This is one of the best posts I've yet seen about weather modification and geoengineering. I knew of some of these declassified programs, but not all of them. What I think is important to stress is that correlation is not causation. When we see something strange we can't explain, our primitive minds really enjoy jumping to conclusions, creating stories, and (in some cases) inventing a cause even if we don't have enough information to reliably do so.
It's unfortunate how many people enjoy a good conspiracy theory at the expense of reality. They promote claims which can sometimes be provably shown as false or at least logically inconsistent. That's what I appreciate so much about this post. You took an often misunderstood and miscommunicated (IMO) topic and used historical evidence and reliable sources to explain it.
That said, proof that weather modification programs have happened in the past does not automatically prove the weird things we see in the sky are, in fact, the same thing (or some future version of it). This is where things get tricky. I've yet to meet someone who believes strongly in widespread chemtrail programs who can reliably tell the difference between contrails and chemtrails. For example, when we see patterns in the sky similar to your image, is the assumption that, during that window, every single commercial airliner in that space at that time is participating in the spraying? I've seen some planes without a trail while those patterns were visible, but those planes were clearly at a much different altitude and from what I've researched, contrails form based on atmospheric conditions which can vary widely based on things like altitude.
I don't intend to debunk what you've posted here because, again, I respect the approach you've taken to be factual and keep your assumptions to a minimum. I just hope we can be careful about jumping to conclusions based on incomplete evidence. As an example, I still occasionally see people talking about how HAARP is causing all this, without realizing it has been shut down for years. Epistemology is key. We have to have good mechanisms for understanding what real knowledge is and too often people who get stuck in rabbit holes of unproven claims fall into the trap of confirmation bias towards their already assumed position (including me!).
I hope more information becomes available on what is really going on so we can separate the facts from the fiction. Thanks again for writing such a great post on the topic.
