More than 450,000 people are projected to die from the additional heat brought by the super El Niño by February, according to estimates by climate scientists.
uncertain
people → project → scientists
The toll is on top of the early deaths resulting from temperatures already driven up by the climate crisis.
asserted
toll → result → crisis
It will strike across the globe, from Indonesia to India, and Nigeria to the United States.
asserted
It → strike → States
Many further deaths are expected from the droughts, wildfires, and flooding that El Niños bring.
asserted
Niños → expect → that
The heat deaths have been estimated at regional level, and the researchers said the projections therefore identified where measures to protect people could be put in place and save lives.
uncertain
measures → estimate → lives
Such actions could include better heat forecasts, cooling centers where people can shelter, increased staffing for medical facilities at the hottest times and protections for outdoor workers.
uncertain
people → include → workers
The El Niño currently heating up the planet burst through the highest temperature ever recorded for the phenomenon on Monday, several months before its expected peak.
asserted
Niño → heat → peak
The heat is so much greater than previous events that scientists have called it “mind-blowing” and “Godzilla-level.”
asserted
scientists → call → it
El Niños are natural climate events but may be made worse by global heating.
uncertain
Niños → make → heating
“The estimate of 451,000 people is such a large number that it can be numbing, but it is made up of parents and children, grandparents and neighbours, people going to work, caring for families, and living their lives,” said Michael Greenstone, co-founder of the Climate Impact Lab and a professor at the University of Chicago, who co-authored the report.
asserted
who → numb → report
The estimate of deaths is for the period June 2026—as some heat deaths will have already occurred—to February 2027, which is when current temperature forecasts end.
asserted
forecasts → occur → February
But elevated levels of heat deaths are expected to continue until June or July 2027.
asserted
levels → expect → June
The most affected countries in the next six months are the tropical nations of Nigeria, Indonesia, Sudan, India, and Brazil.
asserted
countries → affect → Nigeria
The US is in the top 20 most affected nations, with 3,500 projected additional heat deaths.
asserted
US → affect → deaths
The El Niño is also a “postcard from our future,” the researchers said, pushing up temperatures to the level the climate crisis is projected to deliver in 20 years.
asserted
crisis → say → years
“Increasing emergency response and better targeting our efforts can save many lives this year,” said report co-author Tamma Carleton at the University of California, Berkeley.
asserted
Carleton → increase → California
“But 20 years from now, once today’s extreme temperatures become the new normal, we don’t want to be in a constant state of emergency…
asserted
we → become → emergency
We need to mobilize now to design, deploy, and evaluate the tools that will save lives in the years ahead.
asserted
that → need → years
The projections were made using peer-reviewed methods that track the month-by-month relationship between temperature and additional heat deaths in 24,378 regions across the world.
asserted
that → make → world
This was combined with the forecasts for higher temperatures due to El Niño in the months ahead.
asserted
This → combine → months
“People have been able to forecast when there’s going to be shocks to crops, and give advance warning of that,” said Greenstone.
asserted
Greenstone → forecast → that
“This new report is opening the door to being able to do it for an even more important outcome—I would say the most important outcome—which is death.”
asserted
which → open → outcome
The report will be submitted to a peer-reviewed journal, but Greenstone said that, given the urgency of the situation, “it would have been irresponsible to sit on it.”
asserted
it → submit → it
Food supplies will also be hit by El Niño, with the World Food Programme warning in August that its impacts were likely to push about 50 million people into acute hunger and drive prices up.
asserted
impacts → hit → prices
A major El Niño in 1877-1878 led to more than 50 million deaths due to drought and famine, with India, Brazil, and China severely affected.
asserted
India → lead → drought
Friederike Otto, a professor at Imperial College London, told The Guardian on Monday: “The [current El Niño] event is a huge redistribution of energy in the climate system and is dangerous, because it is unfolding on top of a much warmer, human-influenced climate system.”
asserted
it → tell → system
“So, he continued, “in many places around the world we will see never-before-experienced heat extremes, with all their consequences on health, food security and water stress.
asserted
we → continue → health
El Niño comes and goes, but as long as we continue to burn fossil fuels, it occurs on an increasingly hotter baseline, making it much more difficult for communities to deal with the consequences.”

communities → come → consequences
