Although this has slowed global warming, it is also changing ocean chemistry. Zooxanthellae are single-celled dinoflagellate microalgae that use photosynthesis to produce organic carbon (energy) in the form of sugars and other compounds. Ocean temperatures are predicted to continue to rise if we keep adding carbon dioxide and other greenhouse gases to the atmosphere. 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). The coral bleaching response index was published today (April 13) as an Early View article by the journal Global Change Biology. http:www.agrra.org/data-explorer/explore-summary-products/ (2018). One example, aimed at middle school teachers, is provided here. As carbon pollution is emitted into Earth's atmosphere, it traps heat and causes temperatures to rise. TSA_Standard_Deviation: CoRTAD.
