Cities are using nature to cut urban temperatures – by 2°C in one case

Cities around the world such as Medelin (Columbia), Singapore, and Dusseldorf (Germany) are integrating nature into their infrastructure and built environments to reduce urban heat island effects, increase biodiversity, and improve air quality. In a time of global warming, these nature-based retrofits to impervious roadways and rooftops with trees, shrubs, and other plantings are effectively lowering temperatures by promoting shade, evapotranspiration, and reduced black top asphalt.
