Is that the winter of 2021?
No, there are winter vids of that city if you want to look for them. They all have steam rising from the river.
And the smoke coming out of smokestacks is white.
The young lady who makes Yakutsk vids are interesting. The city heat is from steam created by burning coal — which is local in coal mines.

You can find this sort of info in the bible of energy I have linked so often.
Those mines are near Yakutsk and Krasnoyarsk. About 1/10th of Russian joules are in coal form and 66% of it is domestic consumption — which is also information available from the relevant spreadsheet people really should be studying.
