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.

Definition: Chemtrail


A trail(s) containing chemical and metal particulates.

Modern usage refers to man-made trails in the atmosphere left by aircraft, however there are a variety of known methods used 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 are often referred to as ‘Cloud Condensation Nuclei’ or CCN’s.

The word ‘chemtrails’ is often used interchangeably with and/or in relation to: Weather Modification, Cloud Seeding, Geoengineering, Solar Radiation Management (SRM), Stratospheric Aerosol Injection (SAI), Climate Engineering, Persistent Contrails, Aviation Induced Cloudiness, Marine Cloud Brightening (MCB), Sky Whitening, Weather Modification, Man-Made Clouds.

Raising Awareness Using Digital Media (Part 1): Hashtag Activism

It’s true, digital media or “new media” has made the world more connected and much smaller. It has also made the world less private, enabled more open dialogue and allowed for an increased awareness of the world we live it.

But, as with traditional media, digital media can be manipulated, distorted, twisted, monopolised, propagandised and even weaponised. “Fake News” has been around for as long as news itself, from Greek myths of gods and goddesses, medieval tales of witchcraft and the occult, fishermen’s tales of the one that got away, war propaganda, to historical records that generate a particular view of how the world was, and is.

Likewise, there have always been those who have used these same forms of media to promote change, raise awareness, to gain the attention of those who would otherwise look away and to inform communities about important information. Writers, anarchists, artists, musicians, campaigners, everyday people, hell, even some of those who are part of the establishment have used media in one way or another to share a message.

Here are some tips that may help you to get your message out to the wider digital community. While these tips do relate to OpChemtrails, I have tried to keep them generic so they are also relevant to other awareness campaigns.


Despite the fact that hashtags can be heavily censored, they are still an effective way of communicating information. Hashtags can be used on most social media platforms and are basically a way of filtering search results. OpChemtrails has used the #OpChemtrails hashtag on various platforms to raise awareness about geoengineering, the tag allows likeminded people to share information, images, videos etc. with other people who follow the tag (although for censored hashtags users will have to adjust their quality filters, sensitive information filters and tailored information filters, most platforms provide instructions on how to do this).

Hashtags can be expanded to cover specific topics. So for example, OpChemtrails currently uses these hashtags: #OpChemtrails, #OpCImageGallery (images and video), #OpCMediaWatch (mainstream media on geoengineering), #OpCLibrary (pdfs, articles, reports). While the #OpChemtrails hashtag is the primary #, the account also uses other tags such as: [#]geoengineering, SRM, SAI, MCB, SolarRadiationManagement, Sulfate Aerosol Injections, MarineCloudBrightening, CloudWhitening, SkyWhitening, Environment, Health etc.

Sometimes the tags are used in conjunction, other times individually, this helps to maximise the exposure of information. Using upper and lower case should not affect search results, but if you are having trouble finding information under a specific hashtag, simply run a key word search (e.g. without the ‘#’).

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.
