Urban overheating is becoming a recurring phenomenon, resulting from the cumulative effect of climate change and the Urban Heat Island (UHI) phenomenon. Climate change is leading to an increase in the intensity and duration of heat waves (hot air masses causing high temperatures for several consecutive days) in different parts of the world. These meteorological phenomena themselves reinforce the UHI, a climatic effect causing a difference in temperature between the centre of urban areas and outlying or natural areas, which can be greater than 10 °C during heat waves. The effect is even more pronounced at night, when the heat stored by artificialised land and buildings is released into the air, keeping the temperature high. Faced with the various consequences (social, environmental, economic) and climate projections, local and regional authorities are now faced with the need to adapt their cities in order to combat this phenomenon. Below is an overview of the challenges and solutions.
