Happens every year it's become normal mostly in the summer..This looks pretty horrific, again. Are our Californians doing OK?
Actually, check the map of the Camp Fire: https://google.org/crisismap/google.com/2018-camp-fireThe undergrowth is part of the problem; and the fact that the weather has become more favorable for large fires is another factor.
What you need is more rain & snow. The way you get that is, well, California knows very well how to do that. That's why they lead the country in environmental laws.
That is one thing I won't miss about Alberta, breathing in smoke from forest fires for 4-5 months of the year. Often we had to run the air conditioning just to clear out the haze and such.
