Cities are hotter than the surrounding countryside. Paved surfaces such as asphalt and concrete trap heat and release it at night. But as climate change worsens, this is becoming a real risk for residents.
Researchers are racing to find ways to protect urban residents from rising temperatures and pollution. As recent research shows, there’s no single fix for urban heat. Different places need different solutions, from tree canopies to cool roofs to reflective pavements.
