Street green space can help cool cities, but it will not be enough on its own

Phys · · 784 words · By International Institute

A study led by IIASA finds that while expanding street green space can reduce urban heat stress, it is insufficient on its own and must be combined with other adaptation measures. The research highlights regional and climatic variations in cooling effectiveness and emphasizes the need for integrated urban planning to address rising temperatures.
