A global analysis of coral bleaching over the past two decades SST in Kelvin. Corals are affected by ocean warming (sometimes bleaching when temperatures rise or fall), by pollution and runoff, and by changes in the pH of seawater, which decreases as more carbon dioxide enters the oceana trend known as ocean acidification. Corals are naturally white. The accelerated pace at which ocean temperatures have risen since the 1980s is causing coral bleaching and contributing to widespread loss of reef ecosystems. .infographic-wrapper { Although this has slowed global warming, it is also changing ocean chemistry. 11, 133146 (1984). SSTA_DHWMean: CoRTAD. As corals grow, they form skeletons by making calcium carbonate from the ocean waters. Bleaching is an estimate of the number of bleached coral colonies relative to the number of colonies that are not bleached at a given site (i.e., site-wide bleaching).
