INSUFFICIENT LEANING
Recorded sources

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that wildfires can ignite naturally from lightning strikes without any human involvement?

Unclear. Several peer-reviewed sources state that lightning ignites wildfires, with one study documenting over 17,000 naturally ignited wildfires in Arizona and New Mexico and another attributing 45% of Alberta wildfires to lightning. All of these cover only specific regions or mention ignition in passing, so they support the claim in part rather than fully.
