 African cities are experiencing an increase in nighttime heatwaves due to urbanization, which leads to higher temperatures and longer durations of heatwaves. Urbanization also increases the risk of heatwaves in arid regions by reducing wind speed and evaporation. To mitigate these risks, adaptation measures should focus on reducing heatwave exposure in urban areas. This article was authored by EGOSA AIGUN, Chienshu, Zitongshu, and others.
