Latin America and the Caribbean are facing a dire situation as extreme weather events threaten the lives and livelihoods of millions. The region is experiencing a perfect storm of heatwaves, floods, droughts, and rising sea levels, all of which are exacerbated by climate change. These events are not only devastating in the moment but also have long-lasting impacts on food production, healthcare systems, and access to clean water. It's time to take a closer look at the situation and explore the implications and potential solutions.
One of the most pressing issues is the threat to life and health. In 2025, temperatures soared above 40°C across large parts of the region, with a record-breaking 52.7°C in Mexico. Brazil and Paraguay also recorded temperatures above 44°C. Extreme heat is becoming a major public health threat, especially for vulnerable communities with limited access to healthcare, cooling, and reliable electricity. Many countries still do not routinely track heat-related deaths, but the report estimates around 13,000 people died annually from heat-related causes across 17 countries between 2012 and 2021. This is a stark reminder of the urgent need to address the health impacts of extreme heat.
Another critical issue is food insecurity. Increasingly extreme rainfall patterns are worsening humanitarian conditions across the region, with communities facing cycles of devastating floods and prolonged drought. In 2025, flooding affected more than 110,000 people in Peru and Ecuador, while floods in Mexico killed 83 people and caused widespread infrastructure damage and landslides. At the same time, severe drought affected up to 85% of Mexico, creating major water shortages for crops and reservoirs despite the country experiencing its wettest June on record. Water shortages were also reported across the Caribbean, while drought conditions in southern South America increased agricultural losses and wildfire risks. The WMO warned that worsening climate extremes are placing growing pressure on agricultural production and food processing (agro-food) systems, threatening livelihoods, food access, and rural communities across the region.
The situation is further complicated by the rapid retreat of glaciers across the Andes. These glaciers provide freshwater for nearly 90 million people, supporting drinking water, agriculture, hydropower, and industry. However, glaciers across Colombia, Ecuador, Peru, Chile, and Argentina are melting at accelerating rates, increasing the risk of both flooding and long-term water shortages. The signs of a changing climate are unmistakable across Latin America and the Caribbean, said WMO Secretary-General Celeste Saulo, warning of accelerating glacier loss, rising sea levels, tropical cyclones, floods, and drought. The State of the Climate in Latin America and the Caribbean 2025 is not only a scientific publication but also a call to action, she says.
The report also highlighted the growing danger posed by rapidly intensifying storms. Hurricane Melissa became the first Category 5 hurricane on record to make landfall in Jamaica in October 2025, killing 45 people and causing economic losses equal to more than 41% of the country's GDP. Meanwhile, rising sea levels and warming oceans are increasing risks for coastal communities, fisheries, and marine ecosystems across the Caribbean and Atlantic coasts. Sea levels in parts of the tropical Atlantic and Caribbean are rising faster than the global average. WMO officials warned that without urgent investment in climate adaptation, disaster preparedness, and early warning systems, humanitarian needs across the region will likely only get worse.
In conclusion, the situation in Latin America and the Caribbean is dire, and the impacts of extreme weather events are far-reaching. From heatwaves to floods, droughts to rising sea levels, the region is facing a multitude of challenges that threaten the lives and livelihoods of millions. It's time for governments, organizations, and individuals to come together and take action to address the root causes of these issues and build resilience against the impacts of climate change. The future of the region depends on it.
