Caribbean Urged to Prepare for Hotter, Drier Conditions as El Niño Develops

The Caribbean is on high alert as a developing El Niño is poised to bring significantly hotter and drier conditions to the region over the next two years. Climatologists and meteorologists are issuing urgent warnings, calling on governments, businesses, and communities to brace for the potential impacts of this potent climate pattern.

This El Niño event is likely to bring periods of reduced rainfall and increased humid heat, which can affect water availability and agriculture, and increase the likelihood of heat stress and dry conditions.

Dr. Cedric Van Meerbeeck of the Barbados-based Caribbean Institute of Meteorology and Hydrology (CIMH) highlights the dual threat of reduced rainfall and increased humid heat. This combination poses serious risks to crucial sectors like agriculture and water resource management. Areas already grappling with drought may face prolonged recovery periods, exacerbating existing vulnerabilities.

Professor Michael Taylor from the University of the West Indies (UWI) adds a critical layer of concern, pointing to the emergence of a 'multi-hazard regime.' This means that heat, drought, and marine impacts like coral bleaching could occur simultaneously, amplifying their destructive potential. The UWI and CIMH stress that such compound extremes are a grave threat to the livelihoods and well-being of Caribbean people.

What we are seeing in the forecasts is the emergence of a potential multi-hazard regime—where heat, drought, and marine impacts can occur together and reinforce each other.

While El Niño often correlates with quieter Atlantic hurricane seasons, the warning is clear: the risk of severe weather events, though potentially less frequent, remains. The historical examples of Hurricane Andrew and Tropical Storm Erika serve as potent reminders that even a single event can inflict devastating damage. The interconnected nature of these climate risks demands a robust, coordinated regional response, emphasizing preparedness across all sectors to safeguard the future of the Caribbean.

Our research has long pointed to these compound extremes as a serious threat to life and livelihoods in the Caribbean. With advance warning of a looming multi-hazard threat, preparedness is imperative—requiring coordinated and integrated action across and within sectors and a strong regional approach.
