Not one of the three articles you posted supports climate change as the root cause of anything, including the frequency of events. They all do resort to the "Thor is angry at us" method of ascribing causality where it does not exist. Why? Because, if you are a researcher the money keeps flowing as long as you support the cult. Any researcher who dares question this can look forward to driving for Uber. This cult has become a powerful political tool, and science has been distorted because of it.
Notes (quotes from articles you posted):
"How has only 11 percent of the west burned, yet the annual number of acres burned and the frequency of fire increased? It turns out that many fires are occurring in areas that have already experienced fires, known as burn-on-burn effects. About 3 percent—almost a third of the burned land—has seen repeated fire activity."
Interesting, isn't it. THE WORLD IS ON FIRE! THE WORLD IS ON FIRE! FIRES ARE HAPPENING MORE OFTEN!
Wait. Wait. What's going on? Only 11% has burned and a third of that is the same areas burning? Well, first, this does not look like the end of the world at all. This hints at other reasons. What are they?
Well, as is usually the case, none of these papers discuss or explore other potential drivers in detail. It's climate change. Kneel, bow down and accept everything we tell you to think and do.
OK, so, a few of us like to actually think. How about this:
https://www.statista.com/statistics/206097/resident-populati...
Population of California has gone from about 15 million to 40 million since 1960. Surely that had nothing to do with it. Right? What is the probability of more homes, vehicles, power lines, power consumption and accidents increasing any kind of event when the population of a region quadruples in size?
No, sorry, it's climate change. How dare I suggest that more people occupying a region might lead to more of anything. How dare I suggest that mismanagement and bad governance might actually be part of the problem.
Here's another fun one:
https://www.statista.com/statistics/1067138/population-unite...
Population of the US went from 80 million in 1900 to over 300 million today. Yet, everything is caused by climate change. Everything. Well, that's what one of the articles clearly states anyway:
“But because the root cause is climate change, the most important path forward is to prevent further degradation and warming, which requires both individual and collective action.”
Once again, kneel down and submit. It's climate change, not a 4x population growth and everything that comes with it.
Well, at least one of the articles takes a glancing pass at this, while neglecting to mention population quadrupled:
"In the Western U.S., people are accidentally igniting fires all the time"
Four times more people folks. Does it stand to reason that you might have an increase of incidents that might lead to large fires? Nah, climate change.
"For example, in 2018 sparks flying from hammering a concrete stake into the ground in 100-degree Fahrenheit heat and sparks from a car's tire rim scraping against the asphalt after a flat tire were the causes of California's devastatingly destructive Ranch and Carr Fires, respectively"
Four times the population has no impact on the occurrence rate of potential fire-starting events?
Anyhow, this is why I react badly to the climate change card constantly being pulled out as the root cause of absolutely everything. The domain has become polluted with bad science and politics. It is dishonest and likely damaging to society. From my perspective it seems very difficult to list it as the root cause because almost 100% of the time people neglect to include a million other variables in the conversation.
Be careful with buying into a cult. Human sacrifices were justified with such things.
