The impacts of the Urban Heat Island (UHI) are ubiquitous in our hot city and in urban areas across the globe, adding upwards of 22 degrees F to the daytime temperature. Worse, UHI also increases nighttime temperatures, which in Tucson are the saving grace of our triple-digit summer days. In his in-depth presentation “Planning for Extreme Heat,” Dr. Ladd Keith of the University of Arizona’s School of Architecture — whose primary research focus is the intersection between climate change and urban planning — presents the problems and the solutions. He also cautions that very little has been done to address UHI, particularly where solutions are most needed: in our disadvantaged neighborhoods.
