Key highlights from the report “State of the Climate in Latin America and the Caribbean 2025”, published by World Meteorological Organization (WMO) are:
- Temperatures remained well above average, with 2025 ranking among the fifth to eighth warmest years on record across Latin America and the Caribbean, at around +0.40 °C above 1991–2020 levels.
- Andean glaciers are losing mass at an accelerating rate with implications for long-term water security in the region. Sea levels are rising faster than the global average along the northern Atlantic coast of South America and across Central America and the Caribbean.
- Ocean acidification and ocean warming are ongoing across the region, with a continued decline in surface ocean pH and rising temperatures, compounding risks to marine ecosystems and fisheries.
- Hurricane Melissa became the first Category 5 hurricane on record to make landfall in Jamaica, leading to 45 deaths and economic losses of approximately 8.8 billion US dollars, more than 41% of GDP. Despite these impacts, successful prior risk modelling enabled both financial and policy preparedness in Jamaica.
- Extreme rainfall and flooding triggered major humanitarian impacts, including over 110 000 people affected in Peru and Ecuador, 83 deaths in Mexico, and widespread landslides and infrastructure damage.
- Prolonged and widespread drought affected large parts of the region, with up to 85% of Mexico impacted, severe water shortages in the Caribbean and over 40% rainfall deficits in parts of southern South America, contributing to agricultural losses and wildfire risk.
- Record-breaking heat extremes were observed across the region, including 52.7 °C in Mexicali, Mexico, as well as multiple heatwaves exceeding 40 °C–45 °C across Mesoamerica, and an all-time record of 37.2 °C in São Paulo, Brazil.
- As extreme heat events intensify, reducing avoidable mortality will depend on strengthening climate–health cooperation, improving mortality attribution and embedding climate intelligence into health planning and emergency preparedness across the region.
