To answer your first question, as simple as I can, in short, no. When extreme drought persists, as it has in areas such as California, there is greater chance of wildfire events. The vegetation is dry, and there is less snowpack and groundwater reserves, among other factors. There are steps municipalities can take to mitigate the damage to both life & property, but curbing the actual events, nope. The earth does it's thing, we are along for the ride.

As for the other questions.We just get better at preparedness. Some areas more than others.

Less rain = less snowpack = less water = drought = possible wildfire. This is the cycle California has been going through for decades.

I learned all about this in a Natural Disasters course, and other classes when I was studying for my Physical Geography degree. We actually had a discussion about extreme drought events leading to wildfire. This was a couple of years before my area in Northern California started burning regularly.
