The World Meteorological Organisation (WMO) warns that an unusually strong El Niño could push global temperatures even higher, raising the likelihood that 2027 becomes the hottest year on record. The assessment links the expected climate pattern with the ongoing warming trend caused by greenhouse gas emissions, suggesting the impacts of El Niño would be added to long-term background warming.
Both reports say WMO’s concern goes beyond temperature, pointing to the potential for more intense weather extremes. One outlet highlights the risk of heatwaves and other high-temperature events, as well as shifts in rainfall patterns that could bring stronger extremes. The other focuses on the timing and likelihood of record warmth by linking El Niño strength with the longer-term effects of climate change, as discussed in the lead-up to or context of COP31.
