2023 marked the hottest year recorded in human history, with predictions indicating a worsening global trend. In early June 2024, southern California experienced an extreme heat dome, with temperatures rising into the triple digits. Currently, heat alerts affect over 16 million people across California, Nevada, Arizona, Utah, and New Mexico. This escalating situation is not confined to the United States nor limited to the present; it is a manifestation of the intensifying impacts of climate change. Regions previously unacquainted with extreme heat are struggling to adapt, while areas accustomed to high temperatures are becoming increasingly uninhabitable.

Heat is not merely a climate issue; it disproportionately affects individuals based on geographic location, race, and socioeconomic status, among other factors. In this episode, we sit down with Dr. Bharat Venkat, Associate Professor at the Institute for Society & Genetics, the Department of History, and the Department of Anthropology at UCLA, to delve into the concept of thermal inequality. We explore how Dr. Venkat developed an interest in this subject and examine the origins of thermal inequality. Our discussion addresses the populations most impacted by heat inequality, focusing on the Los Angeles area. We also touch upon critical topics such as urban design, socioeconomic disparities, and their intersection with heat. Finally, we contemplate the future of thermal inequality and potential solutions to mitigate its effects.

Dr. Bharat Jayram Venkat is an Associate Professor at UCLA with joint appointments in the Institute for Society & Genetics, the Department of History, and the Department of Anthropology. His research spans science, medicine, climate, race, and design. His notable works include his award-winning book At the Limits of Cure and his current project on thermal inequality, Swelter: A History of Our Bodies in a Warming World.
