India could face more than 55,200 additional heat-related deaths between October 2026 and March 2027 if projections linked to an anticipated extreme El Niño event materialise, according to figures attributed to the Climate Impact Lab. The warning places India among the countries expected to bear the heaviest human cost of rising temperatures, alongside Nigeria and Brazil.
The projections, cited in the reported El Niño Heat Mortality Tracker, point to the potential consequences of extreme heat across several regions. However, the estimates are forecasts rather than confirmed deaths, and the scale of the impact will depend on how weather conditions develop and how effectively governments prepare for prolonged heat.
Global Heat Death Toll Could Exceed 373,000 In Six Months
The Climate Impact Lab’s latest tracker estimates that approximately 373,000 additional heat-related deaths could occur worldwide between October 2026 and March 2027. The projected toll rises to about 857,000 for the period from June 2026 through March 2027, including deaths estimated for months that have already passed.
These figures represent estimated deaths above a historical baseline, not a confirmed count of fatalities directly attributed to El Niño. The tracker combines observed temperature data with seasonal forecasts to estimate the potential impact of extreme heat.
India Among Countries Facing Highest Heat Risks
The tracker’s projections for October 2026 to March 2027 identify the following countries as facing some of the highest additional heat-related mortality risks:
- Nigeria: Approximately 56,000 deaths.
- India: Approximately 55,000 deaths, with a substantial share projected for March.
- Indonesia: Approximately 29,000 deaths.
- Brazil: Approximately 19,000 deaths.
- Sudan: Around 14,700 deaths, according to the figures cited in the report.
For India, the projections raise concerns about the approaching summer, particularly for outdoor workers, older people and communities with limited access to cooling facilities and healthcare.
The estimates also highlight the importance of heat-action plans, early-warning systems, drinking-water access and adequate medical facilities to protect vulnerable populations.
Pacific Ocean Warming Raises Concern
El Niño is a natural climate pattern involving warmer-than-average sea surface temperatures in the central and eastern equatorial Pacific. It can alter rainfall and temperature patterns across the world, increasing the likelihood of certain extreme weather events.
The World Meteorological Organisation (WMO) reported that sea surface temperature anomalies in the Niño 3.4 region had risen sharply during 2026. Its October–December forecast projected an anomaly of around 3.7°C above normal, potentially exceeding the previous record.
The term “Super El Niño” is commonly used to describe an exceptionally intense event, but the WMO does not use it as an official classification. The organisation classifies El Niño events by their intensity and warns that their impacts vary by region and by how the event interacts with other climate patterns.
Heat, Drought And Disrupted Rainfall Add To The Risks
El Niño can shift rainfall patterns, contributing to drought in some regions and heavier rainfall in others. The consequences can extend beyond heat-related illness, affecting water supplies, agriculture, food security and livelihoods.
In India, the concern includes the possibility of disrupted monsoon rainfall and the risk of intense heat as summer approaches. The actual effects will depend on the event’s development and its interaction with other climate conditions.
Researchers Call For Early Action To Save Lives
Michael Greenstone, co-founder of the Climate Impact Lab and a professor at the University of Chicago, said the ability to anticipate the deadly effects of extreme heat gives policymakers an opportunity to act before lives are lost.
The tracker is designed to help governments and organisations identify high-risk regions and direct resources towards measures such as early-warning systems, expanded healthcare access and cooling centres. Climate Impact Lab
The projections are a warning about the potential human cost of extreme heat, not a certainty about future deaths. Preparedness, access to essential services and timely public-health interventions could help reduce the toll as the El Niño event develops.
