We've graduated to the Purple category now...."very unhealthy."
It only got that bad here for a little bit ... highs in the 80s the last few days vs. over 100 over the long weekend so that helped a bit ... plus it's been a bit windy, which has fueled the fires of course, but at least it pushed some of the smoke out of the valley.
I read that smoke had drifted at least as far as Oklahoma.
So what are we looking at here?
1. Climate change ... global warming means longer sustained periods of heat, more wind, and more frequent thuunderstorms which spark fires. It also means an increasing frequency of rain as opposed to snow which means drier overall conditions. It does mean heavier rain showers, which will help when they come, but it seems that's not enough to compensate for these other things.
2. Federal neglect ... for the first couple days of the fire season, Washington for the first time ever provided no funds for fire suppression ... I assume this reflects a combination of belt-tightening and related ideological demands for state self-reliance.They did reverse themselves, but only after fires blew up that might have been suppressed.
3. Poor forest management. Decades of extremely aggressive fire suppression in areas that had previously adapted to regular firen combined with intense logging particularly of the biggest trees, left forests covered with dry fuel ... needles, grass, and tree bark ... that smolders just like campfire tinder while creating avenues for oxygen that would otherwise be blocked by dense trees to get in. There's a myth that more logging would ameliorate the problem, but forest ecologists, silviculturists, and fire experts all say the only logging that would help would be removal of small trees and shrubs and dead plant material ... which is unprofitable. Now I think you can make the case that we should log those trees instead of just letting them burn anyway, especially if (and I don't know whether this is true) that means less carbon combustion when the forest does burn. But that does mean more fire.
4. Nature. Fire's been a fact of life around these parts for millennia, and air pollution tends to settle in cool valleys like ours. It sucks, but that's part of the price of living here.
