Chemtrails are used to steer and propagate energies used in
ultra-secure communications, and because they quickly lose their
coherency, chemtrails that is, to become reflective layers of clouds
over a few hours time, they can also be (are) used to form what must be
called "The Broadcast Canopy", a major tool within the radiant arsenal
and in weather modification. A huge reflective sheet is formed over a
subject population, and the energies and frequencies broadcast from
antennae farms everywhere can be attuned to achieve ends that have been
researched extensively by the CIA during Projects Paperclip, MK-ULTRA,
and others...

Broadcast Canopys also are used to perpetuate things like through-wall
radar, very long distance sound bugging of premises, computer monitoring
from afar, and general invasions of privacy...

Contrail-like cloud left by aircraft believed by "spiritual" people to contain chemicals or crystals. These chemtrails are allegedly part of a secret government program either to save earth from global warming or to kill off half of humanity.

The means by which the Illuminati sprays its proverbial load.

A nickname for contrail clouds left behind by planes that refers to a theory. It is believed that these contrails serve as pollution, reducing the earth surface's exposure to sunlight. This causes global cooling.

The theory though, is that there was and possibly stil is a government conspiracy, in which they are flying military planes that purposely create these chemtrails to cause global cooling (slowing down or lessening the effects of global warming).

bullshit conspiracy theory.
