Nobody focuses on "black carbon," because we can't prevent wildfires, as they are a natural occurrence even without climate change. They are happening more frequently due to climate change, and firefighters try to control the burn in various ways, but it's a lot easier to work on the human-sourced CO2 and Methane than it is to address wildfires. The frequency and effect is a symptom of our own output.
If we can get a hold on our own emissions, wildfires will become less frequent as well.
That's one of the things I meant by "various methods," but a controlled burn isn't preventing the burn itself, just (hopefully) its spread. The fire is going to happen regardless, because it's a natural and necessary occurrence.
If our various governments could be bothered to actually penalize the worst polluters and invest in actually clean energy sources, the wildfires would sort themselves out; we're the ones that are making them worse.
