    3. 3. IMPACT
    4. 4. Coastal Flooding in the Caribbean “Loss of livelihoods, coastal settlements, infrastructure, ecosystem services, and economic stability (high confidence)” Source: IPCC AR5 WG II Ch. 29.6, 29.8
    5. 5. Source: IPCC AR5 Fig. CR1 Temperature and pH effects on coral reefs “Decline and possible loss of coral reef ecosystems in small islands through thermal stress (high confidence)” Source: IPCC AR5 WGII Ch. 29.3.1.2
    6. 6. 8 An Example of storm surge in the Caribbean “The interaction of rising global mean sea level in the 21st century with high- water-level events will threaten low-lying coastal areas (high confidence)” Source: IPCC AR5 WG2 Ch. 29.4, Table 29-1; WG1 13.5, Table 13.5
    7. 7. ADAPTATION
    8. 8. Health Insect vectors and infectious diseases increase eg. Zika, Chikungunya, Dengue Agriculture Crop yields decrease Irrigation demands increase Watershed Management Decrease in water supply Coastal Areas Erosion of beaches (loss of coral reefs). Inundation of coastal wetlands. Costs to protect coastal communities Natural Areas and Wildlife Change in forest composition Shift geographic range of forests Loss of habitat and species Sea Level Rise Temperature Precipitation Tropical Storms Potential Climate Change impacts Climate Change 10 Possible Climate Change Adaptation Measures Health Prevent mosquito access to standing water Agriculture Plant more drought tolerant varieties of crops Watershed Management Reduce water leakage from underground pipe supply network Coastal Areas Replant and restore mangrove wetlands and coral reefs Forests Restore degraded forest for Carbon sequestration Infrastructure Damage to infrastructure from increased intensity of Tropical Storms Infrastructure Improve and enforce National Building Codes
