“Fuel on the Fire”: WMO Issues Urgent Global Warning to Prepare for El Niño

The science is definitive, and the countdown has officially begun.

The World Meteorological Organization (WMO) has issued a major press release announcing that El Niño conditions are actively developing in the tropical Pacific. This naturally occurring climate powerhouse is poised to fundamentally disrupt global weather patterns, spike temperatures, and trigger extreme weather events across the globe in the coming months.

As UN Secretary-General António Guterres bluntly stated: “El Niño conditions will pour fuel on the fire of a warming world. Impacts will hit even harder, travel even farther, and cross borders with devastating speed.”

Here is a breakdown of what the WMO data says, what changes are coming, and why the time for global preparedness is right now.

The Data: A Rapidly Escalating Threat

According to the latest consensus models from the WMO, the arrival of El Niño is no longer a matter of “if,” but “how strong.” The critical metrics reveal an urgent timeline:

• 80% Probability: There is an 80% likelihood of a full El Niño event establishing itself between June and August 2026.
• 90% Continuity: The probability that these conditions will persist through at least November 2026 is at or above 90%.
• Subsurface Intensity: The surface warming is being actively fed by an immense reservoir of heat beneath the ocean surface. Deep tropical Pacific ocean temperatures are registering a staggering 6°C above average.
• Moderate to Strong: While its exact peak remains to be seen, global forecast models project this event will be at least moderate, with a high potential to become a strong climate event.

A Double-Edged Sword: Typical Regional Impacts

El Niño shifts the jet stream and redistributes heat and moisture globally, bringing drastically opposite climate crises to different corners of the world. For the upcoming season, the WMO highlights two primary threats:

1. Severe Droughts, Heatwaves, and Wildfires

Where El Niño suppresses rainfall, it bakes the land. The WMO warns of drier-than-normal conditions and severe heat stress hitting:

• Central America and northern South America
• The Caribbean and Australia
• Indonesia and key agricultural zones in Southern Asia
• The northern Greater Horn of Africa, which faces a critical deficit during its vital June–September rainy season.

2. Torrential Rainfall and Flash Flooding

Conversely, the warming of the Equatorial Pacific pumps massive moisture into the atmosphere, raising the risk of severe flood disasters in:

• Southern South America
• The southern United States
• Parts of the Horn of Africa and Central Asia.

Additionally, while El Niño’s warm waters are expected to fuel hurricanes in the central and eastern Pacific, they historically hinder hurricane formation in the Atlantic. As a result, NOAA is forecasting a below-normal Atlantic hurricane season.

“Universal Dominance” of High Temperatures

Perhaps the most alarming takeaway from the WMO’s Global Seasonal Climate Update is the forecast for sheer, baseline heat. For the June–August period, models project a nearly universal dominance of above-normal temperatures across almost the entire planet.

Human-caused climate change does not necessarily make El Niño happen more often, but it acts as an amplifier. Because our oceans and atmosphere are already trapped in a warming trend, this El Niño has access to unprecedented amounts of energy and moisture, compounding the threat of severe marine heatwaves and prolonged land-based heat stress.

The Call to Action: Preparation Saves Lives

Climate anomalies on this scale severely disrupt climate-sensitive sectors like agriculture, water management, healthcare, and energy grids. WMO Secretary-General Celeste Saulo highlighted that the global community must learn from past events—noting that the powerful 2023–24 El Niño was a driving factor behind 2024’s record-shattering global warmth.

“Advance seasonal forecasts and early warnings are vital to save lives and cushion the impact on our economies and our communities,” Saulo noted.

The message from the United Nations and the WMO is clear: we cannot prevent an El Niño, but through early warning infrastructure, informed government planning, and immediate humanitarian mobilization, we can prevent it from becoming a global humanitarian tragedy. The window to prepare is open right now—and the world must act before the heat peaks.
