As the world continues to warm, heat waves have become more frequent, intense, and deadly. While everyone is affected by extreme heat, vulnerable communities bear the brunt of its impacts. From the elderly to outdoor workers, from low-income families to people with disabilities, the heat crisis is also an equity crisis.
Older adults are particularly susceptible to heat-related illness and death. As the body ages, its ability to regulate temperature diminishes. Chronic conditions like heart disease and diabetes, common among seniors, are exacerbated by extreme heat. Many elderly people live on fixed incomes and cannot afford air conditioning or high electricity bills.
Outdoor workers face dangerous conditions daily. Farmworkers, construction workers, and delivery drivers often labor in temperatures exceeding 100°F with inadequate breaks, shade, or water. Heat is now the leading weather-related killer among U.S. workers, yet most states lack workplace heat standards.
Low-income communities, often communities of color, experience the urban heat island effect most severely. These neighborhoods have less tree cover and more heat-absorbing infrastructure. Residents may lack air conditioning or fear using it due to energy costs.
Solutions exist but require political will. Federal heat standards for workers, investments in urban greening, utility assistance programs, and expanded cooling centers can all help. Most importantly, vulnerable communities must be centered in climate adaptation planning.
