There are company of Russian photographers that travel around Russia and world taking pictures of everything they see. Recently they decided to split up; one of them went to Africa to make a picture story and the other one went to one of the mining towns in Siberia. Just compare it, +40C (+95F) in Africa and -40C (-40F) in Siberia.
It is kinda funny to be there at nights. If you open a window, you will hardly close it after 5 minutes.
One of cozy streets. The temperature outdoors is -42C (-44F).

Many houses have boiler installations which burn coal.
Because of that, the whole city is being smog-immersed and all snow grays out the next day it falls.
