't. As far as we know, this level of OA could produce a full trophic collapse -- and that isn't something that even I can't be cavalier about, as it would certainly be a civilisation-limiting (and possibly complex-life-limiting) event. Until we know for certain that the impacts of OA will be less severe than this, we should be doing everything we can to stop and reverse it.
I did High School chemistry. To me it seems that if you have something that is too acidic, then you change the pH by adding a basic (base) solution. (Albeit the reaction may cause some warmth).
But this feels like it is missing something that smarter people than me have spent time thinking through.
My question is: What is the evidence it is feasible to reverse ocean acidification by adding large quantities of a base (bicarb soda)?
