That's a great question.
I worked at the Washington State Department of Natural Resources, where we dealt with forestry issues. Living in Washington state, we got to enjoy some of that smoke over the last two summers, so I'm very appreciative of the problem you talk about.
The modelling I talked about is from William Nordhaus. He talks about the economic costs and benefits. Any time you do modelling over 100 years, there is going to be variability; there's no question. He does not say that there are no costs; he clearly says that action needs to be taken to avoid specifically the problems you're talking about and their impacts. I don't want to leave the impression that no action is necessary, because the examples you give are legitimate.
The question is where you draw the line. How much do you do? How high is the cost? What he found in his modelling, with the requisite error margins, is that if you try to meet the 2°C target of the Paris climate accord, the economic costs outweigh the benefits.
Let me also say, having a background in forestry, that it's not just climate change, as you know, that is causing the problems with forest health. A better approach, rather than reducing CO2 emissions, may be to manage forest health. There's more than one issue. There's no question that warm summers increase the likelihood of the forest fires that you and I got to experience, but it's not the only approach we can take.
