The world could breach a new average temperature record in 2023 or 2024, fuelled by climate change and the anticipated return of the El Nino weather phenomenon, climate scientists say.
Climate models suggest that after three years of the La Nina weather pattern in the Pacific Ocean, which generally lowers global temperatures slightly, the world will experience a return to El Nino, the warmer counterpart, later this year.
During El Nino, winds blowing west along the equator slow down, and warm water is pushed east, creating warmer surface ocean temperatures.
“El Nino is normally associated with record breaking temperatures at the global level. Whether this will happen in 2023 or 2024 is not yet known, but it is, I think, more likely than not,” said Carlo Buontempo, director of the EU’s Copernicus Climate Change Service.
Climate models suggest a return to El Nino conditions in the late boreal summer, and the possibility of a strong El Nino developing towards the end of the year, Buontempo said. [Continue reading…]
