AI-generated summary
El Niño is a climate phenomenon that warms the waters of the equatorial Pacific Ocean, occurring every two to seven years.
El Nino, the climatic phenomenon that sees an anomalous warming of the waters of the equatorial Pacific Ocean, could prove this year to be one of the most powerful since 1950.
According to the UN meteorological agency (WMO), the phenomenon will intensify further before reaching its peak in December and will bring higher temperatures to much of the planet, adding to the effects of climate change. "It is likely - explains the agency - that it will bring above-average temperatures to much of the globe and change rainfall patterns, increasing the risk of drought and floods in several regions".
El Nino unfolds every two to seven years and lasts nine to twelve months. "Sea surface temperatures in the central and eastern tropical Pacific are expected to rise to record levels in the October-November-December quarter of 2026", with "repercussions on weather patterns and economies, ecosystems and communities around the world".
El Nino had made 2023 the second warmest year on record and 2024 the highest temperature year on record, coming in at about 1.55 C above the pre-industrial average of the 1850-1900 period.
