The impacts of climate change are increasingly severe and the need for action is more urgent than ever. Caribbean islands are among the world’s most vulnerable, with storm frequency and intensity, flooding, wind damage and sea level rise all predicted to worsen, increasing threats to hospitals, power plants, freshwater sources, roads, houses and schools. Island communities must work together to prepare for disasters caused by natural phenomenon and minimize the impacts they will endure. Evidence shows that key ecosystems, like coral reefs and mangroves, can help reduce these risks while enhancing sustainable economic development.
