Forest mismanagement is, in fact, one reason for global warming. I wouldn't disagree with you there, although we'd probably disagree about what a properly-managed forest would look like. 

It also needs to be said that  BLM and the state management agency are probably doing things that made sense under a mid-20th century climate regime. It's just that nature is ahead of us now, and those things no longer make sense. 

Of course, the things that make sense now are politically impossible. And nobody could imagine the impacts of industrial logging and intensive carbon fuel use when those things were becoming the norm. In a few words: our way of life now is no longer sustainable and our problems with wildfires are a symptom of this.
