The United Nations has issued a strong warning to countries worldwide to prepare for a possible surge in extreme weather events as a new El Niño pattern is expected to develop in the coming months. The alert highlights growing concerns over heatwaves, drought conditions, floods, and intensified storm activity across multiple regions.
High Probability of El Niño Formation This Year
According to the World Meteorological Organization (WMO), there is an estimated 80 percent likelihood of El Niño conditions emerging between June and August, with the probability rising to nearly 90 percent by November. The phenomenon, driven by unusual warming of Pacific Ocean surface waters, typically disrupts global weather systems for months at a time.
UN officials have warned that the developing pattern could be “moderate to strong,” increasing the risk of climate extremes in both hemispheres. El Niño events usually occur every two to seven years and are known to significantly alter rainfall, temperature, and wind behavior worldwide.
Global Regions Face Opposite Climate Impacts
The WMO explained that El Niño does not affect all regions equally. While parts of South America and North America may experience heavier rainfall, countries in South Asia, Indonesia, Australia, and Central America often face below-normal rainfall and prolonged drought conditions.
Experts caution that such imbalances could strain agriculture, water supplies, and food security systems, particularly in developing nations already vulnerable to climate stress. Rising temperatures also increase the risk of forest fires and heat-related illnesses.
Climate Stress and Secondary Risks Increase
UN Secretary-General António Guterres has urged governments to treat the warning as an urgent signal for preparedness. He noted that extreme weather patterns are becoming more destructive and less predictable, with impacts that can quickly cross borders.
Climate researchers have also warned that El Niño conditions may intensify wildfires and heatwaves, especially in already warm regions. In recent years, similar patterns have contributed to record-breaking global temperatures and widespread environmental disruptions.
Health experts further caution that shifting climate conditions could encourage the spread of mosquito-borne diseases such as dengue and malaria, particularly in tropical regions where temperature and humidity levels become more favorable for vector growth.
Economic and Food Security Concerns
Beyond environmental risks, El Niño could also affect global food production. Crop yields in major agricultural regions may decline due to irregular rainfall, potentially pushing up prices of commodities such as grains, cocoa, and edible oils.
Industries dependent on stable agricultural supply chains are already monitoring the situation closely, as even moderate disruptions can lead to global price volatility.
Call for Preparedness and Climate Action
The UN has reiterated the importance of strengthening early warning systems, disaster preparedness, and climate adaptation strategies. Officials have also emphasized the long-term need to reduce dependence on fossil fuels, noting that climate change is amplifying the severity of natural weather cycles like El Niño.
As the world awaits confirmation of the pattern’s full development, scientists stress that early action could significantly reduce the human and economic cost of the expected weather extremes.
