No. The majority of fires are not started by arsonists. This time it was lightning. Two years ago, it was strong winds and power lines. There are the occasional accidents, like the case where a hot car pulled over and ignited some dry leaves. Also, a lot of California is a chaparral. It's an ecosystem shaped by wildfires. They are expected. Those locations must burn regularly, as they have been doing for thousands of years. This is completely unrelated to, say, a tropical forest. Which is not expected to have more than isolated, occasional fires.
