In the right weather conditions, long lines of thin clouds trailing planes can be seen in the sky, sometimes long after an aircraft has disappeared from view.


These clouds are contrails, and are the result of water vapour emitted from planes condensing in freezing temperatures, leaving behind “thin trails of ice crystals”, explained the Met Office.

But “ever since the US Air Force published a paper in 1996 about the hypothetical harnessing of weather for military objectives”, a “shadowy global aviation conspiracy” has spread among online communities, said National Geographic.

Theorists’ beliefs
The chemtrail conspiracy theory took root in the 1990s, but in recent years “a significant number of people” have taken to social media to share “speculation, questions and images of contrail cross-hatched skies”, said the BBC.

“Believers” say that the “puffy plumes of water vapour” that trail from planes are “evidence of a secret plot to control weather or poison the environment” by spraying chemicals into the atmosphere, the broadcaster continued.

A common claim is that the emissions from a standard plane should “dissipate quickly so any clouds that do not disappear immediately must be full of additional, undisclosed substances”, said Scientific American.

Depending on theorists' individual beliefs, “a pick-and-mix selection of the UN, the military, national governments, the Rothschilds, climate scientists, pilots and big business” are claimed to be responsible for chemtrails, said the BBC.



The reasons why a large organisation might be behind this kind of activity span a range of “nefarious purposes from weather modification, to human population control via sterilization, to even mind control”, added Scientific American.

A survey conducted in the US, Canada and UK in 2011 found that “an incredible” 16.6% of respondents subscribed to the theory, said National Geographic. A 2017 paper published in Nature found that percentage could be as high as 40% among the US general population.

Scientific response
Scientists have maintained that there is no evidence of chemical substances being atmospherically spread via planes in order to alter weather patterns, or to poison or control humans.

A common claim made by believers is that chemtrails can be distinguished from normal contrails “because they remain in the sky for longer than they did prior to the mid-90s, and dissipate into cirrus clouds”, said National Geographic.
