'Projected warming increases the risk of greater thermal stratification in some regions, which can lead to reduced O2 ventilation  and the formation of additional hypoxic zones, especially in the Baltic and Black seas .' 'Changing rainfall intensity can exert a strong influence on the physical and chemical conditions within SES, and in some cases will combine with other climatic changes to transform these areas. These changes are likely to increase the risk of reduced bottom-water O2 levels to Baltic and Black Sea ecosystems , which is very likely to affect fisheries.' Persian Gulf, Red Sea: 'Extreme temperature events, such as heat waves, are projected to increase   temperatures are very likely to increase above established thresholds for mass coral bleaching and mortality .'
