A massive data center hub is likely heating up a town outside London

Locals in Slough are sweltering during Britain’s hottest summer and say the constant hum of nearby data centers makes the town feel even hotter.
The town sits beside one of the world’s biggest data‑center hubs, and research suggests clustered centers can create “heat islands,” raising local temps by several degrees.
Operators say they use reflective roofs and green space to cut heat, but experts warn the scale and concentration of these facilities could still amplify local warming.
