If the question is whether AI data centers end up raising temperatures in a region, the answer is: 2.2 °C

Arizona State University researchers found that AI data centers in metro Phoenix can raise nearby air temperatures by up to 2.2°C.

The warming effect is detectable as far as 500 meters from the facilities and could grow as installed capacity expands.

The study highlights a new urban and public-health concern beyond energy and water use: data centers may heat entire neighborhoods.

The findings could influence where and how new AI infrastructure is built in cities such as Zaragoza, where large projects by Amazon and Microsoft are planned.
