“Given the term “ocean acidification,” you’d expect current pH levels to be well under 7. But in fact, mainstream estimates of the average pH of our current oceans are about 8.1—estimated to have declined from 8.2 in preindustrial times—very much in the alkaline range. Thus we are witnessing very slow ocean “neutralization,” not “acidification”—acidification is a completely unscientific term used to scare us.”
