A Climate Impact Lab report says El Niño weather-related mortality is likely to kill 15,800 people in India by the end of February. The same report warns that the heaviest toll will fall in places that are already hot and relatively poor, where people in India face the sharpest heat risk.
The estimate is not a broad annual forecast. It is a near-term projection tied to El Niño, a natural climate pattern that returns every two to seven years toward the end of the year. Climate Impact Lab said the pattern can drive unusually dangerous heat, and it projected as many as 451,000 more deaths between June and February of next year compared with typical heat-related deaths in a year.
The report also points to how hot the Pacific already was before the latest warning. In July this year, NOAA was observing temperature increases of greater than 3 degrees Celsius in the eastern and central Pacific, while El Niño patterns are considered strong if the surface temperature of the water off the west coast of South America is over 1.5 degrees Celsius above average. That measurement is one of the reasons the report treats the current episode as a serious mortality risk for India and the Global South.
India and Climate Impact Lab
The report said the largest heat burden will fall on people in India who live in already warm and relatively poor places. Climate Impact Lab framed that risk around death counts, not just higher temperatures, and the headline figure for India by the end of February is 15,800 deaths.
For readers in India, the practical meaning is direct: the danger is concentrated where heat is already part of daily life and where fewer resources can soften exposure. The estimate also suggests that the current El Niño cycle is being tracked not only as a climate event, but as a public-health threat with a short fuse.
Mark Carney and New Delhi
The same set of facts also carries a separate diplomatic thread. Mark Carney said India had confirmed that Prime Minister Narendra Modi would visit Canada in December 2026 around the G20 meet in the United States, and he made the remarks on the sidelines of the United Nations General Assembly in New York on Tuesday. Carney said, “We are making good progress in our trade negotiations with India. It is an exceptionally important relationship on many, many levels, people-to-people levels, security levels, and also trade and economic,” before adding, “I believe that India just confirmed that the prime minister will be visiting Canada around that time. The precise date isn't out, but I very much look forward to hosting him,”
New Delhi has not yet publicly confirmed the trip. Modi last visited Canada to attend the G7 summit in June 2025, after India-Canada relations hit the pit in 2023 over sharp disagreements on Sikh separatism. The gap between Carney’s remarks and New Delhi’s public position is the immediate diplomatic friction in the story.
Canada, the G20 meet
The next confirmed point in the Canada thread is the planned December 2026 window around the G20 meet in the United States. Until New Delhi publicly states its position, Carney’s comments stand as his account of the trip, while India’s public silence leaves the travel plan short of full diplomatic closure.
On the climate side, the next practical question is how Climate Impact Lab calculated the India estimate from heat exposure, population vulnerability, and the strength of the El Niño pattern. For people in India, the number that matters most today is still 15,800, because it puts a near-term death toll on a weather event that is already under way.
