India is likely to see about 55,000 additional heat-related deaths between October 2026 and March 2027, mostly in March, according to the University of Chicago’s Climate Impact Lab. The lab’s El Niño Heat Mortality Tracker projects a global toll of 857,000 by March 2027, with Nigeria and India facing the highest mortality over the next six months.

The projection is a sharp increase from the lab’s September 2026 estimate of 15,800 deaths for India, reflecting the addition of March to the forecast and observed temperatures for August and September that were significantly warmer than forecast. The lab warns such extreme heat could become commonplace within two decades.
Researchers said the tracker lets decision-makers identify high-risk regions and act before lives are lost. The tool provides state-level data worldwide.
Rediff and Down To Earth both report the same 55,000 death projection and 857,000 global toll from the University of Chicago’s Climate Impact Lab. Rediff leads with the headline figure and includes a death toll since June 2026 quoted from The Daily Mail, while Down To Earth provides fuller context: the sharp rise from the September 2026 estimate, the addition of March to the forecast, and the warning that such heat could become normal in 20 years. The coverage is substantially uniform straight reporting. The key open question, from the sources themselves, is whether the tracker’s state-level data will prompt pre-emptive action from policymakers and humanitarian organisations before March 2027.
