LONDON, April 9 —
- Heat Impact: Data centers may raise nearby land temperatures by an average of 3.6°F.
- Extreme Cases: Some locations recorded increases of up to 16.4°F near large facilities.
- Population Effect: Temperature changes may affect more than 340 million people worldwide.
- Distance Spread: Heat impacts were detected as far as 6.2 miles from data centers.
- Study Scope: Researchers analyzed over 6,000 data centers globally using satellite temperature data spanning 20 years.
Hidden environmental cost of AI infrastructure
The massive data centers powering artificial intelligence systems may be creating localized “heat islands,” warming surrounding land and communities, according to new research.
Scientists analyzed temperature data collected over two decades and compared it with the locations of large AI-focused data centers around the world.
Rising temperatures near hyperscale facilities
The study found that temperatures increased by an average of 3.6 degrees Fahrenheit after a data center began operations, with some areas experiencing increases as high as 16.4 degrees.
Researchers focused on more than 6,000 facilities located outside major urban zones to isolate the effect of data center heat from other industrial or residential sources.
Impacts extend beyond facility boundaries
Temperature changes were observed up to 6.2 miles from the facilities, potentially affecting more than 340 million people globally.
Researchers highlighted regions such as Mexico’s Bajio technology corridor and Spain’s Aragon data center hub, where unexplained warming trends appeared near clusters of hyperscale facilities.
Debate over environmental risks
Some experts say the findings highlight a previously overlooked environmental impact of AI infrastructure.
However, other researchers caution that more studies are needed to verify the results, noting that energy consumption and emissions from electricity generation remain the larger climate concern tied to data centers.
Scientists say the rapid expansion of AI infrastructure makes it urgent to examine ways to reduce environmental impacts while maintaining technological progress.
