Cities are significantly hotter than their surrounding areas. That difference, known as the “urban heat island” effect, is driven in significant part by the dark-colored buildings, sidewalks, roadways, and similar surfaces that dominate urban spaces, absorbing solar energy and later radiating it outward as thermal energy that heats the nearby air. This article suggests and describes one avenue through which cities and local community-based organizations could tackle extreme heat: partnering with one another to transform paved surfaces into green or reflective ones. Partnerships of this kind could combine the resources and desire to create green spaces that nongovernmental groups offer with cities’ large portfolios of property.
