Which is particularly beneficial for Russia as their useless land will become prime agricultural land and they'll have access to more warm water ports.
They say the same for Canada and it doesn't work like that. It isn't going to warm enough, increased variability is even worse for crops, and the soil typically isn't good for agriculture anyway even if the temperature was better.
The Russian information doctrine is to fuel any fire that has two sides. They don't actually pick sides, they just want nations more divided, because nation that is divided cannot function properly.
They definitely pick sides. There are cases where they'll specifically support the other side for a specific rally or action if they think it can cause disruption and strife, but those cases are an exception to the rule.
