New study predicts a super‑El Niño could cause over 450,000 heat‑related deaths by February, highlighting significant health risks for vulnerable populations.
A new study warns the current super‑El Niño could cause more than 450,000 heat‑related deaths worldwide by February.
Why the forecast matters
The researchers used climate‑model simulations and historical mortality data to estimate excess deaths linked to extreme heat. They said the combination of higher temperatures and prolonged dry spells amplifies health risks, especially for vulnerable populations.
Regional impacts
India features prominently in the analysis. The study projects roughly 15,800 heat‑related fatalities in the country by the end of February if the event persists. Other regions, including parts of Africa and the southern United States, also face heightened mortality, though the study did not publish exact figures for those areas.
In addition to human health, the researchers highlighted agricultural losses, water‑stress emergencies, and increased energy demand for cooling. They said these secondary effects could exacerbate the death toll by straining public services.
Calls for immediate action
Public‑health officials urged governments to activate heat‑alert systems, expand cooling shelters, and prioritize medical resources for at‑risk groups. Climate scientists emphasized that the super‑El Niño is a natural phenomenon intensified by long‑term warming, and that mitigation of greenhouse‑gas emissions remains essential to reduce future extreme‑event frequency.
While the study’s authors cautioned that projections carry uncertainty, they said the scale of potential loss warrants urgent preparedness measures. They also called for more granular data collection to refine mortality estimates as the event evolves.
Policy makers in affected nations have begun reviewing emergency response plans. Observers noted that coordinated regional action could limit the projected death count and alleviate secondary hardships.
