Stop with the strawman. A dryer, hotter climate will cause fires to get larger and do more damage. No one says that a hotter climate will cause the initial burn spontaneously.
I'd say it qualifies.
Dried out conditions make initial triggers (like lightning or arson) more likely to have disastrous consequences.
What I mean is you're being needlessly defensive. The strawman completely fails even on its own terms.
Regardless of the side you fall on, making something significantly worse is still a problem to be solved.
