Corals face in our modern world, a great threat due to a projected change in water chemistry in the ocean due to global warming. Just as carbon dioxide (the main greenhouse gas causing global warming) is increasing in the air, it also increases in seawater in its dissolved form. That makes seawater more acidic which, in turn, may slow the rate at which corals build their calcium carbonate skeletons.
