My name’s Patrick Roddie, I’m a San Francisco-based  anti-geoengineering activist and researcher who runs

Today’s hearing is supposed to address whether greenhouse gas emissions from aircraft endanger public health. When you mention greenhouse gas, most people think of carbon dioxide – a trace gas essential to all life on earth.

But CO2 represents just 3% of the planet’s greenhouse gas – 95% of it is water. Even preschoolers know overcast skies make the nights warmer and days cooler. Clouds insulate, trapping heat and reducing the temperature range from the night’s lows to the day’s highs.

Which brings me to persistent contrails. All but the willfully ignorant know our skies have changed dramatically over the past few decades. The dark blue skies of our childhood have been replaced with a milky white haze, criss-crossed with fast expanding persistent contrails, stretching from horizon to horizon and spreading out to cover the sky. These trails can stretch for thousands of miles and can be seen by anyone visiting  These trails persist regardless of altitude, temperature, humidity or other atmospheric conditions. Persistent contrails used to be rare, but have now become an everyday phenomenon all over the world. If physics hasn’t changed, what has?

So what makes these trails form, persist for hours and stretch thousands of miles? Which condensation nuclei are they forming on and are these harmful to human health?

Geoengineers propose spraying tens of millions of tons of reflective particles into the atmosphere in an attempt to reflect sunlight back into space and reduce global warming. This is known as Solar Radiation Management, Stratospheric Aerosol Injection or Albedo Modification. This process, patented by defense contractor Raytheon, is quite simple. Tiny particles sprayed from jets would act as condensation nuclei, attracting atmospheric water vapor to form persistent artificially nucleated contrails which would then spread out to form artificial cirrus cloud cover.

When geoengineers discuss Solar Radiation Management in public, the only substances they say they’d consider spraying are sulfates or sulfuric acid. However, their own literature concludes that sulfates have limited effectiveness and that highly toxic nano particles of aluminum and barium should be used instead. And when confronted, they doggedly refuse to address the human health impacts of their proposals. Other geoengineers are more candid about their plans to poison the sky. Stanford’s  Ken Caldeira admitted in 2006 that he discussed putting pathogens in clouds to wage chemical and germ warfare on civilian populations when he worked at a government weapons lab. It’s no surprise the public doubts these scientists have their best interests at heart.

Last month I brought this paper to the Paris Climate Conference addressing the adverse human health effects of proposed geoengineering solutions. I formally request it be entered into the record. It documents the dramatic increase of Alzheimer’s and respiratory failure since the 1990s when persistent contrails became commonplace around the world. I conclude that these persistent contrails are in fact artificially nucleated with the toxic particulate metals outlined in Raytheon’s patent and that a Solar Radiation Management program has been deployed since at least the 1990s.

Weather modification research is nothing new; the earliest patent dates back to 1920. Raytheon’s patent proposes reducing global warming by injecting aluminum, thorium and other metallic oxides in the 10-100 micron range into the stratosphere using jet exhaust.

The US Navy patented another delivery method which forms artificially nucleated contrails from metal oxides with a 0.3 micron particle size. Other methods include airships, rockets, chimneys and slurry pipes.

The best known proponent of Solar Radiation Management is Dr David Keith. He told the 2010 annual meeting of the American Association for the Advancement of Science that aluminum oxide has four times the volumetric radiative forcing for small particles as does sulfur and 16 times less the coagulation rate. Sulfur particles stick together and quickly fall out of the stratosphere and are much less effective per unit mass. He also said a nano fabrication study proved it was very simple to spray high quality alumina particles from a plane by injecting alumina vapor into the exhaust.

His 2010 paper, “Photophoretic levitation of engineered aerosols for geoengineering,” proposes spraying 50nm thick discs of aluminum, barium, titanium and ferrite instead of sulfates.

Pope et al also concluded aluminum nano particles were much more effective than sulfates in a 2010 perspective in Nature Climate Change.

The Material Safety Data Sheet for nano particulate aluminum oxide states it’s an irritant to the respiratory system, is implicated in Alzheimer’s disease, can cause pulmonary disease, tumors and neoplasms and should also not be released into the environment without proper governmental permits.

Alzheimer’s disease rose to the 6th leading cause of death in the US from the 8th between 1999 and 2013. In 1994, it didn’t even make the top ten. Now people in their 20s are showing signs of Alzheimer’s.

Research shows that aluminum accumulates in the brain, bones and kidneys, is a neurotoxin, accelerates brain aging, increases oxidative stress and inflammation of the brain and is seven times more bioavailable when inhaled than when ingested orally

Barium is much deadlier. According to its Material Safety Data Sheet, exposure to barium salts can cause pulmonary arrest, vomiting, diarrhea, convulsive tremors, muscular paralysis, shock, convulsions and sudden cardiac failure. Barium targets the cardiovascular, nervous, gastrointestinal, hematology, respiratory, reproductive and renal systems as well as the adrenal glands and liver. It is also an irritant to the skin and eyes and should not be released into the environment.

In 2011, respiratory failure overtook stroke to become the third leading cause of death in the United States, at a time when smoking was at an all-time low, emissions standards on vehicles and power plants were at their strictest and heavy industry had relocated to China.

Hundreds of scientific papers thoroughly prove the toxicity of both aluminum and barium – ­ it would take days to cover a fraction of the proof.

According to EPA, particulate pollution can cause early death from heart attack, stroke, congestive heart failure and chronic obstructive pulmonary disease. It also causes asthma and inflammation of lung tissue and may cause cancer, reproductive and developmental harm. Particulate pollution can lower life expectancy by one to three years.

Water and ice have refractive indices of 1.333 and 1.309 respectively and produce rainbows with an angular radius of 42 degrees, centered on the antisolar point.

But in recent years a formerly rare phenomenon has become commonplace, a 21 degree halo completely encircling the sun. Some argue that these halos or “incredibly rare sun dogs” are formed by ice crystals, but nothing can change the refractive index of water or ice ­- which form 42 degree halos. Metal salts have a higher refractive index and therefore form much tighter halos. Crystalline aluminum oxide, for example, has a refractive index of 1.762-1.778 while barium sulfate has a refractive index of 1.636.

My contention that these “incredibly rare sun dogs” are formed by metal salts with a higher refractive index than water is reinforced by rainwater analysis taken during a 30 day period when I recorded 21 of these halos in March/April 2015. I collected rainwater in clean glass bowls on the roof of my San Francisco apartment building on April 5th, 2015, six thousand miles downwind from the nearest factory, power plant, refinery, freeway, quarry or mine. I sent it to a NELAP certified lab and they recorded barium at a staggering 160 micrograms per liter. Less than a gram will kill an adult human.

An earlier test of rainwater collected in January 2014 recorded aluminum at 190 micrograms per liter. I submit both these rainwater tests into the record.

San Francisco’s air should be pristine: we get prevailing winds from the Pacific Ocean. Why is it left to concerned citizens to pay for our own rainwater analysis – and why did EPA stop publishing data on airborne aluminum in 2002? Let me take this opportunity to formally submit a freedom of information request for EPA to release the historical results of metal levels in our air and rainwater from the 1980s to the present.

I have recorded hundreds of time-lapse videos showing the progression of these persistent contrails since 2011. Thousands of others worldwide have also documented the alarming increase of these persistent contrails and been met with deafening silence from supposedly green organizations like Greenpeace – ­ a proud partner in the Solar Radiation Management Governance Initiative ­ – and all governmental agencies, including the EPA.

Your mandate is to protect the environment, especially the air we breathe. I wouldn’t expect you to admit the existence of a program as covert as the Manhattan Project – even one blatantly obvious to an increasingly aware and outraged populace –  but when a geoengineering program is causing millions of premature deaths a year you must do more than pass the buck back and forth between other three letter agencies.

Do your job. History will judge you on your actions – and inaction.



  • Thank you for bravely going on record and exposing this hideous crime against humanity! I live in Florida and have watched the Sunshine State turn into the chemtrail state. Over the last 5 years, we have been inundated almost every day with these trails that span out and cover our skies. They even spray us throughout the night. Very recently, we have experienced heavy rains (not normal) which have lasted hours and hours. I can only imagine what is in that rain water. When the real clouds dissipate, the evidence of the crime sits above us. What is worse is that I have contacted both the local EPA (at the county level) and even the state level. Both state they can’t do anything because “we only address the issue if it falls on the ground.” I do everything that I can to expose this issue, particularly on Twitter. I post pictures of the crime all the time. And that halo around the sun, yes we have had it here also. Those little rainbows that appear from cloud to cloud but never touch the ground, we get those also. I see so many pictures posted where the sky is filled with chemtrails at sunset and people think it is so beautiful. Such a shame that this crime has not been truly exposed. Thank you again for doing your part to raise this issue and question the very authority that is there to protect us and their profound failure to do so.

  • Thank you very much sir for your efforts and testimony. The video of the testimony makes an excellent pass-along to unaware friends and neighbors, and your link to the Nasa resources is a boon. I’m new to your specific work; your site is a tidy resource (more digestible, for instance, than Wigington’s site). I look forward to finding the rest of your work.

  • Thanks so much for this website and all your efforts to bring attention to the this massive world wide crime against humanity. I have been sickly aware of this (silent weapon) activity for many years and can’t believe everyone on the planet isnt screaming blue murder. My own intuition has been telling me lately (for what its worth) that the purpose of the chemtrails is much darker than any agency will ever admit to.
    It is either being done (imho) to prevent humanity’s natural progression to a higher level of conciousness, or prepare us for a massive psy-op or lastly to promote a massive reduction in the population.
    Please be safe Edmonton Alberta Canada

  • Thank you for your efforts, dedication, bravery and persistence. My entire family is well aware and concerned of the contrails and I speak for all of them as I again say thank you. As you said in your testimony, history will judge you for your actions and I dare say it will judge you well. I wish I could clone you and put a few million copies in D.C.!

    God bless you for all your days

  • I have watched your speech on the “Global Research” web site and I would like to thank you for your concise, factual points and requests made. It is at least a start.

    As pointed out in a couple of the other comments, I believe that the frequency of the “spraying” is dramatically increasing. For example I live in the eastern part of the Netherlands and whilst we have daytime flights which is not unusual, recently there have been many night flights that I have watched as best I can. At first I believed them to be military aircraft going Eastwards – maybe some were, but unbelievably some make a rather large circling route seemingly going back to where they came from.

    The reason, this is of further interest to me, away from the conspiracy theorists, is that 4 years ago, I was diagnosed with a cancer known as Nasopharyngeal carcinoma (NPC) it is a cancer is caused by a combination of factors: viral, environmental influences, and heredity and is most common in Asian people.

    The tests show it wasn’t viral (EB), nothing on the hereditary side and therefore by default and my view, it is down to the environmental influence. The environmental influence usually being down to particulate matter (they usually state wood)

    I was a strapping bloke before I moved here, then after a year or two, the problems started. I have researched contrails or chemtrails ever since.

    Keep up the good work ad good luck

    Best Regards


  • Thank you for all you do, because I already gave up trying to make people around me to see the obvious… or care!
    Perhaps the “side effects” of this spraying are showing desirable results: total ignorance and lack of awareness of one’s surroundings. The most frightening part of it is, that our children will not know clear deep blue skies, and there will be no one to tell them about it, if people in their 60’s can not tell the difference today, or are afraid to see…
    most sincere, Aleksandra

  • Patrick you were excellent along with Max Bliss at the EPA hearing.
    I’ve distributed flyers with you at the Ferry Bldg on Saturdays; any more Sats planned?
    Used to see dates on this site.
    thanks, kathy

  • Hi, Patrick!

    Will you let us or me know which lab you used or how to go about finding one AND requesting the proper tests for air and water and soil, in such a way that one is not mocked or dismissed? I have tried to get info from one recommended by Elana Freeland, about testing our air and water here in Sedona but perhaps they are not willing or perhaps I am asking for the wrong kind of tests. The city would like for me or the group I started to pay for it but we think they should. I just need to get a quote and break it down for them. Is it a bad idea to name the reliable labs publicly? If so, please just email me. I am to speak briefly at a city council work session on September 9th about of holding a public hearing here in Sedona on the subject of geoengineering (you are invited to speak, if we get one!) and I want to have some info about valid, reasonably-priced testing by then.

    Thank you, Patrick!

  • I live in the foothills east of Sacramento and I am appalled at the unmitigated audacity of these bastards! It’s 5 pm Sunday, August 23, 2015 and the sky is loaded with these suspicious looking long narrow “clouds” and the more I research the phenomenon, the madder it makes me! It is simply unthinkable that our government allows this to continue on a regular basis and that our current drought has its basis in this insane program. It has to stop! We as citizens of the state, country and the world simply have to find a way to reverse this situation.

  • Thanks for putting this well on the record. The deniability of this activity is pretty much impossible these days with the data we have. Since the evidence is there and the ‘officials’ do nothing, they should be served with a notice that they may be PERSONALLY responsible for their actions and inactions and may also lose their position or worse, be jailed. A strong message needs to be sent to our friends ‘in office’ who continue to bow to the pressures of organized crime. They need to have painful consequences for their cooperation or they will continue to cooperate.

  • MY COMMENT POSTED ON THE EPA SITE:!submitComment;D=EPA-HQ-OAR-2014-0828-0001

    My name is Albert Krauss, residing at xxxx Street, Ukiah, CA 95482. I have lived in Northern California for the past 45 years, and in Mendocino County for most of that time.

    My demographic is “senior citizen, age 83, white male”, with 5 children, 9 grandchildren, and 2 great grandchildren – all living within a 60 mile radius.

    In the past I tended to consider “chemtrails” a minor visual annoyance, and possibly an interesting experiment in “rain making”, contemporary experimental science style.

    Over recent months, possibly for the past year or so, I have had my attention drawn to the increasingly prevalent visual phenomena of the “vapor” trails (referenced also, above, as “chemtrails”). They criss cross the sky, with almost daily frequency, except when strong atmospheric weather patterns, prevailing Westerlies, etc., disperse them.

    However, in reading the “caveats” presented in a transcript of geo-engineering researcher Patrick Roddie’s comments before your agency (transcript posted on the website, I have become deeply concerned that the public is being/has been deceived regarding the safety and objectives of this apparently wildly uncontrolled quasi-private experiment in our very public, worldwide skies.

    There seems to have been no transparency concerning the objectives, technology, and possible consequences to human health.

    The proposed rule/rules may exert an element of control over what seems to be a wildly uncontrolled experiment.
    Thank you for your attention to my comment and my concern.

    Look around see what you do,
    Everybody smiles at you.

    Hey you with the pretty face,
    Welcome to the human race
    A celebration Mr. Blue Sky’s
    Up there waitin’ and today
    Is the day we’ve waited for


    Mr. Blue you did it right,
    But soon comes Mr. Night,
    Creepin’ over, now his
    Hand is on your shoulder,
    Never mind I’ll remember you this way.
