The researchers took satellite measurements of land surface temperatures over the past 20 years and cross-referenced them against the geographical coordinates of more than 8400 AI data centres. Recognising that surface temperature could be affected by other factors, the researchers chose to focus their investigation on data centres located away from densely populated areas. They discovered that land surface temperatures increased by an average of 2°C (3.6°F) in the months after an AI data centre started operations. In the most extreme cases, the increase in temperature was 9.1°C (16.4°F). The effect wasn’t limited to the immediate surroundings of the data centres: the team found increased temperatures up to 10 kilometres away. Seven kilometres away, there was only a 30 per cent reduction in the intensity.

That is wild, but I guess not unexpected. If you have a 1GW datacenter, that 1GW has to go somewhere. 1GW being what a small city might use.
