Atmospheric carbon dioxide concentration is expected to exceed500 parts per million and global temperatures to rise by atleast 2°C by 2050 to 2100, values that significantly exceedthose of at least the past 420,000 years during which most extantmarine organisms evolved. Under conditions expected in the 21stcentury, global warming and ocean acidification will compromisecarbonate accretion, with corals becoming increasingly rareon reef systems. The result will be less diverse reef communitiesand carbonate reef structures that fail to be maintained. Climatechange also exacerbates local stresses from declining waterquality and overexploitation of key species, driving reefs increasinglytoward the tipping point for functional collapse. This reviewpresents future scenarios for coral reefs that predict increasinglyserious consequences for reef-associated fisheries, tourism,coastal protection, and people. As the International Year ofthe Reef 2008 begins, scaled-up management intervention anddecisive action on global emissions are required if the lossof coral-dominated ecosystems is to be avoided.
