Two leading Caribbean climate research institutions, the Caribbean Institute of Meteorology and Hydrology (CIMH) and the University of the West Indies Climate Studies Group Mona (UWI CSGM), have issued an urgent early call for regional governments, private enterprises, agricultural producers and households to implement proactive preparations for extreme climate events. Forecasters project a developing El Niño will bring prolonged hotter, drier conditions across the Caribbean throughout 2026 and 2027, bringing cascading, compound climate risks that threaten lives, livelihoods and regional economies.
