I believe some of the anti climate science movement is part of a generalized attack on authority in all its forms. I'm most familiar with this trend in the subject area of American history. The History Network, principally through its offering "America Unearthed", and through the theories of that program's principle protagonist, a geologist whose specialty is the forensics of concrete, not History, has promoted the notion, which first appeared in sensationalized and fictionalized stories of 19th century newspapers trying to outsell one another, that the Smithsonian Institution has engaged in a systematic repression of the truths of American prehistory. Nothing could be further from the truth, but that does not stop those who would attack authority in all areas of knowledge from supporting this fiction. So, this attack on authority in the subject of history is in a similar vein to attacks on science as a source of authority pertaining to our knowledge of the natural world. Whether one is dealing with politics, the social sciences, or the hard sciences, attack on authority as elites trying to pull the wool over the eyes of non specialists has been on the rise for awhile now.
Seen as an upwelling of irrational thought, not the first time in Western cultural history, it becomes very difficult to accept at face value, since the entire aim seems to be the simple undermining of authority, and not the creation of viable theories or interpretations that deal with actual facts. If it simply pushes the narrative "the experts are wrong, and they may even be trying to deceive the public", the public feels empowered. And, right now, that narrative really sells, as the public, significant numbers of the public, have arrived at a position of fundamental distrust of authority in all its forms.
Rejection of authority for its own sake is irrational, and is a nihilistic mindset that replaces knowledge with ignorance. Pretty hard to put any faith or trust into such a movement. There's a reason both hard scientists and social scientists undergo training in their respective disciplines. The reaction against these authorities in the modern era is an effort to claim untrained and uneducated members of the public are qualified to overturn the received wisdom of the day and replace it with poorly reasoned, and often conspiracy-tinged, alternatives. It's BS, but it's very potent BS, because it is doing a very good job undermining confidence in science among the public. It's pop science, pop history, pop archaeology. It does not adhere to tough standards where evidence and logical argument is concerned. The uneducated would bring the educated down to their level. Next, we will see a movement to allow anybody off the street to perform brain surgery. Surgeons are simply another elite. If America is a late stage democracy where an unqualified reality TV star can get elected President, the same attitude that even rank amateurs can overturn historical narratives with no formal training, and poor use of facts, is also very much holding sway where our bodies of learning are concerned.
The barbarians are at the gates. And they battered their way through the gates some time ago. They would elevate the ignorance of the uneducated and promote ignorance at every turn. Now they have an anti-science President, a devotee of conspiracy theory, to lead the way.
