Data Centers Create Heat Islands Affecting 340 Million People, Study Finds

A non-peer-reviewed paper published on Arxiv by nine researchers from institutions including the University of Cambridge and Nanyang Technological University reveals that data centers generate significant heat island effects. Analyzing 20 years of remote land-surface sensor temperature data from 6,733 facilities, the study found average temperature increases of 3.6°F (2°C) in surrounding areas, with extreme cases reaching 16.4°F (9.1°C). These thermal effects can extend up to 6 miles (10 kilometers) from the centers, potentially impacting over 340 million people globally. Harvard researcher and architect Marina Otero Verzier, who studies the ecological impact of data centers, argues for a moratorium on unfettered construction and stricter regulatory frameworks with public oversight. She notes that while eco-social designs exist, industry implementation lags behind hyperscale growth. The data center market reached $350 billion globally last year, nearly doubling from pre-pandemic levels, with U.S. design and construction fees projected to exceed $150 billion by 2030. The study's findings align with growing research on data center expansion impacts, as communities near these facilities report noticeable environmental changes.
