This is an interesting question. I wonder if the crystals are a natural energy source, heating the city and the surrounding area. It is also possible that the arctic conditions around the city were seasonal, as with the rest of Equestria and that the city's ponies, now they are restored, are able to wrap-up winter as efficiently in their lands here in the north as ponies elsewhere do further south.
