Western US Wildfires Undo Two Decades of Air Quality Progress (axios.com) 32
An anonymous reader quotes a report from Axios: Increasingly intensive and frequent wildfires in the western U.S. are deteriorating air quality and causing more premature deaths, a new study found. Fires have damaged federal efforts from the Environmental Protection Agency to improve air quality mainly through reductions in automobile emissions, per the study published Monday in The Lancet Planetary Health. From 2000 to 2020, air quality has worsened in the western U.S. due to wildfires. Black carbon concentrations have risen 55% on an annual basis, mostly due to the wildfires, researchers found. The fires have also caused an increase of 670 premature deaths per year in the region in the two-decade span. Meanwhile, the eastern U.S. had no major declines in air quality during the same time period.
Our air is supposed to be cleaner and cleaner due mostly to EPA regulations on emissions, but the fires have limited or erased these air-quality gains," said Jun Wang, the study's lead corresponding author and chair of the University of Iowa's Department of Chemical and Biochemical Engineering, in a statement. "[A]ll the efforts for the past 20 years by the EPA to make our air cleaner basically have been lost in fire-prone areas and downwind regions," Wang added. "We are losing ground."
[Daniel Swain, a climate scientist at UCLA] said the findings were consistent with other studies that contribute to the same overall picture that after the air quality regulations' great success, "the extremes of those air pollution episodes are actually now increasing again" due to wildfires. "On average, the air quality is still better, but the problem is, it's during these episodes of just-near apocalyptic conditions where we're really losing a lot of ground and that really is because the size and the intensity of wildfires has increased greatly," he said. Given climate change is a wildfire driver, keeping global heating to the lowest level possible will help. "But we're still going to see more warming no matter what moving forward, and so there will be further increases in the wildfire hazard," Swain said.

A forest burning releases much CO2, but it also gives the opportunity to a new forest to grow back. So, unless you pour concrete on the burned forest, the trees will grow back and over a few decades, the net CO2 of the operation will be zero.
Not quite the same outcome when we burn coal, gas or fuel.
Re: (Score:2)
Even when a forest burns, it does not release all of its carbon into the atmosphere.
Up to 40% of a tree's mass is in the root system, for example. The roots shrink when they try and permit oxygen to reach them so as long as the soil has drainage the decomposition is aerobic and most of the carbon in the root system is retained in the soil. Part of the tree also becomes charcoal and doesn't burn, and that part is also sequestered in the soil as new trees grow up and drop leaves on top of it which turn into s

Not even - the black mat layer deposited on the forest floor is net carbon sequestration.
Curiously my catalytic wood stove only produces white ash, which I put back in the garden soil, so I'm actually worse for sequestration than a forest fire. :)
Minimal fossil fuels, though.

The forest management efforts were originally blocked by government. Some of the first laws in California prohibited natives from doing controlled burns. Now we are literally going back to using native practices (the specific way they did their burns) in California because as it turns out even after we tried to wipe them out and nearly succeeded they still have retained more knowledge about how to do it well than we have managed to invent.

We need to take the initiative here and realize that we want people cutting their own firewood and burning it in EPA approved stoves to help with the problem. Instead, we ban it to save the planet, so it then can burn in uncontrolled and much dirtier methodologies, thus destroying the planet. The logic of this is beyond crazy, and is one of the reasons we have forest management problems....
