Three and a half minute video, apparently taken by a Garman dashcam in a car that does not move for the duration of the video.
"But there is a claim that these fires were arson."
Only a small percentage of them.
The issue is not how the fire starts. Some will start because of arsonists. Some will start because of unavoidable events. Some will start because of avoidable events. The NUMBER of fires may not be much of function of climate change at all. But, there WILL be fires.
The issue is the life of each fire after the fire starts, the amount of damage the fire does before its done, and whether the fire can be "put out" --- a given fire can easily do thousands of times as much damage when high winds spread it faster than it can be contained. Higher wind speeds are a growing function of what we haven't bothered to do about climate change causes.
