Exactly what is ocean acidification?Our oceans absorb about a quarter of the carbon dioxide that humans produce by burning fossil fuels each year, and that's changing their basic chemistry. This is particularly bad for creatures with calcium carbonate in their shells or skeletons, like mollusks, crabs, and corals. Acidic water makes it harder for them to grow those shells, so many of them are going to have a hard time surviving as our seas change.

Without zooxanthellae, corals turn white because zooxanthellae give corals their color. White, unhealthy corals are called bleached. Bleached corals are weak and less able to combat disease

# data[].attributes.body
Warmer water temperatures brought on by climate change stress corals because they are very sensitive to changes in temperature. If water temperatures stay higher than usual for many weeks, the zooxanthellae they depend on for some of their food leave their tissue.

when water temperature warms, corals will expel algae living in their tissues causing the coral to turn white

hurricanes and cyclones can break apart or flatten coral heads, scattering their fragments
