It wasn’t 1-2 days, it was several weeks. And I’m not saying that this is a 100% certain situation. I’m saying, there is a decent probability it’s going to get worse over time due to climate change.
No, the air quality wasn't the "worst ever" (not here at least) for several weeks- That is not the truth. In any case I've tried to answer your questions the best that I can and I am not inclined to care why you are on presenting this as truth.
It was bad, for more than 1 or two days, right ?
Here is the truth:
Due to climate change, forest fires are likely to get worse over time on average, which should impact Seattle air quality over time. Is this certain ? No, but there is a substantial probability it’s happening.
