The City of Philadelphia’s Office of Sustainability (OOS) has identified increased precipitation/flooding and increased heat as the main dangers of climate change to Philadelphia with underserved neighborhoods of color being particularly at risk for the worst effects. Extreme heat is being tackled by many organizations at multiple levels, with cities being of special concern. Cites are temperature hotspots that house large (and often increasing) densities of people. This project is led by Russell Composto, Associate Dean for Undergraduate Education and Professor at Penn Engineering, and Kristin Field, Director of Education and Professional Development for an NSF Research Traineeship project and the Singh Center for Nanotechnology. Together with the leadership of the Penn Institute for Urban Research (Co-Directors and Professors Eugenie Birch and Susan Wachter and Managing Director Amy Montgomery), they seek to deepen connections with OOS to determine whether Penn’s faculty and students could contribute to the immediate and longer-term City plans for adaptation to extreme heat events. This community of experts focusing on Philadelphia will address an urgent need in our local community…one with undeniable global relevance.
