When carbon dioxide is absorbed by the oceans, it makes the salt water more acidic. Ocean acidification makes it difficult for species which have body parts comprised of calcium carbonate, such as corals, crustaceans and shellfish, to grow. Increased water temperatures adds an additional pressure. Reducing CO2 in the atmosphere to below 350 parts per million (ppm) is critical for maintaining healthy coral reefs. However, we are currently at 386.8 ppm and levels will likely be 450 ppm by the middle of the century. It is essential that we do everything possible to reduce atmospheric CO2 levels and address all other threats to coral reefs to keep them as resilient as possible for the people and species that depend on them.
