The only good news is it will envelop D.C. today. Fitting to force them to smell their passive dismissal of the global catastrophe of climate change.

In addition to climate change effects, do you think that preventing wildfires for decades contributes at all? My understanding is that managed burns can be useful at preventing the worst fire fires.

The fact that some trees only germinate in the presence of wildfires points to wildfires being a very natural and pre-human thing. And recent wildfire management practices are likely a strong factor in recent wildfires.

Canadian here. Sky looked like Breaking Bad in real life. Also, before this week, I'd never seen the weather app show a yellow map before for air quality.

Eastern Canada, perhaps? Because B.C. wildfires have made Washington maps go to "very unhealthy" (AQI 201-300), so I'm sure B.C. was above that.

(I'm not sure what "yellow" means where you're at. It's "healthy" according to https://www.airnow.gov/aqi/aqi-basics/).

I don't think that's as relevant for these huge regions of remote forest in Canada as it is for the lower 48 of the USA where you have a lot of population density and ranching and farming in the dry areas that historically burned on a regular basis. Maybe someone in rural Ontario knows the full story.
