Data centers warming nearby land by up to 16°C, study warns
New research shows data centers create heat islands, pushing surrounding land temperatures up to 16°C and impacting millions who live nearby.
New analyses show data centers, the digital hubs behind streaming, cloud storage, and AI services, act like heat islands. In several regions, land within the immediate vicinity of a data center is warming far more quickly than farther away—some estimates put surrounding temperatures up to 16 degrees Celsius higher, especially during peak operation. The effect isn't just a climate curiosity; it can shape local energy demand, cooling needs for nearby buildings, and the everyday comfort of communities living nearby. Roughly 340 million people now live within 6.2 miles of a data center.
A separate study focusing on AI data centers finds a more modest but still significant rise in local temperatures—about 2°C on average—potentially affecting hundreds of millions who live within a few miles of these facilities.
Experts say the heat islands stem from how data centers dissipate heat: servers generate heat, cooling systems vent it into surrounding air and soil. When centers cluster near urban areas, the cumulative warming can create microclimates that strain power grids and cooling infrastructure during heat waves. The scale of exposure—a large portion of the population within tens of miles of such facilities—calls for action.
Mitigation options include energy-efficient designs, advanced liquid cooling, and integrating renewable energy to reduce net heat; urban planners can add green spaces and reflective surfaces to offset localized warming. The bottom line: data centers are essential for a connected world, but smarter siting, cooling, and climate safeguards are needed.
