OCHA Daily Briefing: Fletcher Calls El Niño a 'Wrecking Ball' With Two Weeks to Act

The UN's humanitarian chief used a Geneva appearance alongside the head of the World Meteorological Organization to press for a far wider mobilisation against El Niño, describing the climate pattern as a "behemoth" and a "wrecking ball" and arguing that the coming fortnight is decisive. The remarks were carried in the UN Office for the Coordination of Humanitarian Affairs (OCHA) daily news round-up published on 21 October 2026.

'We cannot prevent El Niño'

Tom Fletcher, the Under-Secretary-General for Humanitarian Affairs and Emergency Relief Coordinator, said El Niño will strike regions that are already contending with conflict, displacement, high food, fertilizer and fuel prices, and large reductions in aid funding, according to OCHA's account of his remarks. He spoke with Celeste Saulo, the Secretary-General of the World Meteorological Organization.

Fletcher's central argument, as reported by OCHA, was that the humanitarian system cannot absorb a shock of this size by itself. He called for a much broader mobilisation of solidarity, expertise and action spanning governments, civil society, academia and the private sector.

He also attached a deadline to that appeal. OCHA reported that Fletcher described the next two weeks as a critical window to act before the damage is done, and said that because forecasts give advance notice, failing to use the opportunity to protect people in El Niño's path would be an "extraordinary failure".

"We cannot prevent El Niño," Fletcher said in remarks quoted by OCHA. "But we can be serious about the challenges ahead, and we can be creative and generous in preparing for them."

The round-up does not attach index values, probabilities or regional forecast figures to the warning; it reports the relief chief's appeal rather than a technical outlook. Readers tracking the underlying ocean and atmosphere indicators can follow agency updates collected in our news archive.

The rest of the briefing

The El Niño item led an OCHA bulletin that also covered five conflict and violence emergencies, each with its own figures.

In Yemen, OCHA said fighting has forced nearly 260,000 people from their homes since the start of August, with close to half sheltering in Ta'iz governorate. The UN Human Rights Office (OHCHR) has verified 251 civilian casualties — 57 people killed and 194 injured — with half of those killed being children, OCHA said. Humanitarian partners have reached more than 174,000 displaced people since August, nearly six in ten displaced households, with food, hygiene kits and emergency cash; shelter is the most pressing need reported by newly displaced families, followed by food and cash.

In Gaza, OCHA said it remains deeply concerned about continued strikes reportedly causing civilian casualties and affecting aid operations, and reported that a UN convoy in Khan Younis rerouted after small-arms fire landed nearby. The UN delivered food, fuel and about 900 pallets of winter clothing and school supplies, while child protection partners distributed 4,200 winter clothing kits and provided psychosocial counselling or consultations to nearly 6,000 children. Mine action partners conducted 30 explosive-hazard assessments and reached nearly 17,000 children and adults with risk-awareness sessions between 7 and 15 October, but OCHA said they still lack the permissions needed to clear ordnance.

On the West Bank, OHCHR called on States and donors to take urgent action to protect Palestinian communities during the olive harvest, citing movement restrictions and attacks on harvesters.

In Ukraine, OCHA said at least 40 civilians, including two children, were reportedly killed and nearly 200 injured between 19 October and the morning of the briefing, according to Ukrainian authorities. The World Health Organization has verified 557 attacks on healthcare this year, with 25 deaths and more than 230 injuries.

In the Democratic Republic of the Congo, nearly 12,000 people fled the Nambya area of Haut-Lomami on 19 October, joining some 14,500 displaced earlier in the month in Mitwaba, Haut-Katanga. In Haiti, the International Organization for Migration estimates more than 10,000 people have fled violence in Gros Morne, double an initial estimate of 5,000; partners have distributed 1,500 hot meals and hygiene kits since the start of the month.
