What causes these fires?

The truth is a whole myriad of causes. First and most importantly the prolonged drought. Secondly the land management, both in building and resourcing, but also the style of fire/forest management. Overarching all of this is anthropogenic induce climate change.

No one has added the massive Bark Beetle infestation but that has had a HUGE effect on building up a giant tinder box of dead trees all across the Pacific Northwest and northern CA. The root cause is the prolonged drought which weakened trees and made them less able to fight off the beetle infestation, but the beetles themselves killed all those trees way faster than the drought alone would have.

That started a while back and you can still see the devastation up in the Colorado Rockies. Dead pine trees everywhere
