Climate scientists predict that the world could reach a new average temperature record in 2023 or 2024 due to climate change and the anticipated return of El Nino weather phenomenon. After three years of the La Nina weather pattern, which tends to lower global temperatures, climate models suggest a return to the warmer El Nino later this year. During El Nino, warm water is pushed east from the Pacific Ocean, creating warmer surface ocean temperatures. Carlo Buontempo, director of the EU’s Copernicus Climate Change Service, said that El Nino is commonly linked to record-breaking temperatures at a global level. From 2016, the world’s hottest year on record, climate change has fuelled extreme temperatures, even in years without the El Nino phenomenon. The world’s average global temperature has risen by 1.2C since pre-industrial times, despite major emitters pledging to reduce their net emissions to zero. Friederike Otto, a senior lecturer at Imperial College London, said El Nino-fueled temperatures could worsen climate change impacts such as severe heatwaves, droughts, and wildfires.
