Take for example, here is a map of active fires around the globe, right now:

By "fires" do they mean fores fires? Controlled fires to burn crops, or burn land to clear it for crops? House fires? Bonfires? Campfires? Fires in fireplaces?

Ignition is a fundamental for fire to happen, and humans cause WAY more ignition events than nature does.

A car causes hundreds of ignition effects per minute. But, I'm guessing you mean a certain kind of ignition?

The timing and frequency of these events directly influence the frequency of fires.

The timing and frequency of things like lighting a fire directly influence the frequency of fires? Do you mean the frequency of out-of-control fires? Because otherwise that seems like a pretty obvious conclusion.
