Field measurements of neighborhood-scale air temperature impacts of data centers
Points and comments are a snapshot, not live.
A study measured air temperature increases downwind of data centers in Phoenix.
The paper reports field measurements near data centers in Phoenix, finding that air temperatures downwind were up to 2.2°C warmer than upwind, with an average increase of 0.8°C extending roughly 500 meters. The authors attribute this to waste heat from air-cooled condenser arrays, which discharge air 8-14°C above ambient. The study focuses on sites adjacent to residential neighborhoods, highlighting potential urban heat island impacts from data center cooling.
What commenters are saying
Commenters are skeptical of the study's methodology, arguing that the measured temperature differences could be caused by the heat island effect of parking lots or lack of shade, not data center waste heat. Some note that poor zoning places data centers next to homes, and that industrial areas generally contribute to local warming. Others dismiss the findings as a "nothing burger" or point out that thermal power plants reject far more heat without comparable effects.
