Around half were over the age of 60 and the hospital reports that heat likely played a role in many of the deaths. A lack of data in the countries affected makes it impossible to know how many people were killed, however it's likely there were hundreds or possibly thousands of other heat-related deaths.

Climate change, caused by burning fossil fuels like oil, coal and gas, and other human activities, is making heatwaves more frequent, longer and hotter around the world. To quantify the effect of human-caused warming on the extreme temperatures in the Sahel and West Africa, scientists analysed weather data and climate models to compare how these types of events have changed between today's climate, with approximately 1.

The scientists found that both the daytime and nighttime heatwaves, across both regions, would have been impossible if humans had not warmed the planet by burning fossil fuels like oil, coal and gas, and with other activities like deforestation. Climate change made the maximum temperatures 1.5°C hotter and the nighttime temperatures 2°C hotter for the Burkina Faso and Mali region, and the five-day daytime temperatures for the wider region 1.4°C hotter.

The study highlights factors that worsened the impacts of the heat across the region. The heat occurred at the end of Ramadan when many Muslim people fast during the day. The Sahel region has a large Muslim population and while high temperatures are common in April, the researchers say the relentless day and nighttime heat would have been overwhelming for many people who were abstaining from food and water.There was a problem processing your submission.
