This documentary is so astoundingly anti science it is incredible,. There are scores of dendrochronology studies looking the the past 10,000 years that show California has had a very large number of much worse drought periods and much more wide, severe and sustained wildfires and wildfire periods.
When this film says "largest" they mean the most property damage because -- guess what -- there is ten times as much property value in California s 40 years ago, and thousands of times more property value than 200 years ago.
Now if you go back 300 or 1,500 years, a blink of the eye in terms of climate, these fires, exacerbated by California farm, housing development, and ironically fire management polices we now know make it worse, they last 200 years has bene bad. But on the scale of 14,000 years there have been twenty periods, from a few decades to a to three centuries long, that saw over twice as many worse fires per year than today.
newsflash: the continental west/southwest of North America has been experience desertification process for over ten thousand years, just like south west of Africa and also like the Sahara (which had rivers, and megafauna up tot 5,000 years ago
