A pH change of .24 of the oceans is definitely cause for concern. However, the natural pH of seawater is 8.2, well into the alkaline range, and reducing that by something between .24 and .45 would mean that the ocean were still in the alkaline range (though quite worryingly less). So the headline here
As to the suggestion that the pH will be lowered by as much as .35, it comes from the IPCC, so caveat lector.
