Data centers are creating 'heat islands' on land around them - warming them by up to 16 degrees, researchers warn

The rapid global expansion of data centers used to power artificial intelligence is creating “data heat islands” that significantly warm the surrounding environment, according to new research.

The study, led by researchers at the University of Cambridge, suggests that these vast AI data centers can increase local land surface temperatures by an average of 3.6 degrees Fahrenheit (2C), with some extreme cases recording rises of up to 16.4 degrees Fahrenheit (9.1C). This localized warming effect is estimated to affect more than 340 million people worldwide.

As the tech industry races to build “hyperscale” facilities — some spanning over a million square feet — to meet the computing demands of AI, researchers are warning of a lack of oversight regarding their environmental footprint.

There are still big gaps in our understanding of the impacts of data centers, even as they boom in number, Andrea Marinoni, associate professor at the University of Cambridge and an author of the study, told CNN.

1. Wow - that is astounding. Along with sucking up the water supplies, overloading the electric circuits,

What's not to like about our tech bros?

Getting tax breaks? Destroying land that could be used for more productive uses?

They'll be leaving once they've completed their carnage. Good luck to the state and local municipalities on getting recompense for failed agreements when they've gone (bankrupt or owners not found.)

2. K&R a million times

3. And this doesn't include the heating effect of burning fossil fuels to generate the copious amounts of electricity

that the data centers consume. Burning copious amounts of fossil fuels produces copious amounts of greenhouse gasses. Whose concentration in the atmosphere keeps increasing at increasing rates.

There's plenty of debate about what that amount of fossil-fuel fired generation is that can be ascribed to data centers. Some buy their electricity from wind, solar, and nuclear sources, but then the question is how much of that actually results in more wind, solar, and nuclear, and how much it simply results in less wind, solar, and nuclear (and thus more fossil-fueled) serving the rest of the electrical load.

So let's say a utility generates 80% of its electricity with fossil fuel, and 20% from wind.

A data center contracts with the utility for half that wind-generated electricity.

The utility still has the same amount of regular load to serve, and now must generate more from fossil fuel to make up for the wind-generated electricity that was serving the regular load but is now dedicated to the data center.

Until the utility builds more wind generation -- but that's wind generation that could have gone towards reducing the fossil-fueled part that's serving the regular load.

4. They are a cancer on the landscape of America. Let them in at your own peril.

5. If they are 1M sq ft,

They must have enormous roof tops for solar panels

6. Kick

7. How about building these centers on the moon and power them with solar or nuclear.

8. Well, Maybe If Superman Were Real.....🚀

10. I thought that was the plan Musk had in mind. I know he wanted to build some tech crap in space

so they could immune to rules, regulations and laws. That's if he can get the rockets launched without blowing up on the launchpad.

9. Yep. What's not to love? Accelerated climate change. Check. White Collar bloodbath. Check.

Data center locations uninhabitable. Check.

Trillions raided from the treasury to line the pockets of the magnificent 10. Check.

Public services decimated as "too expensive." Check

Health care decimated as "too expensive." Check.

What a paradise this world remade by AI will be.... for the top 0.1 percent.

11. What a crisis!

And it seems most don’t have a clue about this enormous cost on our environment. The news should be covering this all the time!

12. I think it is getting a lot of press coverage in "local" news outlets

with people who live near the current, under-construction, or planned sites (including those near the budding ICE concentration camps too) have really put up a fuss, and the subject of environmental impacts and costs, inevitably gets brought up.
