Scientists now admit that emissions from aircraft are forming artificial clouds that block out the sun, precisely what geoengineering advocates like top eugenicist and White House science advisor John P. Holdren have called for, but the article tries to insinuate that the effect is caused by natural “vapours,” when in reality it can be attributed to chemtrails that contain substances harmful to humans.

“The phenomenon occurs when aircraft fly above 25,000ft, where the air temperature is around minus 30C. This causes water vapour emitted by the engines to crystallise and form the familiar white streaks across the sky, known as contrails,” writes Oliver Tree for the Daily Mail.

“Reading University’s Professor Keith Shine, an expert in clouds, said that those formed by aircraft fumes could linger ‘for hours’, depriving those areas under busy flight paths, such as London and the Home Counties, of summer sunshine.”

“Experts have warned that, as a result, the amount of sunlight hitting the ground could be reduced by as much as ten per cent. Professor Shine added: “Over the busiest areas in London and the South of England, this high-level cloud could cover the sky, turning bright sunshine into hazy conditions for the entire area. I expect the effects will get worse as the volume of air traffic increases.”

The report also makes reference to a 2009 Met Office study which found that high-level winds did not disperse contrails that later formed into clouds which covered an astonishing 20,000 miles.

Of course, this is no natural phenomenon as the article claims. Ten years ago, contrails from jet aircraft disappeared within minutes, yet apparently we are led to believe that the same substance is now causing the trails to linger for hours and form into clouds. This is impossible without something within the substance having been changed.

Mainstream science and academia has gone from dismissing chemtrails as a fantasy of paranoid conspiracy theorists to now accepting that they exist but claiming that they are natural and not artificially induced.

In reality, chemtrails are the consequence of the agenda to geoengineer the earth in the name of combating climate change, a science vehemently backed by people like John P. Holdren, who in his 1977 book Ecoscience advocated poisoning the water supply to involuntarily sterilize humans as part of a “planetary regime” that would control every aspect of our existence. The fact that such eugenicists are now in control of geoengineering programs that will have a direct impact on our health is alarming.

Geoengineering programs have also been promoted by the Council on Foreign Relations, which is one of the main steering committees behind the implementation of global governance.

A recent report issued by the UK government also calls for the UN to exclusively regulate world wide geoengineering of the planet in order to stave off man made global warming.

Discussion of geoengineering technology is often framed as a future consideration, yet governments are already conducting such programs at an advanced stage.

The Atmospheric Radiation Measurement (ARM) Program was created in 1989 with funding from the U.S. Department of Energy (DOE) and is sponsored by the DOE’s Office of Science and managed by the Office of Biological and Environmental Research.

One of ARM’s programs, entitled Indirect and Semi-Direct Aerosol Campaign (ISDAC), is aimed at measuring “cloud simulations” and “aerosol retrievals”.

Another program under the Department of Energy’s Atmospheric Science Program is directed towards, “developing comprehensive understanding of the atmospheric processes that control the transport, transformation, and fate of energy related trace chemicals and particulate matter.”

The DOE website states that, “The current focus of the program is aerosol radiative forcing of climate: aerosol formation and evolution and aerosol properties that affect direct and indirect influences on climate and climate change.”

U.S. government scientists are already bombarding the skies with the acid-rain causing pollutant sulphur dioxide in an attempt to fight global warming by “geo-engineering” the planet, despite the fact that injecting aerosols into the upper atmosphere carries with it a host of both known and unknown dangers.

The proposal to disperse sulphur dioxide in an attempt to reflect sunlight was discussed in a September 2008 London Guardian article entitled, Geoengineering: The radical ideas to combat global warming, in which Ken Caldeira, a leading climate scientist based at the Carnegie Institution in Stanford, California, promoted the idea of injecting the atmosphere with aerosols.

“One approach is to insert “scatterers” into the stratosphere,” states the article. “Caldeira cites an idea to deploy jumbo jets into the upper atmosphere and deposit clouds of tiny particles there, such as sulphur dioxide. Dispersing around 1m tonnes of sulphur dioxide per year across 10m square kilometres of the atmosphere would be enough to reflect away sufficient amounts of sunlight.”

Experiments similar to Caldeira’s proposal are already being carried out by U.S. government -backed scientists, such as those at the U.S. Department of Energy’s (DOE) Savannah River National Laboratory in Aiken, S.C, who last year began conducting studies which involved shooting huge amounts of particulate matter, in this case “porous-walled glass microspheres,” into the stratosphere.

The project is closely tied to an idea by Nobel Prize winner Paul Crutzen, who “proposed sending aircraft 747s to dump huge quantities of sulfur particles into the far-reaches of the stratosphere to cool down the atmosphere.”

Such programs merely scratch the surface of what is likely to be a gargantuan and overarching black-budget funded project to geo-engineer the planet, with little or no care for the unknown environmental consequences this could engender.

What is known about what happens when the environment is loaded with sulphur dioxide is bad enough, since the compound is the main component of acid rain, which according to the EPA “Causes acidification of lakes and streams and contributes to the damage of trees at high elevations (for example, red spruce trees above 2,000 feet) and many sensitive forest soils. In addition, acid rain accelerates the decay of building materials and paints, including irreplaceable buildings, statues, and sculptures that are part of our nation’s cultural heritage.”

The health effects of bombarding the skies with sulphur dioxide alone are enough to raise serious questions about whether such programs should even be allowed to proceed.

The following health effects are linked with exposure to sulphur.

- Neurological effects and behavioral changes
- Disturbance of blood circulation
- Heart damage
- Effects on eyes and eyesight
- Reproductive failure
- Damage to immune systems
- Stomach and gastrointestinal disorder
- Damage to liver and kidney functions
- Hearing defects
- Disturbance of the hormonal metabolism
- Dermatological effects
- Suffocation and lung embolism

According to the LennTech website, “Laboratory tests with test animals have indicated that sulfur can cause serious vascular damage in veins of the brains, the heart and the kidneys. These tests have also indicated that certain forms of sulfur can cause foetal damage and congenital effects. Mothers can even carry sulfur poisoning over to their children through mother milk. Finally, sulfur can damage the internal enzyme systems of animals.”

Fred Singer, president of the Science Environmental Policy Project and a skeptic of man-made global warming theories, warns that the consequences of tinkering with the planet’s delicate eco-system could have far-reaching dangers.

“If you do this on a continuous basis, you would depress the ozone layer and cause all kinds of other problems that people would rather avoid,” said Singer.

Even Greenpeace’s chief UK scientist – a staunch advocate of the man-made global warming explanation – Doug Parr has slammed attempts to geo-engineer the planet as “outlandish” and “dangerous”.

Stephen Schneider of Stanford University, who recently proposed a bizarre plan to send spaceships into the upper atmosphere that would be used to block out the Sun, admits that geo-engineering could cause “conflicts between nations if geoengineering projects go wrong.”

Given all the immediate dangers associated with bombarding the atmosphere with sulphur dioxide, along with the unknown dangers of other geo-engineering projects, many people are concerned that “chemtrails” are a secret component of the same agenda to alter the Earth’s eco-system.

The fact that chemtrails are blocking out the sun, which is precisely what the geoengineering advocates call for, strongly indicates that they are an integral part of this dangerous and wide-reaching program.

The Government Is Already Geo Engineering The Environment 050908geo2
This graphic proposes, “Spraying aluminum powder and barium oxide into high levels of the atmosphere, again delivered by aircraft, to increase planetary reflectance (albedo) and cloud cover.” High levels of barium have been found in substances associated with chemtrails.

Reports of chemtrails, jet plumes emitted from planes that hang in the air for hours and do not dissipate, often blanketing the sky in criss-cross patterns, have increased dramatically over the last 10 years. Many have speculated that they are part of a government program to alter climate, inoculate humans against certain pathogens, or even to toxify humans as part of a population reduction agenda.

In conducting Google searches, one finds discussion, such as this example, of using sulphur dioxide as a jet fuel additive to be dispersed over the world during routine commercial flights.

“I suggest that both the sulphur dioxide and the silica particles could be delivered into the stratosphere by dissolving an additive in jet aviation fuel,” writes engineer John Gorman, who has conducted experiments to test the feasibility of such a scenario.

“We would want to burn fuel containing the additive specifically when the aircraft was cruising in the lower stratosphere,” he adds.

In 2008, a KSLA news investigation found that a substance that fell to earth from a high altitude chemtrail contained high levels of Barium (6.8 ppm) and Lead (8.2 ppm) as well as trace amounts of other chemicals including arsenic, chromium, cadmium, selenium and silver. Of these, all but one are metals, some are toxic while several are rarely or never found in nature.

The newscast focuses on Barium, which its research shows is a “hallmark of chemtrails.” KSLA found Barium levels in its samples at 6.8 ppm or “more than six times the toxic level set by the EPA.” The Louisiana Department of Environmental Quality confirmed that the high levels of Barium were “very unusual,” but commented that “proving the source was a whole other matter” in its discussion with KSLA.

KSLA also asked Mark Ryan, Director of the Poison Control Center, about the effects of Barium on the human body. Ryan commented that “short term exposure can lead to anything from stomach to chest pains and that long term exposure causes blood pressure problems.” The Poison Control Center further reported that long-term exposure, as with any harmful substance, would contribute to weakening the immune system, which many speculate is the purpose of such man-made chemical trails.

Indeed, barium oxide has cropped up repeatedly as a contaminant from suspected geoengineering experimentation.

KSLA also put aerosolized-chemical testing in its historical context, citing a voluminous number of unclassified tests exposed in 1977 Senate hearings. The tests included experimenting with biochemical compounds on the public. KSLA reports that “239 populated areas were contaminated with biological agents between 1949 and 1969.”

One of the accepted truisms of scientific study is the fact that if scientists are proposing an idea, then those scientists with access to the bottomless pit of black-budget secret government funding are already doing it.

It is highly likely that chemtrails are merely one manifestation of “geo-engineering” that is taking place without proper debate, notification or any form of legality, and with a callous disregard for the potential dangers to both our health and our environment.

The Chemistry Of The Modern Sky

Earth Day 2002

Earth Day approaches. A time for appreciation, reflection and action. Activists mobilize to defend the responsible stewardship of this precious blue sphere. Global warming remains the big issue on the podium and in Big Media. But the focus on chimney stacks and car exhaust rising from the ground is distracting world attention from a far more apocalyptic operation underway in the sky: global warming mitigation. While environmentalists have long argued that a warm, fuzzy blanket of greenhouse gas threatens to melt polar ice caps, one of the most ambitious global engineering initiatives in earth’s history may have already started above and over our heads.

Evidence is now literally floating in the air for various projects underway, documented by patents and confirmed by whistleblowers, in militaryspeak: aerial spraying, scattering and chaff operations. We, mere mortals on the ground, may use the term “chemtrails”, and without Our consent, it appears that heavy metals are being released into the upper atmosphere at an alarming rate – to save us from ourselves – as proposed in a paper delivered before the 22nd International Seminar on Planetary Emergencies, in 1997, by E. Teller et al.

The author, to be more precise, is ‘E’ for Edward, preceded by ‘Dr.’, the co-father of the H-Bomb and darling savant of the US Department of Defense and the military-industrial-academic establishment, the same Dr. T who in the 50′s invented a perky little radiation mascot, Readi Killowat, while proposing to create artificial harbours by nuking the coastline. Although we got the bomb, thankfully, the glowing harbours never got the green light. But on April 24, 2001, the New York Times confirmed that he had indeed “promoted the idea of manipulating the earth’s atmosphere to counteract global warming.” The Spin: a lining of aluminum chaff scattered into the upper atmosphere to create a sun screen – like a giant emergency blanket wrapping the earth – to reflect UV radiation back into space and save the world!

Brilliant! A chrome-plated planet. But here’s the catch: What goes up, must come down. Over three months, three separate rainwater and snow samples from Chapel Hill, North Carolina were collected and submitted for ‘double-blind’ laboratory analysis in March, 2002. Tests were ordered for several elements which should not be present in normal rain or snow. The result was devastating news about the health of our ecosystem: all samples consistently revealed enough of the following materials to indicate that they were present in the atmosphere “in large amounts…and concentrated form” through a “very controlled delivery (dispersion),” primarily: aluminum and barium.

Follow the chemical trail, from A-Z. Aluminum, inhaled or ingested, as we have all been warned, makes us forget the warnings that aluminum makes us forget….in other words: Aluminum – bad. Barium compounds that dissolve well in water (like rain) will cause a whole host of symptoms, from breathing difficulties to brain swelling. Barium is hygroscopic, a dessicant or drying agent: itchy eyes, burning throat, asthma, allergies, nose and lung bleeds. Barium – really bad. Just ask Readi Kilowatt’s chemical counterpart, Mr. Yuk! Most of us will remember the mean, green man who stopped us from downing a bottle of Bleach when we were six. The Mr. Yuk for our corner of earth is technically the EPA (Environmental Protection Agency) in the south, and Environment Canada, where it snows. However, barium hasn’t even been classified by the EPA with respect to human carcinogenity because no studies have even been done on people. Surprisingly, aluminum is also a no show on the list of hazardous air pollutants.

But check any Material Safety Data Sheet and you’ll find barium clearly marked: “DANGER! MAY BE FATAL IF SWALLOWED” with the “Health Rating: 3 – Severe (Life)”. Hey kids, bring out your “GOGGLES and GLOVES” Mr. Yuk’s taking you on a picnic! But, here’s the scary part, on the same Data Sheet, under Environmental Toxicity: “No information found”. Barium has twenty times more chronic lethality than the worse organic-chlorinated pesticide (private interview with R. Mike Castle, Nationally Accredited Environmental Risk Auditor). Confusing? Not really – nobody with enough acuity to read has been reckless enough to intentionally release barium into the ecosystem. Until now.

When anhydrous barium (mon)oxide reacts with water, forming barium hydroxide (commonly known as soluble barium salts), the chemical reaction liberates a lot of heat. And where there’s heat, there’s fire. Let’s connect the dots. Follow closely: February 17, 2002 UP Science News headlines, “Pollution drying up rainfall” – when particles are too small to seed nice fat raindrops, “the clouds that do form…have a hard time to rain.” These tiny particles are called “aerosols” by scientists, and long term exposure is now “an important environmental risk factor for cardiopulmonary and lung cancer mortality” (Journal of the American Medical Association). Bad news for the humans.

It gets worse for the earth, and here’s where the heat turns up: a third of the United States and even vast tracts of Canadian Prairie are suffering from acute drought conditions, some of the worst shortages in years. Rivers are literally drying up. Reservoirs are at record low levels. New York has declared a drought emergency. Montana is officially a drought disaster area. Even the UN warns of severe water shortages by 2025 – globally. Back to the lab: barium has a much lower “specific heat” value of 0.19 as compared to air (1.003) and water (4.184). When introduced at higher altitudes, barium will have a net effect of increasing the temperature of the atmosphere. Ergo: it gets hot and dry.

Why would anyone want to do that to the earth? Ask the military: In 2025 (a familiar date), US aerospace forces plan to “own the weather” by “capitalizing on emerging technologies and focusing development of those technologies to war-fighting applications.”(The Weather as a Force Multiplier, August 1996). In a summary table, under the column “DEGRADE ENEMY FORCES”, among all the nasty options we find: “Precipitation Denial – Induce Drought”. The smoking gun, not surprisingly always sits on the rack in a Department of Defense pick up truck. Technicians working at the Tesla Center, Wright Patterson Air Force Base, in Dayton, Ohio, have positively identified aluminum, barium, polymer webs with melanin, ethylene glycol-based monoacrylates and other heavy metals used extensively for weather modification projects for years (R. Mike Castle).

What a wicked, tangled web it is – literally. And here’s where we find the other half of our sandwich: DYN-O-Gel. Sounds like a product Ronco might distribute, but it is actually the trade name for cross-linked aqueous polymer, US Patent 6,315,213 awarded two years ago to one Peter Cordani – when dispersed into a storm it forms a gelatinous substance which falls to the ground, “thus diminishing the clouds ability to rain.” Dial-O-Matic in the weather!

And if you took your Pocket Fisherman to Florida Bay last month, you would have probably caught some of those “gelatinous blobs floating in it and spider-weblike filaments.” In January, fishermen in the Bay of Mexico began to report on a zone of lifeless water, about the size of Lake Athabasca, they dubbed “black water”. By early April, divers off Key West found dead and dying sponges, a trail of devastation and no answers. Clearly, none of the baffled marine biologists read Woman’s World magazine: an article in the March 19 edition proudly announced that a Florida research firm had discovered “a powder that will give you perfect weather every day,” and that in a top-secret test, this weather wonder drug was scattered over a storm by military planes. The company spokesman: Peter Cordani. The product: DYN-O-Gel. The Spin: it will “protect the lives of millions, but it’ll protect your leisure time, too.”

The most plausible explanation for “black water”: a recent real world test on a hurricane released enough Gel into the atmosphere to kill everything in the sea below. What goes up, must come down. So what about humans breathing in this miracle product? Mike Castle explains how these fine acrylic acrylate powders will suck all the moisture from your lungs, sticking the insides together – in two words: “extremely toxic”. Not advised.

Mr. Yuk take cover! The scientists are playing God but there are no environmental impact assessments for these compounds or any other kinds of weather manipulation chemistry. So why are they being sprayed into our skies?

Look Up! Connect the Dots. Follow the Patents. Smell the Air. Taste the Water. Control the Spin. Tell Everyone. The Truth is Copyright Free.

Discovery Channel performs pointless, invalid experiment.

by on Nov.21, 2009, under In the News

No mention of the patent for chemtrailing thru the jet fuel?

These lab tests are so rigged I don’t even know where to begin. First of all it’s not double-blind. This completely invalidates the results of this corporate media “study.”

Who’s to say where this sample of jet fuel they “purchased at random” from a local airport really came from?

The proper method to test for barium and aluminum in air would be to take particulate samples by filtration at varying proximity to airports, and chart the composition of the captured particulates by mass spectrometer analysis. Some control samples would be purified air. Other control samples would be purposefully contaminated with barium and aluminum. Experimental samples would be actual atmospheric air. All samples would be numerically coded and scientists would not know which samples they were testing. Testing would be conducted by multiple independent labs who would not be told the nature of the test they are conducting.

What is the purpose of all the strobing (white flashes) while they are explaining how aluminum should not be present in jet fuel?

And why are we not looking for barium? Why are they making it about aluminum?

“The US Air force did not release a sample of their high performance jet fuel”

“We need to take advantage of everybody on this planet to help solve the problem of global warming. If we can do it with some form of climate engineering, all the better.”

Caution urged over cloud seeding

by on Sep.23, 2009, under In the News, What are they?

Justine Davies

6 August 2009 | EN

Scientists who have produced the first robust proof that cloud seeding can increase long-term rainfall are urging developing countries considering the technology to be cautious.

Cloud seeding involves injecting clouds with chemicals that encourage water vapour to form ice crystals heavy enough to fall, melting on their way to produce rain. Chemicals can be injected into clouds using aircraft or by launching rockets.

The researchers — led by Steven Siems, an associate professor from Monash University, Australia — examined more than four decades of cloud seeding experiments in Tasmania and found rainfall was at least five per cent higher over seeded areas.

But co-author Anthony Morrison points out that clouds in Tasmania contain vast amounts of supercooled liquid water and are unusually clean — making them particularly suitable for cloud seeding.

And Siems wants more research, saying, ”There could be other explanations for the increased rainfall — although we suspect that cloud seeding is a significant contributor.”

He told SciDev.Net that promoting cloud seeding to developing countries is “probably not a good thing to do”.

“There are many, many unscrupulous people in the field of weather modification who up until now have promoted some methods without any proper scientific evidence. Developing countries are particularly at risk here,” says Siems.

The technique ”remains controversial, especially because in the early days unrealistic claims were made about its success”, says Johannes Verlinde, associate professor of meteorology at US-based Pennsylvania State University.

Another reason for the controversy, he says, is that no two clouds are alike, making it difficult to compare clouds to prove it really works.

Siems cautions that developing countries should carefully consider whether cloud seeding is right for them and avoid other unproven techniques.

Roelof Bruintjes, of the National Centre for Atmospheric Research in Colorado, United States, agrees, and says that there are many companies promoting techniques such as ‘ionisation’ — where charged particles in the air are claimed to act as nuclei for rain drops to form — that have not been scientifically proven.

The problem, he says, ”is that people are desperate and in some cases are willing to try anything”.

However, he also says cloud seeding may be an economical way to enhance water resources in some developing countries. Bruintjes’ own organisation is helping Mali monitor cloud seeding experiments.

But he “would advise all governments considering cloud seeding to conduct tests first to see if it is going to work for their country”.

The research was published in the June issue of the Journal of Applied Meteorology and Climatology.

Arrogant scientists and Obama administration should recall the story of the old lady who swallowed a fly.

by on Apr.08, 2009, under In the News

Pea-brained, arrogant Obama administration scientists recommend spewing more pollution into the atmosphere to “solve global warming.”

Wouldn’t it make more sense to invest the money in alternative energy production and/or install better scrubbers on all coal/gas smokestacks?  It would be orders of magnitude more efficient to catch the pollution at the source rather than to try to sequester it from the atmosphere once its already been released and dispersed.

Please keep in mind, co2 makes up a fraciton of 1% of our atmosphere

By the way there’s snow on the ground right now outside my office, and its April.

Regardless this new proposed aerosol dispersal is a terrible idea just as the secret aerosol chemtrail program is.

. . .

WASHINGTON (AP) — Obama looks at “climate engineering”

The president’s new science adviser said Wednesday that global warming is so dire, the Obama administration is discussing radical technologies to cool Earth’s air.

John Holdren told The Associated Press in his first interview since being confirmed last month that the idea of geoengineering the climate is being discussed. One such extreme option includes shooting pollution particles into the upper atmosphere to reflect the sun’s rays. Holdren said such an experimental measure would only be used as a last resort.

“It’s got to be looked at,” he said. “We don’t have the luxury of taking any approach off the table.”

Holdren outlined several “tipping points” involving global warming that could be fast approaching. Once such milestones are reached, such as complete loss of summer sea ice in the Arctic, it increases chances of “really intolerable consequences,” he said.

Twice in a half-hour interview, Holdren compared global warming to being “in a car with bad brakes driving toward a cliff in the fog.”

At first, Holdren characterized the potential need to technologically tinker with the climate as just his personal view. However, he went on to say he has raised it in administration discussions.

Holdren, a 65-year-old physicist, is far from alone in taking geoengineering more seriously. The National Academy of Science is making climate tinkering the subject of its first workshop in its new multidiscipline climate challenges program. The British parliament has also discussed the idea.

The American Meteorological Society is crafting a policy statement on geoengineering that says “it is prudent to consider geoengineering’s potential, to understand its limits and to avoid rash deployment.”

Last week, Princeton scientist Robert Socolow told the National Academy that geoengineering should be an available option in case climate worsens dramatically.

But Holdren noted that shooting particles into the air — making an artificial volcano as one Nobel laureate has suggested — could have grave side effects and would not completely solve all the problems from soaring greenhouse gas emissions. So such actions could not be taken lightly, he said.

Still, “we might get desperate enough to want to use it,” he added.

Another geoengineering option he mentioned was the use of so-called artificial trees to suck carbon dioxide — the chief human-caused greenhouse gas — out of the air and store it. At first that seemed prohibitively expensive, but a re-examination of the approach shows it might be less costly, he said.

Another theory about hole-punched clouds

by on Feb.14, 2009, under Satellite Imagery, What are they?

This NASA satellite photo lends itself to the idea that jet exhaust causes vapor to condense into larger ice crystals which then fall out of the sky, making the downward cirrus wisps we see in these photos. Also note that barium is hygroscopic (absorbs water).

NASA: hole-punched clouds “very unusual,” could be “facilitated by a passing airplane exhaust”

by on Feb.09, 2009, under What are they?

From NASA Astronomy Pic of the Day site. Also see my other post “Anomalous holes burned in clouds

NASA can be a valuable source of information, but I never take anything it says at face value. They do a lot of amazing research, but ultimately they work for the military industrial complex.

NASA’s Explanation: What could create a huge hole in the clouds? Such a hole, likely hundreds of meters across, was photographed last month from a driveway near Mobile, Alabama, USA. Very unusual to see, hole-punch clouds like this are still the topic of meteorological speculation. A leading hypothesis holds that the hole-punch cloud is caused by falling ice-crystals. The ice-crystals could originate in a higher cloud or be facilitated by a passing airplane exhaust. If the air has just the right temperature and moisture content, the falling crystals will absorb water from the air and grow. For this to happen, the water must be so cold that all it needs is a surface to freeze on. The moisture lost from the air increases the evaporation rate from the cloud water droplets so they dissipate to form the hole. The now heavier ice crystals continue to fall and form the more tenuous wispy cloud-like virga seen inside and just below the hole. Water and ice from the virga evaporates before they reach the ground.
