The UN weather agency has warned that the world is entering a climate 'danger zone' after confirming on Tuesday that El Niño conditions have returned in the Pacific Ocean, with sea surface temperatures in some tropical areas running about 6°C above average and raising the risk of a historic 'super El Niño' heat spike between June and November 2026.
The news came after months of mounting concern among climate scientists that the Pacific was primed for another powerful El Niño, barely two years after the 2023–24 event helped drive global temperatures to record highs. That episode was one of the five strongest on record and pushed heat, drought and flooding into what researchers openly described as 'uncharted territory.'
