Concrete and asphalt roads, and other built materials readily absorb, store and release heat, raising city temperatures, a phenomenon called the urban heat island. (Pixabay)

Small green spaces can help keep cities cool during heat waves

During heatwaves, the highest temperatures are often found in urbanized areas. Small green spaces are often overlooked as a way to cool urban areas.
