UN Warns of 'Supersized' El Niño, Expects Extreme Heat and Disruptive Weather Globally Through Early 2027

The UN and World Meteorological Organization (WMO) have issued an unequivocal forecast that the El Niño climate pattern is rapidly intensifying and is almost certain to persist through February 2027. This 'supersized' El Niño is expected to bring months of extreme heat, floods, drought, and disruptive weather worldwide, with the WMO undertaking a major mobilization to strengthen forecasts and early-warning systems. UN Secretary-General António Guterres stated the planet is in 'uncharted waters' due to the phenomenon, which is amplified by human-induced climate change.
