Yes, but not in the way you're portraying it. The big shift downwards comes in a major shift in strategy in dealing with forest fires in the early to mid 1900s; it doesn't tell you much about the climate at the time. https://foresthistory.org/research-explore/us-forest-service...
> In 1935, the Forest Service established the so-called 10 a.m. policy, which decreed that every fire should be suppressed by 10 a.m. the day following its initial report. Other federal land management agencies quickly followed suit and joined the campaign to eliminate fire from the landscape.
I'm saying they haven't gotten better.
The drop in the 1930s-1950s shown in the wider chart has nothing to do with climate, and little to do with technology. It reflects a misguided change in fire management strategy (put out every fire ASAP), one that is now understood as a bad approach, because it causes build ups of unburnt brush that cause more dangerous, more intense fires.
No. People will keep working on it. But being unrealistic and continuing to live and consume like you did in the 00's because "anyway, tech will save us" is the worst comportment anybody can have.
That said, I backpacked in the Sierras this summer and alarmingly saw many old Pine stands recently dead from what I assume is the drought. I also find the perilous state of the arctic ocean ice, the seeming breakdown of typical jetstream patterns(probably linked to the arctic ice) and the sky-high CO2(resulting in ocean acidification as well as warming) all particularly concerning.

If you want to read about particularly the smoke, the books are broken up by year and chapters chronologically, his writings during September particularly tend to describe the smoke.
See:
> Approximately 1.8 million ha burned annually in California prehistorically (pre 1800). Our estimate of prehistoric annual area burned in California is 88% of the total annual wildfire area in the entire US during a decade (1994–2004) characterized as ‘‘extreme’’ regarding wildfires. The idea that US wildfire area of approximately two million ha annually is extreme is certainly a 20th or 21st century perspective. Skies were likely smoky much of the summer and fall in California during the prehistoric period.

> Many consider wildfire as an accelerating problem [...] however, important exceptions aside, the quantitative evidence available does not support these perceived overall trends.

Take this [1] paper for example I just happened upon. Look at this scary graphic they provide to convince the reader that wildfires are getting worse [2]. The paper goes on painting a terrible picture about the rising trend of wildfires in the U.S. Now let's look at the source for their graphic and look back further at earlier dates from the same source. [3] - kind of paints a different picture, no?
So at what point am I, an average citizen supposed to be worried enough that I do my own systematic reviews of the literature and see who is just sensationalizing the problem?
Maybe I'm the minority, maybe the "marketing" of global warming is exactly as it should be if the problem is indeed as dire as many would have me believe, but the obvious sensationalism just makes me wonder if everyone trying to sell me on this fear has just bought into the hype and as such I'll be a hard sell on this issue, because if it was real and dire - I doubt there would be such obvious sensationalism every time I look into it.
