The current El Niño event is projected to cause 451,000 additional heat-related deaths globally between September 2026 and February 2027, according to a report by the Climate Impact Lab. This estimate is relative to average conditions during the same months from 1996 to 2025. The report, released on Wednesday, 23 September 2026, highlights that the toll is expected to be particularly high in the Global South.

India could experience approximately 15,800 additional heat-related deaths during this period, with nearly half of these fatalities anticipated between December and February. The report also projects significant death tolls in other regions: 66,800 in Africa's Sahel region, including 31,400 in Nigeria; 19,400 in Southeast Asia (Philippines, Vietnam, Thailand, and Cambodia); 19,300 in Indonesia; and 13,300 in Brazil.

Disagreement on specific figures

While the global figure of 451,000 additional deaths is consistently reported across multiple sources, one outlet, jurnalul.ro, states that 239,000 deaths could occur by the end of February 2027, with the total rising to 451,000 if previous months since June are included. The Climate Impact Lab's statement accompanying the report describes the current El Niño as a 'postcard from our future', bringing temperatures that climate change is projected to deliver in 20 years.

What the coverage left out

None of the left, centre, or right-rated reports mention the methodological limitations of the Climate Impact Lab's mortality estimate, which were detailed in The Hindu's full report. Specifically, the limitation that the report does not spell out the underlying numerical relationship or coefficients connecting a particular temperature increase to a number of deaths, with full methodological details to appear in a forthcoming peer-reviewed paper, was not mentioned in the digests or the full reports from Hindustan Times and Jyllands-Posten.

  • Reports from the left-rated outlets led with the global death toll and the projected impact of the El Niño event. The Hindu, which published the full report, noted that the current El Niño brings temperatures climate change is projected to deliver in 20 years, offering a glimpse of the future without adaptation investments. It also highlighted India's projected 15,800 additional heat-related deaths and the strain on coal-fired power plants due to increased electricity demand. IBTimes UK and Common Dreams highlighted the potential for 450,000 to 451,000 deaths, with IBTimes UK framing it as a 'Massive El Niño Threat Prompts Global Humanitarian Red Alert'. Al Jazeera noted that the heaviest toll is expected in poorer countries already struggling with food insecurity and high energy costs.

  • Centre-rated reports focused on the overall global and Indian death projections. Hindustan Times, which published the full report, stated that nearly half of India's projected deaths fall between December and February and that these fatalities are expected to keep rising into India's summer. It also mentioned that global land temperatures will be 1.2°C above normal in the coming months. Dailymail.com reported that scientists used climate models to predict the impact, while cedarnews.net issued a warning of over 450,000 premature deaths due to the El Nino-induced heatwave.

  • The single right-rated report from Jyllands-Posten focused on the forecast of heat during El Niño costing 450,000 lives in six months. The digest stated that the El Niño phenomenon is particularly strong this year and is leading to rising temperatures globally.

Questions about this coverage

How did the left and right cover El Niño heatwave could cause 451,000 deaths globally?
Of the 231 outlets on this story carrying a published leaning rating, 26% are rated left, 48% are rated centre, 26% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 459. The sections above set out what each side emphasised, in its own terms.
Is El Niño heatwave could cause 451,000 deaths globally left or right?
Neither side dominates it. Of the 231 rated outlets on this story, 26% are rated left, 48% are rated centre, 26% are rated right, and no side holds the 70% this site would want before calling a field one-sided. A story is not left or right in any case; the outlets that carried it are what carry ratings.
Is the coverage of El Niño heatwave could cause 451,000 deaths globally biased?
El Niño heatwave could cause 451,000 deaths globally is one event reported by 459 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
Which outlets covered El Niño heatwave could cause 451,000 deaths globally?
459 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.
How many additional deaths are projected globally due to the El Niño event?
The Climate Impact Lab projects 451,000 additional heat-related deaths globally between September 2026 and February 2027 due to the current El Niño event. This figure represents an increase compared to average conditions during the same period from 1996 to 2025.
What is the projected death toll for India?
India is estimated to experience approximately 15,800 additional heat-related deaths between September 2026 and February 2027. Nearly half of these projected fatalities are expected to occur during the months of December to February.
Which regions are projected to be most affected?
The Sahel region in Africa is projected to have the highest death toll with 66,800 additional deaths, followed by Nigeria with 31,400. Southeast Asia is expected to see 19,400 deaths, Indonesia 19,300, and Brazil 13,300.
What actions can be taken to mitigate these deaths?
The report suggests that decision-makers can take emergency actions to save tens of thousands of lives. These actions could include implementing heat warnings, providing health outreach to vulnerable populations, establishing cooling centres and hydration stations, ensuring worker protection, and expanding health system capacity.
