UN Warns of Imminent El Niño Return and Escalating Weather Extremes
The United Nations, backed by the World Meteorological Organization, says there is an 80% chance El…
Executive Summary: A Climate Alarm Bell RingsThe UN has issued a stark warning that El Niño is likely to re‑emerge this year, bringing a wave of super‑charged weather extremes. With an 80% probability of formation before September and a 90% chance of lasting until November, the pattern threatens to amplify global warming, disrupt food supplies and intensify floods and droughts.UN and WMO Forecast an Imminent El Niño DevelopmentThe World Meteorological Organization (WMO) released its latest outlook on Tuesday, noting that most climate models project the return of the cyclical phenomenon at “at least moderate” strength, with some indicating a potentially strong event. Scientists caution it could become the strongest El Niño of the 21st century.Formation window: before September 2026Persistence window: through November 2026Strength: moderate to strong, possibly the strongest this centuryKey Numbers: Probabilities, Temperatures and Regional ImpactsThe WMO’s quantitative outlook highlights:80% chance of El Niño onset before September90% chance it will continue into NovemberUnusually high temperatures forecast for nearly all regions over the next three monthsIncreased likelihood of extreme rain in South America, the southern US, the Horn of Africa and Central AsiaDrier conditions expected in Central America, the Caribbean, Australia, Indonesia and parts of South AsiaWhy This Matters: Global Climate, Food Security and Economic RisksEl Niño acts as a “fuel‑on‑the‑fire” for a warming planet, according to António Guterres, UN Secretary‑General. The pattern can:Push global temperatures higher, contributing to record‑breaking heat years (2024 already set new highs)Exacerbate droughts that strain water supplies and agricultural yieldsTrigger severe flooding and landslides, as seen in Tanzania’s April 2024 rainsInfluence hurricane formation—enhancing storms in the central/eastern Pacific while suppressing them in the AtlanticExperts like Gareth Redmond‑King of the Energy & Climate Intelligence Unit warn that the looming El Niño could jeopardise already fragile food systems, especially as fertilizer supplies are constrained by geopolitical conflicts.Looking Ahead: 2027 and the Next Decade of Climate RiskThe UN stresses that the most severe impacts may materialise in 2027, when El Niño could drive the hottest year on record. Preparing now means:Accelerating the transition away from fossil fuelsScaling renewable‑energy deploymentStrengthening early‑warning systems for vulnerable communitiesImplementing climate‑resilient agricultural practicesFailure to act could lock in a trajectory of escalating heat, water scarcity and food insecurity for the coming decade.
