# Long description

This is contains a colour coded global map showing changes in ocean pH for the RCP8.5 scenarios. It shows that there is a reduction in pH (acidification) over most of the world's oceans. The map also indicates: Regions of mollusc and crustacean fisheries in many coastal regions (particularly North America, South America, India and East Asia. Regions of cold water corals, particularly in the fringes and middle of the north Atlantic and between Australia and New Zealand Regions of warm-water corals, including the oceans of Central America, and in an equatorial band across most of the Pacific and around the islands of south east Asia. Many of the highlighted regions are found in regions of large decreases of pH.

The figure also includes bar charts indicating the numbers of species in various groups, in a range of RCP scenarios (RCP4.5, RCP 6.0 and RCP 8.5, in order of increasing magnitude) Molluscs - negative effects on about 50% of species for all scenarios. Crustaceans - no effects or positive effects for the lightest scenario, increasing up to negative effects for 20% of species in the most sever scenarios. Cold water Corals - increasing number of species experiencing negative effects as the scenarios get worse. Warm water Corals - between 25 and 50 % of species affected, rising as the scenarios get worse.
