Plus, humans can work for about 80-90 minutes at close to 100 F (albeit not comfortably)[1], so we're not really talking about conditions that would kill people. One can extrapolate, of course, but it's quite possible that the servers would break down before the humans do.
The point of this is: who cares if the data center is warm/hot? It's as hot as that inside a mascot suit at a theme park, so they build cooling mechanisms into them. Tools exist for a reason, and it is somewhat ironic that we prematurely assume that our creations require the same environment for "comfortable" survival that we do. The animistic tendencies we have may not just be cultural.
The point is, talking about how we can survive in freezing environments does NOT demonstrate that climate control (or rather, local microclimate control around your body) is just creature comfort.
