The Greater Caribbean is one of the world’s most climate-vulnerable regions, where rising risks threaten to uproot communities, deepen poverty, and reshape migration patterns. The Greater Caribbean Climate Mobility Initiative (GCCMI), launched in 2022, is charting a new path for climate-resilient development in one of the world’s most climate-vulnerable regions. By addressing the urgent challenge of climate-forced displacement and migration, the Initiative brings together governments, international organizations, and research leaders to co-design comprehensive, locally anchored solutions.
