Corals require acid-sensitive calcium carbonate for structure and heat-sensitive symbionts for sustenance, so they seem to have the most to lose from a warmer, more acidic ocean. Indeed, numerous studies have already indicated that calcifying organisms, including corals, would be among the worst to suffer. Although many studies have looked at heat and acidification,...
