WMO Warns Developing 'Super El Niño' Could Push 49 Million Into Acute Food Insecurity

A rapidly intensifying climate pattern in the Pacific Ocean is threatening to disrupt global food supplies and push millions of vulnerable people into crisis. The World Meteorological Organization and the United Nations World Food Programme have issued stark warnings that a developing El Niño event could become the strongest ever measured, potentially driving an additional 49 million people into acute food insecurity by the end of next year. The convergence of naturally occurring ocean warming and baseline climate change is creating a scenario that forecasters warn could devastate agricultural yields across multiple continents. As sea surface temperatures continue to climb well above historical averages, the window for preemptive humanitarian action is rapidly closing.[1][5]

The World Food Programme’s latest analysis indicates that the total number of people facing crisis-level hunger could rise to 274 million across 45 highly vulnerable countries. Jean-Martin Bauer, director of the agency's Food Security and Nutrition Analysis Service, noted that similar climate events in the past have consistently triggered large-scale hunger. The current trajectory suggests a 22 percent increase relative to the baseline population already experiencing severe food insecurity. This surge threatens to overwhelm international aid networks that are already strained by funding cuts and ongoing geopolitical conflicts, leaving millions of families without a safety net as their local food systems collapse.[1][2][4]

The mechanism driving this impending crisis is a dramatic and rapid warming of ocean surface temperatures in the central and eastern Equatorial Pacific. According to the World Meteorological Organization, multi-model ensemble forecasts indicate that seasonal-average sea-surface temperature anomalies could exceed 2.9 degrees Celsius in key monitoring regions between August and October 2026. This level of extreme warming would place the current event among the most powerful climate disruptions since modern record-keeping began in 1950. The sheer volume of heat accumulating in the Pacific alters atmospheric pressure and trade winds, effectively rewriting global weather patterns for the duration of the event.[5][6]

While the World Meteorological Organization officially avoids the term "Super El Niño"—preferring standard operational classifications like "moderate," "strong," or "very strong"—the sheer scale of the forecasted anomalies has prompted widespread use of the moniker among meteorologists and climate scientists. The agency has confirmed an 81 percent probability of a very strong event developing, which is expected to dominate global climate patterns and significantly alter rainfall distribution well into 2027. This shift typically brings devastating droughts to some regions while inundating others with torrential, flood-inducing rains, both of which are equally destructive to staple crops.[1][5]

The downstream consequences for global agriculture are expected to be severe, particularly in the Global South where subsistence farming is prevalent. The World Food Programme projects that Central America and Southern Africa will be the hardest-hit regions. Food insecurity is forecast to increase by a staggering 83 percent in Central America and nearly 75 percent in Southern Africa as the climate pattern brings prolonged, unyielding droughts that decimate local harvests. In these regions, the loss of a single growing season can plunge entire communities into famine, erasing years of economic development and agricultural progress.[1][2]

South America and the Caribbean are also highly vulnerable, with each region potentially seeing more than 12 million additional people fall into acute food insecurity. Máximo Torero, Chief Economist of the Food and Agriculture Organization, has warned of a "double blow" for Latin America. In this scenario, severe weather impacts will likely compound existing agricultural challenges, including reduced access to essential fertilizers and hybrid seeds due to ongoing global supply chain disruptions. This compounding effect means that farmers will have fewer tools available to adapt to the changing climate, virtually guaranteeing lower yields.[2][4]

The historical precedent for such an intense climate anomaly is grim. The exceptionally strong El Niño cycles of 1982-83, 1997-98, and 2015-16 caused tens of thousands of deaths, displaced millions of people, and inflicted trillions of dollars in economic damage worldwide. The 2015-16 event alone affected the food security of up to 100 million people, triggering repeated crop failures and massive livestock losses across East and Southern Africa. Experts warn that the current event could mirror or exceed these past disasters, exposing and deepening existing vulnerabilities across the globe.[3][7]

What makes the 2026 event particularly dangerous is its interaction with an already warming planet. The World Meteorological Organization notes that while El Niño is a naturally occurring cycle, it is now taking place against a backdrop of record-high global temperatures driven by human activity. This combination increases the availability of energy and moisture in the atmosphere, amplifying the severity and frequency of extreme weather events such as heatwaves, heavy rainfall, and prolonged droughts. The baseline warming effectively raises the floor for the disaster, meaning that even a standard El Niño would cause outsized damage.[5][6]

In response to the escalating threat, international bodies are urging immediate preemptive action to protect vulnerable populations. The United Nations has launched a $202 million anticipatory action appeal to aid 22 high-risk countries before the worst impacts materialize. Experts emphasize that investing early in resilient seeds, stronger transport infrastructure, and strategic harvest planning can significantly mitigate the damage. However, they warn that governments and aid organizations must act immediately, as the window to prepare agricultural systems for the impending climate shock is rapidly closing.[2][7]
