The people of California who are affected by the frequency and severity of these fires don't need to be told for the umpteenth time why they are happening. They need actual measures in place to control the situation and mitigate the effects .If one finds oneself in the midst of something like this , then the worst is already happening - whatever the cause.
Given that California is the wealthiest State in the whole of the U.S.A. then funds are going to have to be channeled into better managing the land outside the major cities - all those wild, forested areas and, grassy scrubland. The minimum one should expect is that there are, at least, large enough fire-breaks around the major conurbations to protect them.
