Frequently Used Terminology

[Read More:]

Chemical-Trail. A trail containing chemical and/or metal particulates.

Modern usage refers to man-made trails in the atmosphere which are by aircraft. Although there is a variety of methods available to disperse atmospheric chemical trails e.g. rockets, ground-based deployment technologies, ships.

Chemtrails can contain metal and chemical particulates including: Sulfur, Carbon Black. Aromatics, Aluminium etc. Such substances cause/contribute to aviation induced cloudiness and often referred to as ‘Cloud Condensation Nuclei’ or CCN’s.

The word ‘chemtrails’ is often used interchangeably with and/or can refer to: Weather Modification, Cloud Seeding, Geoengineering, Solar Radiation Management (SRM), Stratospheric Aerosol Injection (SAI), Climate Engineering, Persistent Contrail, Aviation Induced Cloudiness, Marine Cloud Brightening (MCB), Sky Whitening and Weather Warfare.

Atmospheric Convection Management (ACM)
Management of earth’s convection processes. Convection is a process which acts to transport much of earth’s surface heat to the upper troposphere and is linked to earth’s atmospheric circulation and climate systems.

Albedo Modification
Modification of earth’s reflectivity (albedo); with high albedo meaning bright, and low albedo meaning dark.

Aviation Induced Cloudiness (AIC)
aka Induced Cirrus Cloudiness, Artificial Clouds, Man-Made Cloud, Aviaticus Cloud.

Carbon Dioxide Removal (CDR)
The deliberate removal of carbon dioxide from earths’ atmosphere. This technology also involves a Carbon Dioxide Storage and/or Recycling component.

Condensation trail created by aircraft.

Persistent Contrail (aka Aerodynamic contrail)
A persisting contrail which forms man-made high-altitude cirrus clouds, or high thin cirrus clouds which have been found to trap heat.

Young Contrail
A contrail less than 5 hours old.

Contrail Cirrus (aka High Thin Cirrus)
A contrail that has formed into a cirrus cloud. Known to trap heat.

Climate Engineering/Intervention
The deliberate and large-scale engineering/intervention in the Earth’s climatic system.

Cloud Brightening (aka Marine Cloud Brightening, MCB)
Introducing sea water particles (as little as 2 µm in diameter) to increase cloud reflectivity (albedo), making clouds brighter.

Environmental Modification (EnMod)
EnMod also refers to an international 1978 UN treaty, prohibiting the hostile use of environmental modification technologies. See the Environmental Modification Convention (, aka the Convention on the Prohibition of Military or Any Other Hostile Use of Environmental Modification Techniques.

Earth Radiation Management (ERM)
Management of earth’s (radiation budget) long and short-wave radiation.

The deliberate large-scale manipulation of an environmental process.

Global Dimming
A reduction in the amount of sunlight reaching earth’s surface.

High-Frequency Advanced Auroral Research Project (HAARP)
Originally a US Military funded research project, now used by academic researchers, the HAARP facility is located in Alaska and aims to research and/or enhance earth’s ionosphere, enabling better radio communications and surveillance technologies. (See also ionospheric heater).

A region of earth’s atmosphere which includes earth’s thermosphere and some of earth’s mesosphere and exosphere.

Ionospheric Heater
Technology designed to transmit strong radio waves into earth’s ionosphere and upper atmosphere, modifying electron temperatures, to research plasma turbulence.

Update: Groups, Membership and Community Project.

Hi all,

We hope this finds you well. Just a quick update.

1. After much debate it has been decided to remove the groups function from the site; this also means memberships will be automatically cancelled as registrations were done through the groups app. We are hoping to have an option for membership again in the future, but as the groups have remained unused by members, this function will not be reconsidered in the foreseeable future. We appreciate all of those who did become registered members of the site and hope you re-join when the membership option becomes available again (Effective as of June 25 2019).

2. The community (video) project has been cancelled due to lack of interest and/or content.

We apologise for any inconvenience these changes may cause.

Geoengineering: Psychology and Framing

A Chapter from the OpChemtrails Information Booklet

The Royal Society in the 2010 document titled “Experiment Earth? Report on a Public Dialogue on Geoengineering “asserts that “public attitudes towards geoengineering should be a critical factor in considering the future of geoengineering.” It is well known that agencies have been perfecting ways to manipulate the public for some decades; incidents such as the Gulf of Tonkin preceding the Vietnamese War, the Nayirah testimony and programs such as Operation Mockingbird only further demonstrate a willingness to induce the general public.

Documentation detailing ways to better understand (and therefore control) public perception of geoengineering proposals are well recognised; including discussions, forums, information gathering, and networking between key stakeholders, all to determine the soundest ways to frame geoengineering programs when it finally comes time to inform the general public and begin the open implementation of said programs.

The document Public understandingof solar radiation management [3.4. Conspiracy theories], details findings that include “2.6% of the subjects believe that it is completely true that the government has a secret program that uses airplanes to put harmful chemicals into the air, and 14% of the sample believes that this is partly true.” “Conspiracy Theory” is a disparaging term used to vilify and ridicule the very people it is used to describe. By examining responses to different terminology and by using focused terminology in documentation they are “no longer lucidly [expressing] the nature of things, but rather [obscuring] and [distorting] them” (Chilton, 2); below is another example of this, taken from the same document [4. Discussion].

The word supporter has a positive connotation, whilst the word detractor has a negative connotation; when you search both words often (as below) supporters and shown in green and detractors in red.

Ultimately this conveys the message that supporters of geoengineering are more agreeable and those against or critical of geoengineering are defiant. This is further demonstrated when looking at the Cambridge Dictionary: synonyms, related words and phrases.

Nobody wants to be seen as opposition and many studies have determined that human beings do not like to be singled out, ostracized or socially rejected, this is a key component used to sway public opinion on the topic. Being labelled a conspiracy theorist or a ‘detractor’ will almost certainly influence whether or not people object to or consent to geoengineering.

What They Want to Know 
  • How widespread is public knowledge of geoengineering and SRM? 
  • How does the public perceive geoengineering and SRM? 
  • How the seriousness of climate change affects individuals views on geoengineering? 
  • What are key areas of concern, perceived trade-offs and risks (table 5 below)? I.e. what is the public more willing to accept. 
  • The role/opinions of specific groups/communities i.e. environmentalists, economists, media.

Beware the Geoengineering Salesman

Things we are hearing and seeing that show they are testing the waters with regards to public response include:

Sales pitch: Geoengineering may be one possible response to climate change.

What They Really Mean: They’re going to emit/spray us with chemical & metal particulates to save us [example: To Fix Climate Change, Scientists Turn To Hacking The Earth]

Sales pitch: Using media and imagery to depict apocalyptic version of climate change.

What They Really Mean: We need to geoengineer the planet or we are all going to die [example: COP21: Can we avoid climate apocalypse?]

Sales pitch: Saying that it is accidental rather than intentional.

What They Really Mean: Oops we didn’t realise it was happening [plausible deniability] [example: Airplane Contrails May Be Creating Accidental Geoengineering]

Sales pitch: Because YOU won’t change YOUR ways and YOU pollute the planet with Co2 we have to geoengineer the planet to save it.

What They Really Mean: We are just going to ignore the fact that aviation is having a detrimental and largely ignored impact on climate and weather systems and it is not adequately represented in any of our climate models [example: As the effects of global warming begin to frighten us, geoengineering will come to dominate global politics]

Definition of disinformation
: false information deliberately and often covertly spread (as by the planting of rumours) in order to influence public opinion or obscure the truth

One aspect of Geoengineering Activism that many people don’t realize and that we would like to highlight is Disinformation; both the amount of disinformation and the sheer number of disinformationists (aka trolls, shills) that dedicate untold hours to harassing activists, posting hoax information, and promoting disinformation, is astounding.

Many of the sites below have been created by people who have a long term, thorough understanding of the ‘Good, Bad & Ugly’ side of Geoengineering Activism; we highly recommend visiting these sites to gain a better understanding of:
– how disinformationists work,
– who they are,
– why they do what they do, and
– how to best deal with disinformationists when confronted by one.

Harvard Science = Mad Sciene

The thing that many people do not realize is not only have they already been geoengineering the atmosphere for decades, but they have also been researching how to best market this to the public. As briefly discussed in the chapter ‘Psychology and Framing‘ (from the OpChemtrails Information Booklet), they have held many talks, meetings, surveys, panels etc to gauge how best to sway public perception and/or concerns about dumping tonnes of toxic substances into the atmosphere.

For how long will academia, media, politicians continue making excuses? When will their constant state of ignorance and denial stop? What tactics we have seen from the geoengineering establishment so far.

Denial – its not happening, people are just imagining things
Ridicule – its just a crazy conspiracy
Its accidental – oops it was an accident
Silence – if we ignore the publics concerns they’ll just go away
Intimidation & Censorship – gag orders on environmental monitoring agences, censorship of hashtags and social media accounts
Word Play – let’s keep changing the terminology and jargon to confuse people further
Climate Change Saviours – even though we don’t know the true state of the climate, let’s tell the public that by polluting the atmosphere we can prevent climate catastrophe
To Save Humanity – we want to poison the air you breath to save you
It’s cheap and easy – just no! Anyone who believes this has failed to see the big picture.

Scariest of all is the small group of people driving this grand plan. Even they admit this will potentially be harmful to humans and the environment, however, they rationalize it by proclaiming that to not understand the science is ignorant, and that we need to understand the science ‘in case’ we are forced to use it. However, many people will argue this rational is exactly what gave us the atom bomb, biological terrorism and so on. This technology has the potential to cause global disruption to natural weather and climate systems, food sources, water sources and viable land, which will inevitably lead to global conflicts and power struggles.

As this Harvard experiment will potentially affect Mexico, the notion of accountability and governance becomes even more important. This technology indiscriminately crosses boarders, so the complexity of regulation and administration alone will take decades to hash out and finalize. The scientists know this, yet, they continue with their crazy plans in haste, so blinded by personal beliefs that they have wrongly convinced themselves they are doing the right thing (just like the scientists who made the abomb).

While the public, academia, media, and politicians debate the ifs and whens and hows of ‘future’ geoengineering programs, we are left with a sky that is already under direct assault by these white coat criminals. And, by Harvard Science portraying this as the first, large scale, outdoors geoengineering experiment they are intentionally averting public attention from the fact our sky is already laden with metals and chemicals directly linked to both military and commercial aircraft. Furthermore, given Trumps attitude towards ‘climate change’, one must wonder why on earth he would allow this experiment to take place?

How much money is being put into our species adapting to the climate rather than trying to control it? Is this even about the climate, or is it more about control? After all, he who controls the weather controls the world.

When you read the articles below, please keep in mind, the people advocating geoengineering technology have been studying public reaction and perception surrounding geoengineering for years. They know how to market things in a way that makes them seem appealing, even essential. And they know how to quell the publics very realistic fears.
