What Is Weather Modification?

Cloud seeding is the primary weather modification activity. Cloud seeding is the process of burning silver iodide through an ice nucleus generator that is carried up into the clouds to stimulate the precipitation process. There are many types of weather modification, including ground-based snowpack augmentation, airplane-based snowpack augmentation, airplane rain augmentation, hail suppression and hail cannons.

Project Summary

In January 2014, Governor Jerry Brown proclaimed a State of Emergency throughout California due to severe drought conditions. In response to the Governor’s proclamation, the Los Angeles County Board of Supervisors directed Public Works to pursue enhancing local water supplies by reviving a cloud seeding project. On October 20, 2015, the Board Approved the County of Los Angeles Weather Modification Project and awarded a service contract for As-Needed Weather Modification (Cloud Seeding) Services to North American Weather Consultants (NAWC). This contract was for a term of 1 year, with four 1-year renewal options.

The Department of Public Works successfully cloud seeded the San Gabriel Mountains during March and April 2016. Public Works engineering staff and NAWC licensed professional meteorologists operated up to 10 land based cloud seeding generators. The operation of the cloud seeding generators depended on weather forecasts, consultant analysis, and the targeted watersheds anticipated increase in rainfall amounts. With the end of the storm season on April 15, 2016, cloud seeding operations ceased.

During the summer of 2016, the San Gabriel Complex and Sand fires burned a significant portion of the watersheds targeted by the cloud seeding project. Consequently, cloud seeding operations were not restarted and the service contract was allowed to expire. Although the application of the latest cloud seeding techniques and methodologies was a success, the Department does not currently anticipate pursuing cloud seeding operations until the project’s targeted burnt watersheds have completely recovered and replenishment of local water supplies warrant.

Is Cloud Seeding Harmful to Your Health?

Cloud seeding has been around for decades, but the general public has not known about it until recently. In 1946 it was discovered by a General Electrics lab that Silver Iodide could be used to make already existing clouds put out more rain. It was the 1950’s that this technology started to be used en force to battle drought. Since that time it is used as needed all over the world depending on the drought levels, and with the increasing water shortages worldwide, cloud seeding is becoming more and more common.

In order for cloud seeding to work, there has to be rain clouds already present. By filling the cloud with silver iodide, they can increase the rainfall by 5 to 30 percent depending on where the clouds are located. It’s easier to make more rain from a cloud near the coast as opposed to inland.

Today, companies like the North American Weather Consultants, Inc create and set up cloud seeding stations that are portable and easy to transport so they can get them where they are needed most. In Los Angeles there are currently 10 towers set up between Sylmar and Pacoima.

These portable generators shoot Silver Iodide into the already existing clouds, which bind to the water molecules creating an instant freezing of the water particles. The now heavy frozen water vapor falls from the sky as rain.

The concern over silver iodide in our water and air supply is a real one. While the studies are still being conducted around this topic, what we do know is that silver iodide is highly susceptible and when it drop and falls into our atmosphere it quickly breaks down. The US Public Health Service claims there is a negligible environmental impact by cloud seeding. That said, silver iodide when studied in labs is a different story all together and is indeed toxic and dangerous.

There are other studies showing that silver iodide is toxic especially to fish and wildlife. This particular study is quoted as stating that “repeated exposure of animals to silver might produce anemia, cardiac enlargement, growth retardation, and degenerative changes in the liver.” (Seiler, H.G., H. Sigel and A. Sigel (eds.). Handbook on toxicity of inorganic compounds. New York, NY: Marcel Dekker, Inc. 1988. 622).

Ecological effects of silver iodide and other weather modification agents 

The silver ion is among the most toxic of heavy metal ions, particularly to microorganisms and to fish. The ease with which Ag forms insoluble compounds, however, reduces its importance as an environmental contaminant. Ag is not likely to concentrate to harmful levels through either terrestrial or aquatic food chains. There is some possibility that Ag from cloud seeding will retard growth of algae, fungi, bacteria, and fish in fresh water, wild animals, etc. Inhibition of aquatic microorganisms would interfere with the cycle that returns essential nutrients to the water. Ag in air and water should be regularly monitored. Iodine in AgI poses no environmental danger. Organic seeding agents currently being proposed are not likely to be toxic in either the short or the long run, but dispersal of proprietary organic compounds should be prohibited unless their composition is fully revealed.

Tracers – Clouds and Trails | NASA

First used with sounding rockets flown in the 1950’s, scientific research with experiments which inject vapor tracers in the upper atmosphere have greatly aided our understanding of our planet’s near-space environment. These materials make visible the naturally occurring flows of ionized and neutral particles either by luminescing at distinct wavelengths in the visible and infrared part of the spectrum or by scattering sunlight.

The type of vapor selected to create these colorful clouds and trails depends on the purpose of the investigation, the local time, and the altitude under study. Commonly used vapors that are released in space are:

  • Tri-methyl aluminum (TMA),
  • Lithium, and
  • Barium.

Tri-methyl aluminum (TMA)

Trimethyl Aluminum reacts with oxygen and produces chemi-luminescence when exposed to the atmosphere. The products of the reaction are aluminum oxide, carbon dioxide, and water vapor, which also occur naturally in the atmosphere. TMA releases are most often used to study the neutral winds in the lower ionosphere at night at altitudes of 100 miles (160 kilometers) or less.

Lithium vapor is also used to study neutral winds in the upper atmosphere. Lithium gas has an unusually bright narrow-band emission at 670.7 nanometers, a wavelength in the infrared range, which enables it to be visible in the daytime with cameras with infrared filters. In fact, Lithium is the only vapor that can be imaged during the day and is also one of the few vapors that can be used at high altitudes (> 124 miles or 200 kilometers) at night. At night, its color is bright red.


Barium  is used to study the motion of both ions and neutrals in space. A fraction of a barium cloud ionizes quickly when exposed to sunlight and has a purple-red color. Its motions can be used to track the motion of the charged particles in the ionosphere. The remainder of the barium release is neutral, having a different color, and can be used to track the motion of the neutral particles in the upper atmosphere.

The cloud in the upper left hand part of the image is due to a barium release. The purple-red part is the ionized component which has become elongated along the Earth’s magnetic field lines. The purple-blue cloud that surrounds the red ionized barium is a combination of the neutral barium and strontium. The blue and white trail in the lower portion of the image is from a TMA vapor trail that reveals the neutral wind trails as a function of altitude. Credits: NASA

A small quantity of strontium or lithium is sometimes added to the barium mixture to enhance the neutral barium emissions, making it easier to track the neutral cloud. Since the observer must be in darkness while the barium cloud is in sunlight, the technique is limited to local time observations near sunset or sunrise.














The film is called ‘Skywatcher: The Incredible Story of Artificial Clouds and Weather Modification’, it’s shocking, very interesting and well worth watching.


Climatologists vastly underestimate the amount of deliberate weather modification programs, erroneously believing them to be occasional “experiments,” and unaware that THOUSANDS of planned weather modification events occur every year in the U.S. and worldwide. So let’s get our facts straight: Weather Modification programs are not isolated, low-altitude events; they are prolific, ongoing high-altitude programs in an industry that has been growing since the 1960s.

It is NOT solar radiation management (SRM) that we are witnessing when we see “chemtrails” and artificial clouds created by aircraft; it is PRECIPITATION ENHANCEMENT, designed to thicken clouds to produce more rain and snow through cloud seeding. (But we cannot change the weather significantly without changing the “climate” too. Climate Change = weather change over time.) ====✈ CONTRAILS persist and form clouds when enough cloud condensation nuclei (CCN) are present at the right altitude.

Most people are unaware that CCNs are deliberately dispersed via cloud-seeding flares ABOVE AND IN FRONT OF incoming storm clouds, regularly, in most developed counties and in at least 68 US counties. The flares are burned right at the altitude where contrails are formed, ~20,000 feet (cloud seeding pilots interviewed stated 5,000 to 40,000 feet, most commonly 16-22,000 feet.) Contrails do not usually form at low altitudes or very high altitudes, and they almost always have a starting and stopping point– the range in which sufficiently abundant CCNs are present. This range is also where aircraft accelerate the most as they climb to cruising altitude, creating the most water vapor. The vapor instantly freezes to form ice crystals which expand in the low-pressure environment and bond with other CCNs present, which can form thick clouds and sometimes even create total cloud cover IN FRONT OF STORMS– before the storm clouds even arrive. This effect causes the formation of artificial clouds in perfectly blue skies, and the appearance that jet aircraft are “spraying something” when, actually, they are spraying super-heated water vapor, which becomes expanding frozen water particles.

The invisible, cloud nuclei containing metallic aerosols were dispersed previously, bonding with the ice crystals and thus facilitating the cloud formation process. In other words, SMALL AIRCRAFT disperse cloud seeding material into the sky, and then LARGE JETS pass through it, and their condensation vapor (C02 + H2O) bonds with with those materials to form the thick, persistent contrails. (See the time-lapse sequences starting halfway through the video.)

*** FACT: Cloud seeding flares contain metallic aerosols known to be toxic to humans, including silver iodide, aluminum, strontium, and magnesium.

These aerosols do not simply “fall”… the invisible clouds of CCNs expand and go WHEREVER THE WIND GOES before eventually bonding with ice crystals or drifting slowly down into our soil, water, and lungs. . . . This video shows exactly HOW we make clouds with aircraft, why the jet contrails persist now (when they used to disappear much more quickly), and why we’re finding high levels of metals in our water and soil, including aluminum and strontium. …you sure you want the truth?

Silver Iodide falling from Colorado sky

Silver iodide falling from sky in Colorado. In 1960 Colorado started their cloud seeding program. It looks like silver glitter falling, and zero precipitation today. And snow leaves wet spots. I even picked some up on my finger, and its a metal shaving and reflects light. http://cwcb.state.co.us/water-managem…

So chemtrails are real, and there’s a link. Nevada, Arizona, Colorado, California has been doing cloud seeding since 1960s Here in Colorado most ski resorts fund cloud seeding. Generate more state revenue threw tourism. But it absorbs percipitation in atmosphere and steals water from local farm land making Colorado prairies dry land killing agricultural land. San Luis Valley use to be a green farmland and now its dry land.
