Abstract

Environmental injustices in the United States are rooted in structural racism, particularly policies of racial segregation and disinvestment such as redlining that have produced enduring inequalities in the built environment and population health. This concept paper examines extreme heat as a racialized environmental exposure in Buffalo, New York—a post-industrial Great Lakes city increasingly framed as a “climate haven”. While such designations suggest relative protection from climate risk, they obscure the socio-spatial inequalities that shape uneven vulnerability on the ground. Drawing on a structural racism framework and insights from urban political economy, this study argues that extreme heat vulnerability in Buffalo is not incidental but produced through historically embedded patterns of disinvestment in housing, infrastructure, and environmental resources. Neighborhoods such as the East Side, Black Rock, and the West Side exhibit heightened exposure due to concentrations of thermally inefficient housing, limited tree canopy and green space, and unequal access to cooling resources. These conditions reflect the material legacy of segregation and uneven urban development, which continue to structure differential capacity to adapt to rising temperatures. Although extreme heat is widely recognized as a major public health threat, it remains underexamined in mid-sized northern and Rust Belt cities, where risk is often perceived as episodic rather than structurally produced. This paper addresses this gap by advancing a conceptual critique of the “climate haven” narrative, demonstrating that relative geographic advantage does not equate to equitable resilience. By theorizing extreme heat as a mechanism through which structural racism is reproduced, this study highlights the need for place-based, justice-oriented climate adaptation strategies that confront the historical and institutional drivers of vulnerability in Great Lakes cities.
