    > The mean air temperature on the upwind side of the facility was approximately 42.7 °C, increasing to 43.5 °C in the neighborhood near the eastern boundary of the data center campus on the downwind side. The observed ΔT of approximately 0.8 °C extended roughly 500 m downwind

    Seems like we do observe heating but a much smaller average delta T than the title would hint at; I didn't see a max distance they evaluated over, seems like 500-1000m was their search window from their text. The next paragraph discusses how one of the sites they compare to is a relatively lower average temperate than the rest of Phoenix. Not really convinced by this methodology. Seems like doing something in a flat field with an array of temperature sensors would be a much more robust way to look at heating effects over some reasonable distance

    Reminder: 4 degrees = 0.0698131701 rad

    (article says 2.2C, btw)

    Out of curiosity, how are large data centers zoned?
    • matherial 3 minutes ago
      Zoning is a per-city and per-county thing. Traditionally, they usually occupied some sort of commercial / light industrial zones, the same as office parks and warehouses. But hyperscale stuff often requires one-off variances / rezoning.

      industry or heavy commercial, which is where some minor wrinkles have been coming up because they usually don't need special permission to build as long as the zoning fits

      honestly I'm sure other industrial uses can cause temperature increases too, the nature of industrial zoning on its own tends to reduce green space which can lead to the heat island effect, so this is at least partially because hating on data centers is the issue du jour

      My first real job was in McKinney, sad to hear they are all dead.

    All I can think of when reading this was Hank Hill yelling at his neighbor: "Dale you giblet-head, we live in Texas, where it's already 110 in the summer. And if it gets one degree hotter I'm gonna kick your ass!" [1]

    "The attribution of this warming to data center waste heat is supported by the consistent alignment of the temperature signal with the prevailing wind direction across multiple sites, dates, and meteorological conditions. "

    Well, no? That could also mean that the heat island effect of the (statutorily mandated) employee parking lot is causal.
