Anyway about the specific matter i'm no expert in California wildfires. My modest impression is that it's the consequence of many different causes: bad forest management,

insufficient resources for the local fire departments, physics (wood sometime burns), unreasonable green ideologies, political inefficiencies and corruption, etc...

Me thinks: there is no one single villain.

Too often we tend to reduce bad events to a single cause, because it's simple and reassuring, but reality is way more complex.
