"evidence" of chemtrails is a tricky subject.
I use the term, although I think "persistent contrails" is more accurate and further removed from the 'tinfoil' effect.
There are sites such like carnicom.com or bariumblues that have articles from people claiming to have tested materials from chemtrails, but there is nothing to verify the legitimacy of the claims other than to run the tests yourself. I've seen "evidence" on Internet web pages about tests of rainwater and tests of air filters, but the subject IS ripe with disinfo, so its hard to know what to believe.
I've also read semi-convincing explanations that dismiss chemtrails as normal atmospheric phenomena. They might be wholly convincing if they didn't conflict with what I've seen and photographed myself.
Justdrew- forget Internet videos. Even if you saw one, would it really convince you of anything? (if the answer is yes, that's for another thread). Start watching the sky wherever you live, and see what your own eyes tell you. That's how I got sucked into the chemtrail issue. I don't know what materials are lingering in the sky, who is orchestrating it or why its being done, but my two eyes tell me something abnormal is going on.
I've watched jets fly back and forth on lazy Sunday afternoons spreading lines across the sky above rural areas that usually have no air traffic to speak of, let alone multiple planes criss-crossing back and forth in the same general airspace at the same time. I've watched the 'contrails' linger in the air and spread, turning blue sky and sunny days into a grey mass, and I've watched "scalar wave" formations appear.
It's funny, and scary really, how little attention industrial humans pay to the environment around them. Start paying attention, and if you want to disbelieve after that, go right ahead.
The last thread on this subject had some unhealthy influences, as et in arcadia ego is surely aware. I hope this one goes better.
one of my old blogs, which I no longer keep up, has some pictures. Scroll toward the bottom for a time-lapse series that illustrates it well in a post called "Grey skies in about an hour"
