Of all the subjects I have researched, the Chemtrail issue has always been met with the most skepticism: I’ve been scoffed at more times than I care to remember.

What frustrates me the most is how blatantly obvious the program’s existence is.

If you were to go outside and peer up at the sky, chances are you would see the proof of the spraying campaign with your own eyes. I myself observe the phenomenon almost every day, and often point the Chemtrails out to those I am with.

Despite the fact that the proof is right in front of their eyes, most people dismiss the suggestion as unsubstantial. In order to get them to even consider the existence of Chemtrails, it usually takes a hefty volume of documented proof. This is not a particularly difficult task, as there is such a large body of evidence that not only proves Chemtrails exist, but also that the practice has had devastating effects on the environment and public health.

In hopes of spreading awareness about this issue, I have compiled an extensive list of patents that outline the technology and methods of Stratospheric Aerosol Geoengneering (Chemtrails). Some of these patents date back to the 1920s, which indicates the program has been in the works for decades.

Out of all the patents I’ve collected, one stands out among the rest:

5003186- March 26, 1991

Stratospheric Welsbach Seeding for the Reduction of Global Warming

This process and technology is the closest model the public has for explaining the Chemtrail phenomenon, but it is far from the only documentation to do so. Below is a comprehensive list of patents that prove the existence of the Chemtrail spraying program.

Originally the list I was intending to publish was 80+ patents long, but the Hubpages mechanics would not allow me to use the whole list. Apparently, a similar collection of patents can be found on other Hubs or websites, and therefore I am not allowed to include it in its entirety.

In light of this issue, I have selected (what I believe to be) the most significant patents dealing with the Chemtrail process.
