On October 21, two UN agencies did something they rarely do together: the World Meteorological Organization (WMO) and the UN Office for the Coordination of Humanitarian Affairs (OCHA) held a joint emergency press conference in Geneva.
The message was blunt.
The numbers behind the warning
According to the WMO's latest Global Seasonal Climate Update, sea surface temperatures in the tropical Pacific — the epicenter of El Niño — could reach 3.8°C above average between November 2026 and January 2027.
For context: an anomaly of just 0.5°C is enough for the WMO to declare an El Niño event.
"The current El Niño event could be unprecedented in strength — literally off the monitoring charts that we have used for the past four decades," said WMO Secretary-General Celeste Saulo. "We are beyond that limit, out of our records, out of our statistics of what we can expect."
UN relief chief Tom Fletcher was equally direct, calling this El Niño "a behemoth… a wrecking ball that will likely tear through Latin America, eastern and southern Africa, Asia and the Pacific with extreme heat, droughts and floods."
What is already being done
The UN has released more than $50 million from its Central Emergency Response Fund to 11 frontline countries, including Chad, El Salvador, Ethiopia, Somalia and South Sudan.
The stakes, per the UN briefing:
- ~50 million people could face increased hunger
- The African Development Bank estimates African economies alone face $10–20 billion in losses, cutting regional GDP by 1–2%
- Impacts will be felt "for months and potentially years," compounded by existing supply chain stress in the Strait of Hormuz and the Black Sea
This is not a forecast about next decade. The UN explicitly framed the next several weeks as the critical window.
Why this matters for fresh produce
The regions named in the UN warning — Latin America, East Africa, Southeast Asia, the Pacific — overlap almost exactly with the geographies that supply a large share of the world's open-field fresh produce.
We have already seen the early signals this season:
- Drought emergencies across Central America's Dry Corridor
- Flooding displacing thousands in Paraguay, with the Paraná River at its highest level in over 40 years
- Drought-driven fires across parts of Southeast Asia
- Raw sugar futures up more than 25% since July as harvest forecasts in India, Brazil and Thailand were cut
Each of these is a supply chain story. Collectively, they describe a structural shift in the risk profile of open-field production.
The case for climate-resilient capacity
At Regulus, we work on controlled environment agriculture — greenhouses, vertical farms, and container farms that produce food independent of outside weather. For years, the commercial case for CEA rested on freshness, food miles and pesticide-free production.
Climate volatility is rewriting that case.
When a single weather system can put 50 million people at risk of hunger and erase $10–20 billion from a continent's economy, production that is insulated from weather stops being a premium niche. It becomes supply chain infrastructure.
The UN cannot stop El Niño. But food companies, retailers and governments can decide how much of their fresh supply depends on the weather.
The organizations making that decision now — before the peak hits between November and January — will be the ones with stable supply on the other side of it.

What this means for growers
For controlled environment agriculture, the implication is straightforward: the customers who need production decoupled from outside weather are exactly the ones building greenhouses, vertical farms, and container systems. Our work at Regulus is focused on that transition – growing modules, horticultural lighting, and environmental control that let a facility produce on schedule regardless of what the Pacific is doing.
