Basically nullifying every air pollution effort for years. Reducing CA wildfire should be environmentalist number 1 priority.

Wouldn't the proactive solution of controlled burns would also pollute the air? Is there another solution?

They would burn less at once, so peak pollution rates would be much much lower.

Ah yes.. flatten the curve.

It seems clear that the Western US is going to burn until the fuel is gone in enough places that megafires can't develop easily. It's like ecological herd immunity. Most affected states are still in the reactive firefighting mode rather than thinking how to get ahead of the curve by removing a century of fuel accumulated from determined fire suppression. There's no question rising temperatures make things worse, but…

It's not just fire suppression. We've got a trifecta of drought, bark beetle infestation and fire suppression (aka, tree density).[0] It's the killer combo . [0] https://www.fs.fed.us/psw/topics/tree_mortality/california/i...

This needs more upvotes. I agree that our fire management hasn't been great, but there is more to it than that. Climate change is driving both more fuel and deeper droughts, and making better conditions for bark beetles. There isn't a single answer to this.

ideologues are able to turn any event into evidence for their perspective. I'm not a climate change denier, I just agree with you that the real issue is humankind's fire suppression. There are a bunch of things that could be done, but no one is happy to support it. Selective logging, brush clearing, not putting multi-million dollar homes in the forest. etc.

"Selective logging" usually means removing the big, healthy, valuable trees and not the brush and dead wood that provide the fuel, but are not worth the effort to clear financially. It's expensive to do it well.

I agree too, despite the strong comment above.

Still, fire suppression is the 800 pound gorilla. We're not just seeing fires in the conifer-dominated Sierra. It's also in the savannah and scrub zones as well. These all burned regular in prehistoric times.

Saw something similar to this in the Inland Empire during the camp fires up at Big Bear. I remember attending a Civil War reenactment at the time and it was raining ash and the smoke was so thick you couldn't see the sun. It was so surreal.

we had a milder version of this kind of pollution in LA for the past few days, although today seems almost back to normal. over the weekend, the orange haziness of the sky was pretty noticeable.
