The world could soon face another wave of climate-related challenges as the United Nations’ weather agency warns that El Niño conditions are rapidly developing and are expected to strengthen in the coming months.
According to the World Meteorological Organization (WMO), there is now an 80 percent probability that El Niño will emerge between June and August. Scientists say the climate phenomenon, driven by unusually warm waters in the tropical Pacific Ocean, has the potential to disrupt weather patterns across the globe, bringing higher temperatures, droughts, floods, and other extreme weather events.
The Geneva-based agency revealed that forecasts from its global climate monitoring network show a strong shift toward El Niño conditions, with confidence levels continuing to rise. Experts also estimate that the likelihood of El Niño being firmly established by November is close to or above 90 percent.
What Is El Niño?
El Niño is a naturally occurring climate pattern characterized by warmer-than-average sea surface temperatures in the central and eastern Pacific Ocean. These changes influence atmospheric conditions worldwide, affecting rainfall, wind systems, and temperature patterns.
The phenomenon generally occurs every two to seven years and can last anywhere from nine months to over a year. It alternates with La Niña, its cooler counterpart, with neutral conditions often occurring in between.
Climate models currently suggest that the upcoming El Niño event could be moderate to strong, raising concerns among climate experts and governments worldwide.
Increased Risk of Extreme Weather
WMO Secretary-General Celeste Saulo emphasized that countries should prepare for potentially significant impacts.
She noted that El Niño could worsen drought conditions in some regions while increasing heavy rainfall and flooding risks in others. Heatwaves on land and across the oceans are also expected to become more frequent and intense.
Even moderate El Niño events have historically increased the likelihood of climate and weather extremes. The last significant El Niño played a major role in driving global temperatures higher, contributing to some of the warmest years ever recorded.
Recent observations indicate that sea-surface temperatures in key monitoring areas of the Pacific Ocean are already approaching El Niño thresholds. Scientists have also detected unusually warm subsurface ocean temperatures, further supporting forecasts that El Niño conditions are developing.
Climate Change Could Amplify the Impact
While the WMO states there is currently no evidence that climate change directly increases the frequency or strength of El Niño events, experts warn that global warming can magnify their consequences.
A warmer atmosphere and ocean provide more energy and moisture for weather systems, increasing the severity of heatwaves, intense rainfall, flooding, and other climate-related disasters.
United Nations Secretary-General Antonio Guterres described the situation as an urgent warning for the global community.
He stressed that El Niño could add further pressure to an already warming planet, causing impacts that spread faster, affect more people, and cross borders with increasing intensity.
Guterres also called for stronger climate action, including reducing dependence on fossil fuels, accelerating renewable energy adoption, protecting vulnerable populations, and expanding early warning systems worldwide.
Global Temperature Concerns Continue to Rise
Forecasts for June through August suggest that above-average temperatures are likely to dominate across most regions of the world.
Climate experts warn that prolonged heat can create compounding risks, including water shortages, crop failures, increased wildfire activity, and public health emergencies.
Several regions are already expected to experience weather disruptions:
The Greater Horn of Africa could face below-normal rainfall during its crucial rainy season.
South Asia may see weaker monsoon activity than usual.
Central America is expected to experience warmer and drier conditions.
The Pacific hurricane season could become more active, while Atlantic hurricane development may be somewhat suppressed.
Agriculture, Water, Energy, and Health at Risk
The WMO believes that early warnings can help governments, businesses, and communities prepare for potential disruptions.
Industries most vulnerable to El Niño impacts include agriculture, water resource management, energy production, healthcare, and disaster response systems.
Farmers may need to adjust planting schedules, water authorities could face increased pressure to manage scarce resources, and health systems may need to prepare for heat-related illnesses and disease outbreaks associated with changing climate conditions.
Why This Matters to Everyone
While El Niño is a natural climate cycle, its arrival comes at a time when the planet is already experiencing record-breaking temperatures and increasing climate stress.
For millions of people around the world, the effects may not simply be higher temperatures. They could include rising food prices, water shortages, disrupted livelihoods, increased energy costs, and greater exposure to natural disasters.
The warning from the United Nations is not just a scientific forecast—it is a reminder that preparedness, resilience, and climate action are becoming more important than ever. Communities, businesses, and governments that act early will be better positioned to reduce risks and protect lives as the world enters another potentially challenging climate season.
