Researchers at the Climate Impact Lab of the University of Chicago have issued a warning that the current super El Niño event may lead to a significant increase in deaths worldwide. According to their report, the extreme heat caused by this phenomenon could result in up to 451,000 additional deaths globally over the next six months, ending in February 2027. This projection is based on an expected 44% rise in extremely hot days compared to an average year.
The countries anticipated to be most severely affected by the heat-related deaths are Nigeria, Indonesia, and Sudan. Nigeria is projected to experience around 31,400 additional deaths, followed by Indonesia with approximately 19,300 deaths, and Sudan with about 17,600 deaths. The Sahel region in Africa, which includes Niger, Chad, Nigeria, and Sudan, is expected to account for 66,800 additional deaths during the six-month period.
Other regions predicted to face significant heat-related mortality include the Philippines, Vietnam, Thailand, and Cambodia, which together may see around 19,400 additional deaths. The researchers emphasize that if the El Niño event extends into 2027, the number of excess deaths could be even higher, particularly in the Northern Hemisphere, including countries such as India and Pakistan, which are expected to be at high risk during the summer months.
The Climate Impact Lab describes the current El Niño event as a "message from the future," indicating the rising temperatures that will become the norm in a few decades. The researchers stress that emergency response efforts should be directed towards areas of high priority to minimize heat-related deaths in the coming months.
According to Michael Greenstone, an economist at the University of Chicago, this report enables policymakers to identify areas where emergency actions can be taken now to save tens of thousands of lives in the coming months. The researchers' findings highlight the urgent need for targeted interventions to mitigate the impact of extreme heat on vulnerable populations.
The World Meteorological Organization (WMO) has also emphasized the importance of enhancing preparedness to cope with heat in cities. As the global community faces the challenges posed by climate change, the need for proactive measures to protect public health has become increasingly pressing.
The study's findings serve as a call to action for governments and health organizations to develop and implement effective strategies for addressing the health impacts of extreme weather events. By prioritizing the most vulnerable regions and populations, it may be possible to reduce the number of heat-related deaths and prevent unnecessary suffering.
Key points
- Up to 451,000 additional deaths may occur globally due to the super El Niño event by February 2027.
- Nigeria, Indonesia, and Sudan are expected to be among the countries most severely affected by heat-related deaths.
- Emergency response efforts should be directed towards areas of high priority to minimize heat-related deaths in the coming months.
