I want to be clear, I'm not a climate change denialist -- climate change is real, and it's an imminent threat -- but forest fires are not exploding simply due to climate change. The reality is, once you've built up enough fuel, the only way out is by burning it. We no longer suppress wildfires to the same extent, and so they grow much larger.
Also, for what it's worth, the PNW had wildfire season prior to the implementation of the 10am policy. In 1895, in Tacoma, WA, Mark Twain joked about the wildfire smoke: "Really, your scenery is wonderful. It is quite out of sight."[0]
The reality is, our forests grew up alongside not only natural wildfires, but human-instigated wildfires for the purposes of ecosystem management by native tribes. We spent a couple hundred years trying to implement a "better" system, by ignoring the natural processes of the past 10,000 years. It shouldn't be a surprise that we're in a bad place now.
