UN warns El Niño could make 2027 warmest year on record, escalating climate crisis

The UN's World Meteorological Organization released a report predicting that an El Niño event expected by late 2026 will increase the likelihood of 2027 becoming the warmest year on record, according to lead author Leon Hermanson. The WMO analysis argues the climate crisis could intensify significantly over the next five years, with record-breaking temperatures posing risks to global agriculture, water supplies, and public health. This forecast matters globally because it shapes international climate policy and corporate adaptation planning ahead of critical emissions reduction deadlines. The report comes as Europe and other regions already experience severe heat waves.
