Disproportionate exposure to urban heat island intensity across major US cities

A. Hsu, G. Sheriff, et al.

Discover how urban heat stress impacts marginalized communities in the United States, revealing that people of color and low-income groups are disproportionately affected by higher urban heat island intensities. This crucial research was conducted by Angel Hsu, Glenn Sheriff, Tirthankar Chakraborty, and Diego Manya.

Abstract
Urban heat stress poses a significant public health risk. This study combines surface urban heat island (SUHI) data with census tract-level demographic data to investigate whether heat exposure disparities exist across income groups and racial/ethnic groups in the 175 largest urbanized areas of the continental United States. The research finds that people of color consistently live in areas with higher SUHI intensity than non-Hispanic whites, and a similar pattern is observed for those below the poverty line compared to those above twice the poverty line. These inequalities are not fully explained by income differences alone.
