Wildfire intensity is affected by a combination of irresponsible forest or brush management, and obscured by climate change propaganda. Fire-prone conditions are worsened by not building fire breaks, never clearing of undergrowth, and not clearing of vegetation around human housing. Wildfires are more dangerous to humans with a high fuel load. Management of forest fuel load is far more important than having "natural" forests.
Another problem in California is the continued spread of invasive grasses which dry out quickly in CA weather. They provide “fine fuels” for fires in the grasslands and chaparral, particularly along the coast.
The odd California policy of "road diets", narrowing roads to handle less traffic “for safety,” caused traffic jams when residents tried to flee Paradise, California, when 85 people were killed in the Camp Fire of 2018 ... started by a faulty electric transmission line.
The August 2020 fires have been ignited by dry lightning, lightning that occurs without rain hitting the ground. This is unusual, but has nothing to do with climate change. It is claimed that 90 percent of US wildfires are man made, some arson.
