Extreme Heat in Phoenix, Sacramento, and Portland

This summer, the Arizona Burn Center has reported 65 admissions for severe heat-related burns, a stark contrast to the 645 heat-related deaths recorded in Maricopa County last year. Dr. Kevin Foster, the center’s director, emphasizes the urgent need for cities to address the multifaceted challenges posed by extreme heat. In response, Phoenix is implementing strategies such as increasing tree planting and enhancing shade to protect its residents. The city’s “Cool Pavement” initiative has treated 120 miles of asphalt to reflect sunlight and reduce surface temperatures. In California, Sacramento, known as the City of Trees, faces its own challenges, particularly in low-income neighborhoods where residents experience a lack of shade and green spaces during heat waves. Victoria Vasquez, grants and public policy manager for California ReLeaf, highlights the importance of urban forestry in mitigating heat impacts. The coalition aims to address these disparities and promote the growth of urban forests to enhance community resilience against extreme temperatures. Meanwhile, Portland, Oregon, has also felt the effects of rising temperatures. The city’s tree-rich areas, such as Forest Park, provided relief during last week’s heat wave. However, the Multnomah County medical examiner's office is investigating five deaths potentially linked to the extreme heat. Dr. Shandas notes that since the devastating heat dome of 2021, Portland has become more aware of heat threats, yet he expresses concern over the city’s preparedness for future heat waves, calling for a comprehensive long-term strategy.
