New Scientist: COULD corals survive ocean acidification against the odds? That's the hope raised by reefs found to be thriving in naturally acidified waters. Corals use the carbonate ions in water to build their skeletons from calcium carbonate. But ocean acidification caused by climate change reduces the available carbonate ions. Lab studies suggest that this leaves corals unable to grow and survive. The few known reefs living in naturally acidified water also tend to be unhealthy. So Kathryn Shamberger of the...
