Super El Niño Could Cause 451,000 Excess Deaths, Researchers Warn
On 23 September 2026, Reuters and other outlets reported new research warning that the developing super El Niño is projected to cause roughly 451,000 excess deaths between winter 2026 and February 2027, primarily driven by extreme heat. The researchers emphasised that the event has already broken multiple historical temperature records before reaching its peak, with intensity and pace of development far exceeding any previous El Niño, posing a serious challenge to global public health and climate adaptation systems.
