Researchers at the Climate Impact Lab, based at the University of Chicago, released a stark forecast on Wednesday: the powerful El Nino event expected to run from June 2026 through February 2027 could generate as many as 451,000 additional heat‑related deaths worldwide compared with a typical year.
Who will be hardest hit
The study projects the greatest toll will fall on the Global South – nations already grappling with food insecurity, high energy costs and limited health infrastructure. The Sahel region of Africa tops the list, with an estimated 66,800 extra deaths. South and Southeast Asia also face severe risk, with roughly 19,400 additional deaths across the Philippines, Vietnam, Thailand and Cambodia, 19,300 in Indonesia, 15,800 in India, and 13,300 in Brazil.
Why the heat matters
Co‑author Michael Greenstone explained that heat is most lethal in places that are already hot and relatively poor. “If you’re already in a hot place, the extra couple of degrees are going to be much more dangerous,” he said. Wealthier regions tend to have broader access to air‑conditioning, reliable water supplies and robust health systems, which can blunt the impact.
The researchers arrived at their figures by pairing seasonal temperature forecasts with localized mortality models covering more than 24,000 regions worldwide. They compared projected deaths under El Nino‑driven temperatures with a baseline that assumes temperatures remain similar to the average of the past three decades.
Policy recommendations
While the numbers are alarming, the report also outlines concrete steps governments can take to mitigate loss of life. Recommended actions include:
- Establishing heat‑warning systems that alert communities ahead of extreme temperature spikes.
- Setting up cooling centers and hydration stations, especially in neighborhoods with limited air‑conditioning.
- Providing protections for outdoor workers, such as mandated breaks and shade.
- Expanding hospital capacity and ensuring rapid access to medical care for vulnerable populations, including the elderly.
- Targeted outreach to at‑risk groups to educate them on heat‑safety practices.
The authors also call for “anticipatory financing,” urging governments to allocate resources before the heat peaks so that emergency measures can be deployed without delay.
Expert reaction
Abhiyant Tiwari, a heat‑expert with NRDC India who was not involved in the study, said the projections should spur action rather than panic. “The real measure of our preparedness is not how many heat warnings we issue, but how effectively we protect people and reduce preventable deaths,” he noted.
India, for example, already runs a national heat‑action plan that includes early warnings and public‑health messaging. Yet Tiwari cautioned that implementation and funding remain challenges for many developing nations.
El Nino in the context of climate change
El Nino is a natural climate pattern, but this year’s unusually strong event is unfolding on a planet already warmed by human‑caused climate change. The Climate Impact Lab estimates global land temperatures during this El Nino could be about 1.2 °C (2.1 °F) higher than normal, creating roughly 44 % more extremely hot days than in a typical year.
Those conditions, the researchers say, may mirror what the world could regularly experience in about twenty years if greenhouse‑gas emissions continue on their current trajectory. In that sense, the current El Nino offers a preview of future climate risks and an urgent call for decision‑makers to act now.
What communities can do
Local leaders, faith groups, and families are encouraged to take the study’s recommendations to heart. By establishing neighborhood cooling hubs, checking on elderly relatives, and supporting policies that expand access to reliable water and electricity, communities can help shield their most vulnerable members from the looming heat threat.
As the El Nino season progresses, the emphasis remains on preparedness, not fear. With coordinated effort, the projected death toll can be reduced, saving tens of thousands of lives across the globe.
