On summer afternoons in Raleigh, parts of downtown already run several degrees hotter than surrounding neighborhoods, a gap the city has spent years documenting through its urban heat-island mapping program. Now a new study suggests that North Carolina’s accelerating data center buildout could make those hot spots worse and create new ones in communities that have never had to think about industrial heat.
A preprint posted on arXiv by researchers affiliated with the University of Cambridge examined two decades of satellite land-surface temperature data, from 2004 through 2024, around thousands of hyperscale data centers worldwide. Their finding: after a large facility began operating, the land surface within its immediate vicinity warmed by an average of roughly 2 degrees Celsius (about 3.6 degrees Fahrenheit). At outlier sites, the increase reached approximately 9 degrees Celsius (around 16 degrees Fahrenheit). The study has not yet undergone formal peer review, and its figures reflect land-surface readings, which tend to run higher than the ambient air temperatures people actually feel. Still, the scale of the warming it documents has drawn attention in states where data center construction is booming, and few states fit that description better than North Carolina.
This article, published in May 2026, is based on a review of publicly available documents and the preprint study. No data center operators with known North Carolina footprints, including Meta, Apple, and Google, responded to requests for comment. No community residents or advocacy groups were interviewed for this piece, which limits its perspective to what the documentary record shows. Readers should weigh that gap when evaluating the claims below.
Why North Carolina is a focal point
The state has become one of the East Coast’s most aggressive recruiters of hyperscale computing facilities. Apple operates a campus in Catawba County. Google has invested in Lenoir. Meta has built in the Raleigh-Durham corridor, and multiple additional projects are in various stages of permitting across Wake, Chatham, and Mecklenburg counties. The North Carolina Energy Policy Task Force 2026 report, published by the governor’s office, identifies data centers as a primary driver behind the state’s surging electricity demand and references specific North Carolina Utilities Commission filings that detail how planners are scrambling to keep pace.
Duke Energy Carolinas and Duke Energy Progress, in their 2025 Carolinas Resource Plan filed under NCUC Docket E-100, Sub 207, treat data centers as a separate forecasting category because their consumption patterns differ so sharply from ordinary commercial buildings. The filing lays out scenario designs and economic development adjustments that shape demand projections years into the future. What it does not address, and what no state regulatory document currently addresses, is the thermal output those facilities will produce or how waste heat might affect the people living nearby.
The gap between global data and local impact
The Cambridge-affiliated preprint offers the most specific temperature measurements available, but its numbers are global averages drawn from satellite observations, not ground-level thermometer readings collected at North Carolina sites. Based on a review of available research as of May 2026, no publicly available analysis appears to have isolated land-surface temperature changes around individual data center facilities in places like Mecklenburg County or the Research Triangle, where much of the state’s growth is concentrated. Local climate, vegetation cover, building density, and facility design all influence how much waste heat a data center adds to its surroundings, which means applying worldwide averages directly to any single community requires caution.
North Carolina does have the scientific infrastructure to close that gap. The NC State Climate Office has conducted urban heat-island temperature mapping campaigns across the Raleigh and Durham area, using NOAA-backed methods and local partners. Raleigh’s own mapping program feeds results into mitigation planning. Together, these efforts establish that urban heat is already being measured in the state, providing a baseline against which new industrial heat sources could be evaluated. The missing step is applying those tools specifically to data center corridors.
What no one is disclosing
Several pieces of information that residents and planners would need to assess local risk remain absent from the public record as of May 2026.
Neither the Task Force report nor the Duke Energy filing quantifies how many people live near planned or operating data center sites. Population exposure estimates, which the arXiv preprint addresses only at a global scale, have not been produced at the state level by any North Carolina agency identified in available documents. Without that data, the question of whether lower-income or historically marginalized neighborhoods bear disproportionate heat burdens from these facilities remains open rather than answered.
Direct statements from data center operators about heat mitigation plans for their North Carolina campuses are also missing. Meta, Apple, and Google, all of which have known facilities or investments in the state, did not respond to requests for comment for this article. The NCUC filings detail electricity demand scenarios but say nothing about cooling infrastructure design, expected thermal discharge, or commitments to offset localized warming. Whether operators are investing in green roofs, reflective surfaces, or waste-heat reuse for district energy is not confirmed by any primary document reviewed for this article. It is also unclear how much waste heat is discharged into the air versus into water systems, a distinction that matters both for temperature and for the water-supply concerns that have surfaced in other data center markets.
Eastern and central North Carolina already experience humid summers and frequent heat advisories, conditions that can amplify the health impact of even modest temperature increases. Yet no state or municipal report examined for this story directly models how additional land-surface warming from data centers might interact with existing urban heat islands or projected climate change. Policymakers and residents are left to infer risk from global averages rather than locally tailored assessments.
Steps communities and regulators can take
Residents near proposed campuses do not have to wait for peer-reviewed local data to start pushing for accountability. Environmental review processes for large data centers typically focus on noise, traffic, and water use. Community members can request that those reviews explicitly include land-surface temperature modeling and long-term thermal monitoring. Neighborhood groups can also press for public disclosure of cooling system designs and expected waste-heat discharge, information that is conspicuously absent from current regulatory filings.
City and county governments can fold data centers into existing heat resilience planning. Raleigh’s mapping tools already identify where heat concentrates; extending that analysis to areas where large facilities are proposed is a logical next step. Local planners could also explore zoning or design standards that require high-albedo roofs, vegetated buffers, or on-site heat reuse where technically feasible, treating thermal impacts as a core part of land-use decisions rather than an afterthought. Prioritizing tree canopy, reflective pavement, and shaded transit stops near data center zones would build on strategies the city already uses elsewhere.
Why thermal monitoring belongs in North Carolina’s next regulatory docket
At the state level, regulators overseeing utility resource plans could require more granular information about where large data center loads are expected to connect and how those locations overlap with vulnerable populations. Current filings focus on megawatts. Future dockets could reasonably ask utilities and developers to submit temperature impact assessments alongside load forecasts. That would not resolve every uncertainty in the Cambridge-led study, but it would begin translating global satellite findings into site-specific evidence that North Carolinians can weigh against the jobs, tax revenue, and economic development that data centers also bring.
