True.
The root cause of the western fires that have been getting worse is the stressed biosphere and local ecosystems that are dying out. As temperature and rainfall patterns change, entire ecosystems are basically living in the wrong place to thrive.
So for example, you might have a conifer forest that has existed in one place for thousands and thousands of years that needs a certain amount of cool weather, rain, and snow. But now the area where that forest lives gets hotter temperatures, less rain, less snow than it used to. Maybe a different ecosystem, like an oak forest, or chaparral, or grassland might thrive in that area, but it’s occupied by a conifer forest that dates from a time when the climate was different.
Past a certain point of change, the conifer forest become stressed to the point where trees get sick, they get vulnerable to pests, they die. Then a wildfire sweeps through and cleans out that dead or dying ecosystem. Most likely a lot of these places that have been burned over in recent years will be replaced by something different, but it might take generations before a stable, healthy, rich, and complex ecosystem forms again. No doubt, species will go extinct during the process. Plus it’s going to be hell on us humans watching the familiar places burn and choking on the smoke for years as it plays out.
