I wonder if the giant crater beneath Atlas is an open caldera volcano.

If it is, then the heat rising up to Atlas could actually bring the temperature in Atlas up enough for it to not be unbearably cold, which could in turn offer some explanation to why Weiss wasn't wearing any winter wear in her character short. It could also serve as inspiration for Atlas to make those orange Dust heaters that are scattered around Argus - take a Dust that's capable of generating lava, and use it to heat a city.
