“Believe none of what you hear, and half of what you see” - Ben Franklin

If you have not heard by now, or looked up at the sky in the last ten years, there is a big fuss over little white lines. Aircraft have created contrails (below) for well over 40 years, however recently these frozen pollution plumes are gaining visibility in a big way. [1], [2] The internet is buzzing with rumors of secret agendas and global depopulation schemes by devious government officials using “chemtrails” sprayed from commercial airliners. As incredulous as this claim may sound, we have attempted to find a definitive answer to the question “Why in the world are they spraying?” and the answers may shock you.

What is a Chemtrail?

  1. IMPROPER: internet slang for “chemical-trail”, referring to contrails
  2. CORRECT: (noun) the invisible exhaust particulates released from jet aircraft engines which contribute to the formation of persistent contrails (spreading, man-made clouds that cool the planet during the daytime and trap heat at night). • [3], [4], [5], [6]
The young contrails, which appear as a spring shape and sharp lines in the first image, gradually spread into cirrus clouds, which appear as bright white areas in the lower images.

So why continue to use the term chemtrail, if we are really talking about contrails? The invisible (chemtrail) exhaust plume of a commercial aircraft is filled with sulfur, soot (carbon black dust), and trace amounts of aluminum, barium, and so much more! [7], [8], [9]

Soot, carbon black dust, sulfur, and metals are cloud condensation nuclei (CCN) which saturate these man-made clouds, and in some cases may actually be increasing the contrails longevity. [7], [10]

Contrails are only visible when atmospheric conditions are right, with the latest research showing a link between contrail formation and the ISSR, or Ice Super-Saturated Region, which is a large water body in the sky. [11]

The distinction being made here is this: chemical trails are still there, harming our environment and health, even when there are no visible contrails.

  • A round trip flight from New York to Los Angeles releases as much C02 as one automobile does in an entire year.
  • On a yearly basis all air travel releases 600 million tons of carbon dioxide into the atmosphere.
  • 1 round trip flight from NY to LA = 2,000 pounds of CO2![12]
The chemical species released during the fuel combustion process in aircraft engines include carbon dioxide (CO2), water (H2O), nitrogen oxides (NOx), and sulfur oxides (SOx) along with small amounts of soot carbon (Csoot), hydrocarbons (HC), and carbon monoxide (CO), as shown in Figure 1. Once released at cruise altitudes within the upper troposphere and lower stratosphere (UT/LS), these species interact with the background atmosphere and undergo complex processes, resulting in potential climate impacts and related welfare loss as depicted in Figure 1. [13]


If you Google search “chemtrail,” you will see the very first entry is the Wikipedia article entitled “Chemtrail conspiracy theory.” The first line on that page states:
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. 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. [14]
Based on the Wikipedia article’s statement, which seems to sum up the online debate between the “chemtrail believers” and “debunkers,” we can extract the following two points of contention: Are they normal and are they deliberate?

1. Are contrails “normal”?

The answer to number one should be obvious, yet scientists and debunkers cling to their belief that contrails are “normal.”

TRUTH: A fire-breathing metal tube is boiling its way through the sky, farting out man-made clouds. There’s nothing normal about that, AT ALL. Contrails are the result of our desire to travel long distances through the air, which is not only “unnatural,” it is hurting our planet.

2. Are contrails deliberately being created?

TRUTH: There are as many organizations trying to end contrails as there are promoting the idea of creating artificial cloud cover.

There is strong evidence that the US. military has intentions to create cloud cover to defeat space-based surveillance satellites and weaponry, scientists worldwide want to create cloud cover to block sunlight and control global temperature, the aviation industry is moving to bio-fuels in an effort to avoid carbon taxes, and re-routing flights in an effort to and end contrails.

We at ClimateViewer would like to believe that what we are seeing in the skies is the result of the poor regulation of aviation fuels and their additives, not weather control efforts or collusion by nefarious entities to cull the herd. Besides, if they have been trying to kill the masses since the conspiracy started in 1997, they are failing miserably.

There is also an overwhelming amount of circumstantial evidence that other individuals ‘would like’ to use commercial airplanes to perform cloud seeding and/or geoengineering.

Geoengineering SRM seeks to block sunlight and cool the planet using reflective particles, however recent research is finding that contrails are not an effective method for fighting global warming. In fact, studies have shown that they are making it worse.

“the latest (June 2013) estimates indicate that contrails caused by aircraft may be causing more climate warming today than all the residual CO2 emitted by aircraft” [15].
However, there are two sides to this argument:


A. Scientists saying creepy stuff:

  • “Use commuter aircraft fuels doped with aerosol generators” [16]
  • On the possibility of weather modification by aircraft contrail [17]
  • Weather Modification by Carbon Dust Absorption of Solar Energy [18]
  • “dissolved or suspended in their jet fuel and later burned with the fuel to create seeding aerosol, or (2) injected into the hot engine exhaust, which should vaporize the seeding material, allowing it to condense as aerosol in the jet contrail” [19]
  • “Options for dispersing gases from planes include the addition of sulfur to the fuel, which would release the aerosol through the exhaust system of the plane, or the attachment of a nozzle to release the sulfur from its own tank within the plane, which would be the better option.” [20]
  • “The particles may be seeded by dispersal from seeding aircraft; one exemplary technique may be via the jet fuel as suggested by prior work regarding the metallic particles. Once the tiny particles have been dispersed into the atmosphere, the particles may remain in suspension for up to one year.” [21]
  • “regulation to ban bunker fuel for ships should be relaxed while encouraging continued use of bunker fuel where the resulting aerosol emissions might be beneficial.” [22]
  • Establish the positive and negative net forcing from contrails, and encourage flight paths of commercial airplanes to reduce positive or increase negative net forcing. The ban on polar flights, lifted recently, should be reintroduced” [22]
  • “Develop and test the deployment of suitably reflective particles, of such materials as TiO2, as alternative or supplement to sulphate aerosol.” Prepare for large scale deployment.
  • “Finance the development of, and deployment capability for, marine cloud brightening, with a view to deployment on a large scale in spring 2013” [22]
  • “Suitable chemicals need to be identified/confirmed, with stock-piling of these cloud seeding chemicals. Aircraft need to be kitted out to spray these chemicals.[22]
  • Prepare the supply and logistics for spraying aerosol precursor in large quantities, preferably into the lower stratosphere, for deployment by next March or April (2013) [22]

B. Scientists saying that creepy stuff won’t work

  • “Stratospheric passenger flights are likely an inefficient geoengineering strategy” [23]
  • “Commercial aircraft ‘not viable strategy’ for geoengineering” [24]
  • “Conspiracy theories that target specific research can have serious consequences for public health and environmental policies,” “Conspiracy theories are dangerous when the meme is used to discredit scientific evidence in a public forum or in a legal proceeding,” and “…scientists need to be careful about releasing findings on controversial issues, making sure they have been thoroughly reviewed and that the data sets are available for others to analyse” [25]
With statements like those seen in section A, one might understand why individuals would cast a wary-eye skyward, however, those are only statements, and we have found no evidence (to date) that any of these programs are currently operational. Surprisingly, neither chemtrail believers nor debunkers have considered that there is evidence the military is once again entering the world of secret weather modification.

In their Weather Modification Test Technology Symposium 1997 [26], USAF Phillips Laboratory’s Dr Arnold A Barnes Jr. gave a presentation building on the 1996 think-tank piece: “Owning the Weather in 2025” [27] where he informs us of the following:




Now why in the heck would he be talking about contrails in relation to surveillance/coverage? Here’s your answer:

“The United States needs to incorporate the defense against directed energy weapons with the same intensity used developing anti-ballistic missile defenses … ability to create localized fog or stratus cloud formations shielding critical assets against attack from energy based weapons…” [28]

You heard that right, Star Wars.

Straight from the horse’s mouth: lasers, spy satellites, and man-made clouds. Of all the plausible reasons for the aerial oddities we are seeing, this one seems the most likely. There are well-documented examples of the US. military carrying out secret aerosol programs, dispersed by plane on unsuspecting individuals, and keeping them secret for years. [29] Nonetheless, we must make use of that which we can prove lest we waste our time.

While we debate whether these contrails are normal, depopulation schemes, weather control, or satellite cover, nobody is talking about the truth:

Contrails are the poster-child for climate change, a highly-visible pollution, with massive amounts of public outrage attributed to them.

The Bottom Line:

  1. Chemtrails are invisible, contrails are filled with chemtrails, BOTH OF THESE ARE CLOUDS, the two words can be synonymous, and do not necessarily have to be associated with depopulation conspiracies.
  2. “Chemtrail conspiracy believers” and “debunkers” are not discussing the real-world implications of aviation pollution.
  3. The Geoengineers want to make clouds.
  4. The US. Air Force wants to make clouds.
  5. The Cloud-Seeders need clouds.
  6. There are man-made clouds everywhere

The next time someone tells you, they know this or that about contrails/chemtrails, tell them:

“The scientists are still scratching their heads, why are you so damn confident?” [30]:
