Very strong El Niño years are linked to a +28.87% rise in global heat-related mortality (+107,035 annual deaths; 95% eCI: 27,336 to 176,312).
- Why it matters: ENSO is known to shape climate via atmospheric connections, but its quantified contribution to the global and regional temperature-mortality burden is still unclear.
- What they did: The study combined global temperature and mortality databases with epidemiological models to estimate temperature-related mortality tied to ENSO variability and intensity.
- The result: Heat-related mortality increases were concentrated in low and medium HDI countries (67.65% of the global increase), implying upcoming El Niño events may create new public health challenges.
