The United Nations is issuing urgent warnings about an exceptionally powerful El Niño phenomenon unfolding with unprecedented intensity. Officials describe the climate event as "supersized" and warn the world is entering a "danger zone" characterised by extreme and volatile weather patterns that will demand global preparation and response.

Meteorological authorities have issued their most confident forecast on record, projecting with near-certain confidence that this El Niño episode will sustain its strength through early 2027. The event is tracking to become the strongest El Niño cycle ever observed, with scientists and policymakers preparing populations and infrastructure for widespread disruption to weather systems, agriculture, and water resources across multiple regions.
