There are numerous threads about chemtrails on ATS - and none of them ever seem to go anywhere - just the same out arguments repeated ad nauseum.

Perhaps it's time we tried a different approach?

There is a well known and well documented explanation for the phenomena which some people claim to be chemtrails: they are persistent contrails formed by well understood atmospheric processes by perfectly normal aircraft.

So, perhaps, in order to prove chemtrails exist, we can debunk this theory? That would then finally pave the way for us to debate what else they might be. Let's see if we can prove that the 'chemtrail/persistent contrail' phenomena is new and cannot be explained by normal atmospheric processes etc

So come on you you chemtrailers - here's your chance to prove us meteorologists and aviation experts wrong.

Lets' start by looking at a few well known papers and reports. Let's see if we can debunk any or all of them


One aspect of weather pollution in the atmosphere is the generation of contrails. The spreading out of jet contrails into extensive cirrus sheets is a familiar sight. Often, when persistent conditions exist from 25,000 to 40,000ft, several long contrails increase in number and gradually merge into an almost solid interlaced sheet


Kuhn, 1970

Surface observations from 1971 to 1995 show that cirrus increased significantly over the northern oceans and the United States

~ ~ ~

It is concluded that the U.S. cirrus trends are most likely due to air traffic

~ ~ ~

... the cirrus trends over the United States are estimated to cause a tropospheric warming of 0.28–0.38C decade21, a range that includes the observed tropospheric temperature trend of 0.278C decade21 between 1975 and 1994.


Minnis etal 2003

Researchers are investigating how air travel can be adapted to ease its impact on the environment.

The investigation focuses on how aircraft can avoid creating vapour trails, also known as contrails. These spindly threads of condensation may not seem important but some persist for hours and behave in the same way as high altitude cirrus clouds, trapping warmth in the atmosphere and exacerbating global warming.


Press release from Imperial College, London, 2005

Also have a read of:

Contrail Uncertainties

Aviation and Global Climate

Can we prove that these studies are wrong?

If so we can say that the normal explanation for 'chemtrails' is flawed and that the various conspiracy theories might be worth reassessing



Over to you!

Outstanding thread and OP. I don't have much to add other than an interesting bit I read in the October edition of Aerospace America, the periodical for the AIAA (American Institute of Aeronautics and Astronautics) of which my wife is a member.

The article was about "Engineering a Fix for Global Climate Change" (read Global Warming).

One of the ideas being researched is to shade the Earth by using specific materials that would hang in the atmosphere and either reflect the UV rays or absorb CO2. The suggested (and only practicle) method of distributing these materials is by discharging them out of the aft end of aircraft.

While the article goes on to say that this concept is not in use and is only in the early research stages the researchers are very conscious of the fact there could be side effects of this activity that could be worse than the problem they are trying to correct.

I mention this here because I can see the "Contrail" folks getting VERY excited if one day they really do see a jet crossing the sky spraying something into the atmosphere.

Weather manipulation is nothing new.

It has been going on for decades.

It has been used since
1976.

There are reports, that U.S.Air Force used certain chemtrails to extend the monsoon seasons in Vietnam, so that the supply roads, which were basicly dirt-trails, after the extended monsoon season turned to mud.

Russians are also doing it - and have been doing it for a long time.

And let us not forget the Chinese - who say, there shall be NO RAIN for Olympics.

Everybody else, who claims that there are no chemtrails is in my humble opinion part of this weather modification programs. Or just does not want to wake up...

Bravo, I applaud you.

I know I have tried to also awaken people to the fact that Chemtrails are the real deal and people from all over this planet are reporting in with specimens and finding many interesting things.

Rat poison (Barium Salts) for one. When you look up in the evening and see those all so pretty pink/purple clouds. They also have found things like Red Blood Cells, so many things you just can't believe they would do this.

People when taking photo's of these trails have also captured ufo's in and around these trails. The question is are the ships monitoring these trails and collecting specimens and testing them themselves or are they involved.

I have asked people (a few times in different thread) to look up and just observe there skies everyday it only takes a minute here and there throughout your day.

After this became known the peoples studing this found that peoples doing this spraying must have been observing there sites because they started to change there routine in there spraying but this just became a joke in a way.

The junk being sprayed is coming down and it is harming you, your family, your pets. It is harming the air, soil, water.

When Springer mentioned CO2 for example he hit on something major.

I could sit here until I am blue in the face (AGAIN) and tell you this and know you don't believe me when I write that but I am trying my best to warn you of what is happening.

I am a human with an Alien Soul. I have been told over fifty years ago by them that for every TREE that is destroyed it must be replanted ten fold, we had not done this. We as a people are finally waking up but the time is critical and Trees and plants need to be planted xxxxxx's ten.

Have you ever heard which I am sure you have of the TREE OF LIFE.

Trees and plants will clean the CO2 and replenish our OXYGEN SUPPLY. (cough, cough/ hint, hint)

If you want to live I suggest you start planting.

One of many sites on chemtrails to get you started:

groups.yahoo.com...

I really don't mean to sound harsh I am trying to help people even if it makes me sound...........................

Essan:

Does one obviate the other? I agree with you that the contrail spreading effect is well known and has a mundane explanation.

But.

Living in Huntsville for a while, you see a lot of atypical contrails, and I don't mean the sort that spread as you described.

We were out around the pool one day and watched a couple of non-commercial jets leaving contrails that were hard to believe. I say non-commercial because they were not on the "normal" flight path into the airport and they were looping around the Huntsville/Madison area making figures - triangles, circles, crosses etc. And what was most striking, was that toward the end they were making figures with dashed lines. I'm not sure how you get a dotted line formation with a normal contrail. Now, I'm not saying that the crazy flying over the Huntsville metro area was all that unusual - there are "hotshots" that do that from time to time, we always assumed it was astronauts flying in.

But the dotted line thing was just jaw-dropping. Maybe there's an explanation for it.

Another time we saw (it was about 3 AM) what we counted as four airplanes laying down a very nice crosshatch over the area for hours. I guess that could be explained but it was not only creepy it was sort of attractive in an odd way with the full moon overhead lighting it up.

And last but not least was the jet that laid a trail over downtown - at a low enough altitude that you could read the markings on the plane. No joke, he couldn't have been 1000 feet up. I guess he could have had an oil leak in a turbine, but it was nice and thick with the occasional lumps falling out of the trail leaving a spiral smoke trail.

Anyways, I don't believe the contrail thing by half (I sure don't believe anything on the "carnicom" site as some of the posters do) but those things stuck in my head as being really unusual. Any of them could have mundane explanations but just looked really odd.

What's to be offended about? There are well-known reasons (at least to meteorologists and atmospheric physicists) for "spreading to cover the entire sky" in some circumstances, which may not be all that rare.

It's not so much lying as not understanding what they're seeing. Quite a few people aren't very good observers and have only the most tenuous of grasps on science-based subjects.

Jim Phelps is a fantasist. But how does he debunk the existence of supposed chemtrails in 1970?


I'm offended by your assumption that millions of people are lying about what they are seeing, feeling, and reading.


I'm not accusing anyone of lying

But why can no-one dispute the meteorological explanation for 'chemtrails'??????

i just watched a ufo film on google this afternoon part of which at the end showed on a weather satellite the contrail of a vehicle that left usa airspace starting from nevada making its way across to the east coast overflying europe ,russiah and then china-------all on the edge of space but not in orbit------the speed of this ufo? calculated at 8000 miles per hour--------the guess given was that it was an aurora mission----- the replacement ship for the sr-71 blackbird.
