Extreme heat is the deadliest weather hazard in the U.S., posing significant risks to public health, infrastructure, and ecosystems. Urban heat islands, particularly in Massachusetts' industrial cities, exacerbate these challenges, disproportionately affecting working-class neighborhoods. Prolonged heat exposure can lead to health issues, reduced educational outcomes in schools without air conditioning, and stress on infrastructure like railways and water supplies. Vulnerable populations, including children and the elderly, are at heightened risk. The lack of green spaces in urban areas further intensifies the problem, making it critical to implement solutions such as urban greening and community-focused resilience strategies.
