Coral reefs threatened by a deadly combination of changing ocean conditions

The lowering of the ocean's pH is making it harder for corals to grow their skeletons and easier for bioeroding organisms to tear them down. Erosion rates increase tenfold in areas where corals are also exposed to high levels of nutrients, according to a new study. As sea level rises, these reefs may have a harder time growing toward the ocean surface, where they get sunlight they need to survive.
