The World Meteorological Organization (WMO) has issued a stark warning about the impending return of El Niño, which is likely to be one of the strongest in decades. With an 80% chance of developing before September and a 90% chance of persisting until November, El Niño is expected to exacerbate global warming and lead to extreme weather conditions worldwide. Experts predict that this phenomenon could result in unprecedented heat and flooding, particularly impacting regions like Britain, where temperatures may exceed 40°C. Professor Bill McGuire from University College London notes that the current heatwave is merely a precursor to more extreme conditions. UN Secretary General Antonio Guterres has called for urgent action, stating that El Niño will intensify the effects of climate change, causing widespread and severe impacts. The last El Niño was recorded in 2023-24 and was among the five strongest summers, with this summer potentially breaking those records. The current warming trends in the Pacific Ocean are fueling these conditions, which could lead to significant climate disruptions across the globe.
