The University of Arizona’s Southwest Center on Resilience for Climate Change and Health (SCORCH) and Arizona Institute for Resilience (AIR) joined the City of Tucson, Pima County, and other community members, leaders, and experts for a daylong workshop to address extreme heat in southern Arizona communities. The event, hosted at the University of Arizona’s Environment & Natural Resources (ENR2) building, included a series of presentations via plenary sessions and smaller breakout groups throughout the day with topics focused on heat preparedness in southern Arizona communities. Breakout sessions explored the built environment (resilience hubs), energy and the grid, public health and healthcare, community and neighborhood level action, and workforce and heat protection.
