Temperature increase effects

1. Sea ice loss - Loss of habitat, Unpredictable consequences. 2. Sea Level Rise. 3. Higher stratification - Higher temperatures in surface seawater enhances the thermocline and hence, less nutrient upwelling… decrease in primary productivity in certain areas of the ocean. 4. Changes in currents. 5. Heat content - Total ocean heat content rising - 2 consequences: Warming in irregular patches, species shift pole-wards, Rising Accumulated Cyclone Energy. 6. Spawning errors (asynchrony). 7. Marine diseases
