Nigeria Faces Potential for 31,400 Heat-Related Deaths by Early 2027, Report Warns

Nigeria may see an alarming rise in heat-related deaths, with a report predicting 31,400 additional fatalities between September 2026 and February 2027. This projection comes as the El Niño weather pattern intensifies, which is expected to cause extreme temperatures across the region.

The Climate Impact Lab published the report on September 22, 2026, stating that Nigeria is among the countries likely to experience the highest number of heat-related deaths globally. The report estimates that nearly half of the 66,800 expected deaths across the Sahel region will occur in Nigeria.

Globally, the report anticipates 451,000 additional heat-related deaths during the same period compared to an average year. Researchers expect land temperatures to rise by 1.2 degrees Celsius, leading to 44% more extremely hot days than usual.

Michael Greenstone, a co-founder of the Climate Impact Lab, emphasized the human cost of these projections, noting that they represent real people in everyday situations. He highlighted the importance of understanding the impact of rising temperatures not just on crops but on human lives.

The report suggests that the extreme heat expected during this El Niño event could become a regular occurrence in the future due to climate change. It describes the current situation as a “postcard from the future,” warning that what seems unusual now may become the norm in the coming decades.

To mitigate the expected toll, the report calls for urgent action from governments and humanitarian organizations. Suggested measures include heat warnings, health outreach, cooling centers, hydration stations, and increased healthcare capacity. The report stresses the importance of preparing for both immediate and long-term challenges posed by rising temperatures.

Tamma Carleton, a co-author of the report, noted that while emergency responses are crucial, long-term planning is equally important. She urged for mobilization of resources to develop tools that can save lives in the future.
