Briefings
A 2026 study published in Environmental Research Letters analyzed 13 years of satellite data to investigate whether hyperscale data centers significantly warm surrounding land. The research found that while a prior study suggested data centers could raise temperatures by up to 9 degrees Celsius, the new analysis indicates that server waste heat causes minimal nighttime surface warming. Instead, building materials tend to cool ground temperatures during the day, contradicting the earlier hypothesis of widespread heating.
Key points
- A 2026 study published in Environmental Research Letters analyzed 13 years of satellite data to investigate whether hyperscale data centers significantly warm surrounding land.
- Server waste heat causes minimal nighttime surface warming, while building materials tend to cool ground temperatures during the day.
Context
This research challenges a previous study that suggested data centers could raise temperatures by up to 9 degrees Celsius on average, up to 6.2 miles away. The findings are based on 13 years of satellite data, which reveal that server waste heat causes minimal nighttime surface warming.
Limitations
The study covers only 13 years of satellite data, which may not capture long-term climate trends or extreme weather events. The analysis relies on satellite observations, which may have limitations in remote or data-sparse regions. The study does not account for local microclimates or other factors that could influence ground temperature variations.
