Ever heard of pine beetles? Looked into what causes them to survive winters that used to control the population?

Seen the effects they have on tree populations and the health of forests?

Yes. Yes.

Yes.

The relatively warm winters that allowed pine beetles to survive (I think it takes 10 days at -20C to kill them; ymmv) lasted a few years. It may still be going on.

The pine beetle is one of the supporting arguments for climate change---irrespective of arguments about cause. And it is not about drought.

So I conclude your comment is not relevant to mine.
