The Critical Role Trees Play During Heat Waves

Summary

Carlos Claussell Velez discusses the significant impact of trees in mitigating the effects of urban heat islands, particularly during heat waves. Urban areas with fewer trees experience higher temperatures, contributing to health risks and energy costs. This disparity often affects marginalized communities more severely, exacerbating existing inequities. Trees help cool the air through shade and evapotranspiration, which can reduce temperatures by 12-18°F. Initiatives like Philadelphia’s Beat the Heat campaign and the Philly Tree Plan aim to increase tree cover in underserved areas. Velez advocates for nature-based urban planning solutions, community involvement, and extending protections to outdoor workers to build more resilient and equitable cities.
