74 minute video sent by a friend with the title: what's causing these weird fires. i have not had time to watch it but the friend isn't a huckleberry. i'll paste her intro just below; 

The guy in this youtube video (below is link) is a forensic arborist . He says NO WAY this is natural. He explains why the ashes are white, that it has to be 2500 degrees to make the glass in cars and houses evaporate and how melted aluminum from car rims are sitting on top of unburned leaves. This was videoed a month before the LA fires. I will see if there is a new one, too. There are a few suggestions at the very end on grounding your house to avoid this situation. Maybe worth looking into if anyone has time.
