Super El Nino: Scientists warn about potential of upcoming event
Scientists warn a potentially 'super' El Niño could develop in the Pacific by July, with sea temperatures possibly surging 2.5C above average, though its strength remains uncertain due to unpredictable wind patterns. The US NOAA estimates an 80% chance of El Niño forming, with experts like Adam Scaife of the UK Met Office suggesting it may rival the strongest events in decades, potentially driving record global temperatures in 2026 or 2027.
A potentially extreme El Niño event is forming in the tropical Pacific, with forecasters warning its intensity remains uncertain. The US National Oceanic and Atmospheric Administration (NOAA) reports an 80% chance of El Niño developing by July, as sea temperatures in key equatorial zones rise rapidly. Several weather services predict temperatures could exceed 2.5C above average, matching only three prior events since 1877. Scientists emphasize that El Niño’s strength depends on volatile atmospheric interactions, particularly trade winds. While NOAA forecasts a 33% chance of a 'super El Niño' (2C or higher), unpredictable wind shifts could stall or reverse its development. Michelle L’Heureux, NOAA’s El Niño lead, notes these winds are difficult to predict months in advance. El Niño typically peaks in December but lingers, influencing global temperatures for years. Past events, including 1997/98 and 2015/16, drove record heat, with experts warning 2027 could break global warmth records if this event intensifies. Adam Scaife of the UK Met Office calls it a ‘big event,’ though climate change’s role in amplifying El Niño remains unclear. Even a weaker El Niño could worsen extreme weather, as rising ocean and atmospheric heat may heighten its impacts. Scientists stress that while stronger events increase risks, outcomes vary—yet the backdrop of climate change could exacerbate effects regardless of intensity.
