The chemtrail conspiracy theory posits that some trails left by aircraft are chemical or biological agents deliberately sprayed at high altitudes for purposes undisclosed to the general public and directed by various government officials.[1] This theory is not accepted by the scientific community, which states that they are just normal contrails, as there is no scientific evidence supporting the chemtrail theory.
Because of the popularity of the conspiracy theory, official agencies have received thousands of complaints from people who have demanded an explanation.[1][2] The existence of chemtrails has been repeatedly denied by scientists and government officials around the world, who say the trails are normal contrails.[3]
The term chemtrail is a portmanteau of the words "chemical" and "trail," just as contrail is a contraction of "condensation trail." The term does not refer to other forms of aerial spraying such as agricultural spraying ('crop dusting'), cloud seeding, skywriting, or aerial firefighting.[4] The term specifically refers to aerial trails allegedly caused by the systematic high-altitude release of chemical substances not found in ordinary contrails, resulting in the appearance of characteristic sky tracks. Supporters of this conspiracy theory speculate that the purpose of the chemical release may be for solar radiation management, psychological manipulation, human population control,[1] weather modification,[2] or biological or chemical warfare, and that these trails are causing respiratory illnesses and other health problems.[5][6]
Overview

In 1996, a chemtrail conspiracy theory began to circulate when the United States Air Force (USAF) was accused of "spraying the US population with mysterious substances" from aircraft "generating unusual contrail patterns."[7] The Air Force says these accusations were a hoax fueled in part by citations to a strategy paper drafted within the Air Force's Air University entitled Weather as a Force Multiplier: Owning the Weather in 2025.[8][9] The paper was presented in response to a military directive to outline a future strategic weather modification system for the purpose of maintaining the United States' military dominance in the year 2025, and identified as "fictional representations of future situations/scenarios."[9] The Air Force further clarified that the paper "does not reflect current military policy, practice, or capability," and that it is "not conducting any weather modification experiments or programs and has no plans to do so in the future."[7][10] Additionally, the Air Force states that the "'Chemtrail' hoax has been investigated and refuted by many established and accredited universities, scientific organizations, and major media publications."[7]
In Britain, when the Secretary of State for Environment, Food and Rural Affairs was asked "what research her Department has undertaken into the polluting effects of chemtrails for aircraft", the response was that "the Department is not researching into chemtrails from aircraft as they are not scientifically recognised phenomena," and that work was being conducted to understand "how contrails are formed and what effects they have on the atmosphere."[11]

In a response to a petition by concerned Canadian citizens regarding "chemicals used in aerial sprayings are adversely affecting the health of Canadians," the Government House Leader responded by stating, "There is no substantiated evidence, scientific or otherwise, to support the allegation that there is high altitude spraying conducted in Canadian airspace. The term 'chemtrails' is a popularised expression, and there is no scientific evidence to support their existence."[12][13][14][15] The house leader goes on to say that "it is our belief that the petitioners are seeing regular airplane condensation trails, or contrails."[12]
Various versions of the chemtrail conspiracy theory have circulated through Internet websites and radio programs.[1] In some of the accounts, the chemicals are described as barium and aluminum salts, polymer fibers, thorium, or silicon carbide.[3] In other accounts it is alleged the skies are being seeded with electrically conductive materials as part of a massive electromagnetic superweapons program based around the High Frequency Active Auroral Research Program (HAARP).[16] Those who believe in the conspiracy say the chemtrails are toxic,[17] but the reasons given by those who believe in the conspiracy vary widely, spanning from military weapons testing, chemical population control, to global warming mitigation measures.[2] Scientists and federal agencies have consistently denied that chemtrails exist, insisting the sky tracks are simply persistent contrails.[3] As the chemtrail conspiracy theory spread, federal officials were flooded with angry calls and letters.[3] A multi-agency response to dispel the rumors was published in a 2000 fact sheet by the Environmental Protection Agency (EPA), the Federal Aviation Administration (FAA), the National Aeronautics and Space Administration (NASA) and the National Oceanic and Atmospheric Administration (NOAA), a step many chemtrail believers have interpreted as further evidence of the existence of a government cover-up.[3]
Proponents of the chemtrail conspiracy theory say that chemtrails can be distinguished from contrails by their long duration, asserting that the chemtrails are those trails left by aircraft that persist for as much as a half day or transform into cirrus-like clouds.[2]
In 2001, US Congressman Dennis Kucinich introduced H.R. 2977 (107th) Space Preservation Act of 2001 that would have permanently prohibited the basing of weapons in space, listing chemtrails as one of a number of "exotic weapons" that would be banned."[18][19][20] Proponents have interpreted this explicit reference to chemtrails as official government acknowledgment of their existence.[21][22] Skeptics note that the bill in question also mentions "extraterrestrial weapons" and "environmental, climate, or tectonic weapons."[23] The bill received an unfavorable evaluation from the United States Department of Defense and died in committee,[24] with no mention of chemtrails appearing in the text of any of the three subsequent failed attempts by Kucinich to enact a Space Preservation Act.
Contrails vs chemtrails

Contrails, or condensation trails, are "streaks of condensed water vapor created in the air by an airplane or rocket at high altitudes."[7] These condensation trails are the result of normal emissions of water vapor from piston engines and jet engines at high altitudes in which the water vapor condenses into a visible cloud. Contrails are formed when hot humid air from the engines mixes with the colder surrounding air. The rate at which contrails dissipate is entirely dependent on weather conditions and altitude. If the atmosphere is near saturation, the contrail may exist for some time. Conversely, if the atmosphere is dry, the contrail will dissipate quickly.[7]

It is well established by atmospheric scientists that contrails can not only persist for hours, but it is a perfectly normal characteristic for them to spread out into cirrus sheets. The different sized ice crystals in contrails descend at different rates, which spreads the contrail vertically. Then the differential in wind speeds between altitudes (wind shear) results in the spreading of the contrail across many miles in the sky. This mechanism is similar to the formation of cirrus uncinus clouds. Contrails between 25,000 and 40,000 feet can often merge into an "almost solid" interlaced sheet.[25] Contrails can have a lateral spread of several kilometers, and given sufficient air traffic it is possible for contrails to create an entirely overcast sky which increases the ice budget of individual contrails and persists for hours.[26]
![](http://upload.wikimedia.org/wikipedia/commons/thumb/1/1a/Contrails_formed_at_high_altitude.png/220px-Contrails_formed_at_high_altitude.png)
The term "chemtrails", coming from the words "chemical trails" in the same fashion that the term "contrail" comes from the words "condensation trail," is a term coined to suggest that contrails are formed by something other than a natural process of engine exhaust hitting the cold air in the atmosphere. Proponents of the theory of the existence of chemtrails characterize these phenomena as streams that persist for hours and that, with their criss-cross, grid-like or parallel stripe patterns, eventually blend to form large clouds. Proponents view the presence of visible color spectra in the streams, unusual concentrations of sky tracks in a single area, or lingering tracks left by unmarked or military airplanes flying at atypical altitudes or locations as markers of chemtrails.[1][3][5][21][27][28]

Experts on atmospheric phenomena deny the existence of chemtrails, asserting that the characteristics attributed to them are simply features of contrails responding differently in diverse conditions in terms of the sunlight, temperature, horizontal and vertical wind shear, and humidity levels present at the aircraft's altitude.[1][3][5][7][21] Experts explain that, in the United States, what appear as patterns such as grids formed by contrails result from increased air traffic traveling through the gridlike U.S. National Airspace System's north-south and east-west oriented flight lanes, and that it is difficult for observers to judge the differences in altitudes between these contrails from the ground.[7] The jointly published fact sheet produced by NASA, the EPA, the FAA, and NOAA in 2000 in response to alarms over chemtrails details the science of contrail formation, and outlines both the known and potential impacts contrails have on temperature and climate.[10] The USAF produced a fact sheet as well that described these contrail phenomena as observed and analyzed since at least 1953. It also rebutted chemtrail theories more directly by identifying the theories as a hoax and denying the existence of chemtrails.[3][7]
Patrick Minnis, an atmospheric scientist with NASA's Langley Research Center in Hampton, Virginia, is quoted in USA Today as saying that logic does not dissuade most chemtrail proponents: "If you try to pin these people down and refute things, it's, 'Well, you're just part of the conspiracy'," he said.[1]
Analysis of the use of commercial aircraft tracks for climate engineering have shown them to be generally unsuitable.[29]
What are often called contrails are more often than not in fact the visible manifestation of some yet-to-be-identified liquid or power chemical substance being injected INTO to the exhaust plume emanating from each of the airplane turbojet engines, to which phenomenon the term "chemtrail" would be more appropriate, as opposed to the rarer "contrail" phenomenon which is the result of H2O vapor (always found as a combustion product in jet-engine exhaust) condensing in the ambient air. This nefarious process by which chemicals are introduced into the airplane exhaust plume is frequently achieved by means of injectors surreptitiously installed in obscure positions immediately behind each engine. Such an installation can fairly safely be assumed to have been carried out subsequent to the manufacture of the airplane, carried out in order to give the illusion to e.g. airplane spotters and others watching from a distance that the visible trail is produced by the products of combustion inside the engine. This is be a deliberate deception typical of various deceptions conducted under the extreme secrecy in which the topic of chemtrail production is shrouded.

Photographs of barrels installed in the passenger space of an aircraft for flight test purposes have been claimed to show aerosol dispersion systems. The real purpose of the barrels is to simulate the weight of passengers or cargo. The barrels are filled with water, and the water can be pumped from barrel to barrel in order to test different centers of gravity while the aircraft is in flight.[31]
