Researchers at the University of Chicago's Climate Impact Lab have warned that extreme heat linked to this year's "super-El Niño" could cause up to 451,000 additional deaths worldwide in the six months to February 2027. The report stated that the number of extremely hot days could rise by 44 percent compared with normal years. This projection has raised concerns about the potential impact on global health.
The Climate Impact Lab described the current El Niño as a "postcard from the future", saying the extreme temperatures being seen now could become normal within a few decades. The researchers emphasized that emergency measures should focus on regions most at risk from extreme heat and related deaths. This warning comes as several countries, particularly in Africa and Asia, prepare for the potential consequences of the super-El Niño event.
Nigeria is expected to record the highest number of additional heat-related deaths, at about 31,400. Indonesia could see 19,300 deaths, while Sudan could record 17,600. Across Africa's Sahel region, including Niger, Chad, Nigeria, and Sudan, extreme heat could cause an additional 66,800 deaths during the six-month period. These numbers highlight the urgent need for preventive measures and healthcare preparedness in these regions.
The Philippines, Vietnam, Thailand, and Cambodia are also expected to face a combined 19,400 additional deaths. The death toll could rise further if El Niño continues into 2027. Researchers warned that parts of the northern hemisphere, particularly India and Pakistan, could face greater risks during their summer months. This has significant implications for global health security and the need for coordinated responses.
Michael Greenstone, an economist at the University of Chicago and co-founder of the lab, said the findings could help authorities identify where urgent action is needed. He emphasized that the report could help decision-makers take steps to save tens of thousands of lives in the coming months. The research aims to inform policy and emergency response strategies to mitigate the impact of extreme heat.
The super-El Niño event has far-reaching implications for global health, with the potential to overwhelm healthcare systems and exacerbate existing health challenges. The Climate Impact Lab's research underscores the need for proactive measures to address the health risks associated with extreme heat. By understanding the potential consequences, governments and health organizations can develop targeted interventions to reduce the impact.
As the situation continues to unfold, it is essential for governments, healthcare providers, and communities to work together to prepare for the potential consequences of the super-El Niño event. By taking proactive steps to address the health risks associated with extreme heat, it may be possible to reduce the number of deaths and mitigate the impact on vulnerable populations.
Key points
- Up to 451,000 additional deaths worldwide are predicted in the six months to February 2027 due to extreme heat linked to this year's "super-El Niño".
- Nigeria, Indonesia, and Sudan are expected to be among the countries most affected by the extreme heat, with significant numbers of additional heat-related deaths predicted.
- The research aims to inform policy and emergency response strategies to mitigate the impact of extreme heat and save tens of thousands of lives in the coming months.
