Contrails dissipate quickly whereas chemtrails linger?

Categories: [ Chemtrails ]

Contrails over London in 1944

Vapour trails left by British bombers on route to attack flying-bomb sites encircle the dome of St. Paul's Cathedral. London, 1944.

All those who passionately believe that "contrails dissipate quickly" whereas "chemtrails linger" and are deeply offended by the sceptical position that TNRA takes in regard to these claims, are free to "unlike" Truth News.

If, on the other hand, you would like to engage in rational debate, you're most welcome to do so.

However, please be advised that the information I have to impart may be shocking and difficult to grasp if you have been a "chemtrail alarmist" for a long time.

The often cited claim that "normal contrails dissipate quickly" is total bunkum.

There is not a shred of science to backup that claim. Nothing, nada, zippo!

Those who promote this idea are simply repeating something they read on a web page without checking sources.

CONTRAIL SCIENCE

For a contrail to form, suitable conditions must occur immediately behind a jet engine in the expanding engine exhaust plume. A contrail will form if, as the exhaust gases cool and mix with surrounding air, the humidity becomes high enough (or, equivalently, the air temperature becomes low enough) for liquid water to condense on particles and form liquid droplets. If the local air is cold enough, these newly formed droplets then freeze and form ice particles that make up a contrail.

Because the basic processes are very well understood, contrail formation for a given aircraft flight can be accurately predicted if atmospheric temperature and humidity conditions are known.

After the initial formation of ice, a contrail evolves in one of two ways. If the humidity is low, the contrail will be short-lived. Newly formed ice particles will quickly evaporate. The resulting contrail will extend only a short distance behind the aircraft. If the humidity is high, the contrail will be persistent. Newly formed ice particles will continue to grow in size by taking water from the surrounding atmosphere. The resulting line-shaped contrail extends for large distances behind an aircraft. Persistent contrails can last for hours while growing to several kilometers in width and 200 to 400 meters in height. Contrails spread because of air turbulence created by the passage of aircraft, differences in wind speed along the flight track, and possibly through effects of solar heating.

Thus, the surrounding atmosphere’s conditions determine to a large extent whether or not a contrail will form after an aircraft’s passage, and how it evolves. Other factors that influence contrail formation include engine fuel efficiency, which affects the amount of heat and water emitted in the exhaust plume.

TNRA is informed by science and is not interested in propping up anyone's belief systems, and we don't apologise for that.

But, please, don't take it from me, speak to any meteorologist or any pilot and they'll tell you straight, that there is HUGE variation in the length and persistence of contrails. Sometimes they don't form at all, other times they form, but disspate quickly, other times they persist and spread out.

That's the facts folks, and it's been that way since planes first went up in the sky.

If you believe otherwise, I'm afraid you've been conned.

Forgive me if I seem rude or impatient on this topic, but every few months I come across a new wave of people who have been subjected to the same false propaganda about chemtrails, and I have to run the same arguments and cite the same articles over and over again. It does wear one's patience down.

Before making some kind of angry reply, I urge you to read this article and associated links. It's fairly detailed, and deals with most of the usual claims made by chemtrail alarmists.

Finally, let me qualify all this by saying that I do not doubt that geo-engineering programs exist, and that, indeed, some of the patented techniques discussed at international forums include the creation of artificial cirrus cloud. Does this, however, entitle you to conclude that every spreading contrail you see is an example of such geo-engineering?

Think about it.

How’s this for a burst of bullshit from HEREWARD FENTON posted by himself?

But, please, don’t take it from me, speak to any meteorologist or any pilot (and I am an Airline Transport Pilot with 14,000 logged in a number of countries including, but not limited to Canada, but as my views conflict they don’t count, apparently. - LEONARD CLAMPETT) and they’ll tell you straight, that there is HUGE variation in the length and persistence of contrails.

So much for HEREWARD FENTON not propping up anybody’s belief system.

Josh Anonymous is a waste of time and energy because he believes he is an authority on meteorology apparently, but claims that there can be supersaturation in a clear blue sky where, because the atmosphere is not sufficiently saturated, no cloud has formed, then claims that an aircraft passing by can create cloud. Balderdash and poppycock is the appropriate phrase to suit this line of argument.

This is not my claim. It’s contrail science since 1953, as summarized here:

“Surprisingly, at cold temperatures ice clouds (including contrails) can form and persist at humidities lower than 100%. The red line (dash-double dot line) in the Appleman chart shows at what humidities contrails can persist (usually between 60% and 70% relative humidity). Thus, if the air is moist enough, and colder than (temperature profile is to the left of the red line), then the Appleman chart indicates that persistent contrails can form.” (Emphasis is mine)

For the graph mentioned in the quote you will also find plenty of examples on the net.

Do you think Mr. Appleman got it all wrong?

By Josh on 2014 12 04 - 19:37:35

Leonard Clampett,

of course I intended to adress you instead of Andrew Adams in the previous post.

Regarding your credentials as a pilot: you make it really hard for others to take you seriously.

1. You extensively promoted your misunderstandings about combustion of carbon-based fuels, even after Qantas pilot Michael Glynn confirmed that it always generates water.

2. You denied the existence of ice supersaturation in the atmosphere.

3. You claimed you could determine the distance / altitude of a contrail with your bare eyes.

4. You seem to have forgotten my full name that I gave you just recently.

All your flight hours are meaningless as long as you demonstrate such a profound lack of understanding, without even being willing or able to correct your position.

By Josh on 2014 12 04 - 20:06:37

dickhead josh quoting paid shill m glynn who goes around telling people that planes are going to be shot out of the sky by people who object to nefarious activities by people like him.

much easier to take out dickheads like glynn on the ground, as i dont think the average concerned citizen has access to ground to air missile launchers..

you ######### really are special.

By Andrew Adams on 2014 12 07 - 05:57:57

Andrew Adams,

Michael Glynn is primarily concerned about personal threats on the ground.
Are you aware that you just confirmed his concern?

And where is your evidence that he is involved with “nefarious activities” ? Or are we back at lynch law ?

So Andrew Adams… Are you making a public threat against me?

By Michael Glynn on 2014 12 07 - 09:01:47

@ dickheadf josh

“Michael Glynn is primarily concerned about personal threats on the ground.”

you just cant stop being a dickhead can you? - he said he was concerned about being shot out the sky idiot..

And where is your evidence that he is involved with “nefarious activities” ?

ha! as soon as his name is mentioned he is right back here at disinfo central…

@ ####### glynn

“So Andrew Adams… Are you making a public threat against me?”

lol - are you publicly declaring yourself to be a dickhead?

what i am saying you pathetic retard.. is if people really wanted to cause harm to others, it would be much easier for them to do it while they are on the ground, rathen than trying to source a ground to air missile launcher and then patiently wait for their target to fly over wherever it is they have the weapon located. it is pretty clear.. it would be much easier that way than to shoot you out the sky as you were ever so worried about.

how long ago did you make that wild accusation and how many have been shot out the sky since? and - as you were asked before but didnt answqer, where do you think people are going to get these weapons?

what a ########.

By Andrew Adams on 2014 12 08 - 11:25:20

Are you aware that you just confirmed his concern?

how did i confirm his concern? by pointing out the stupidity of his fear of being shot out the sky? are you aware how retarded you are?

By Andrew Adams on 2014 12 08 - 11:40:32

even other pilots dont trust glynn
http://pilotsfor911truth.org/forum/index.php?showtopic=22764

so fenton.. found any evidence yet that supports your claim that a plane hit the pentagon?

nothin but lies on this website then…

By Andrew Adams on 2014 12 08 - 12:05:50

glynn also believes a 757 hit the pentagon..
any proof dickhead?
might like to share it with these folk..
http://www.veteranstoday.com/2014/12/02/911-update-more-proof-no-boeing-757-hit-the-pentagon/

part time pilot and full time nefarious disinfo shill. along with josh anonymous.. would like to assure all these people - https://www.facebook.com/AustraliansAgainstChemtrails?ref=stream - and millions of others all around the world, that their concerns are baseless.. there is nothing to be concerned about.. as they wave their hand in front of you trying out their jedi mastery..

Ok, another graduate of the Peter Kusznir ” one of my obscenities is worth a thousand of your solid facts” school of debate. A few years ago I made the slightly joking comment that most chemtrail believers have room temperature IQs. Congratulations Einstein, you proved me wrong. You don’t quite manage room temperature. Enjoy life with the rest of the sweathogs, ace. But make a threat against flight crew and be assured life will get uncomfortable.

Andrew Adams wrote:

That’s because I notified him about this exchange, for obvious reasons.

Again: what is your evidence for what you call his “nefarious actions” and his being a “shill” ?

Hearsay is not evidence. Someone disagreeing with him (or you) is not evidence.

By Josh on 2014 12 08 - 20:59:26

josh anonymous.. obvious reasons? lol - wanker.. shoe size IQ glynn… doesnt have a shred of proof, nothing to back up his lies that a 757 hit the pentagon so he avoids the subject entirely.

his history of trolling the internet with regurgitations of government spin, “oh yes, a plane hit the pentagon” prove his nefariousness..
what a pair of pissants you circle jerkers are.

“But make a threat against flight crew and be assured life will get uncomfortable.”

gee dickhead, that sounds like a threat to me! - is that the best youve got?

By Andrew Adams on 2014 12 09 - 04:34:48

if there is ANYTHING here that i have said that could even faintly be construed as even the slightest threat, im sure you gormless smegmabrained arbiters of world truthiness would have already been crying to the police already..

so put up or shutup you shit eating cunts - any evidence of a 757 hitting the pentagon? anything? lol…. case closed

By Andrew Adams on 2014 12 09 - 04:39:39

Keep going Einstein. We aren’t in your league when it comes to proving the idiocy of your arguments. Who would want to be associated with that? No seriously… Keep going potty mouth! Lol.

By Michael Glynn on 2014 12 09 - 04:52:08

if you dont like that fact that all you have is lies being pointed out, maybe stop your lies?
theres a difference between not agreeing with someone, and being intolerant of lies.

you call this site TRUTHnews, yet all you do is lie. you lie about threats, you lie about everything. how low must your IQ be to think people would actually believe the shit that dribbles down your chin..

glynn says people concerned about the trails they see in the sky .. have room temperature IQ.. gee, thats a lot of credible people all over the world youre insulting there dickhead.. such hubris, or just such a microscopic intellect he actually believes it is only he who can set the internet free - like josh - that the governments are actually really concerned about each and every one of us and that the worldwide concern, is just water vapour, ..

you want to know a real measure of a stupid person, one who says a plane crashes into a building, and spends an inordinate amount of time saying it over and over all over the internet at every opportunity, but has nothing to back it up with. - and then! goes around calling other people dimwits.. pffffft.

By Andrew Adams on 2014 12 09 - 04:57:07

ohhhhhh potty mouth! ouch! - you yourself made a comment asking someone for proof, any proof, to support what they were saying, yet you cant offer any yourself.. hypocrite.

the use of colourful language offends you does it? good! now how about some proof ########?

By Andrew Adams on 2014 12 09 - 04:59:49

“We aren’t in your league when it comes to proving the idiocy of your arguments. Who would want to be associated with that?”

ummm.. i hate to point out the obvious.. but you make an argument that you fail to prove, you actually refuse to prove. that is your choice of association. tsk tsk tsk potty brain lol?

By Andrew Adams on 2014 12 09 - 05:04:53

“Mike Glynn, a committee member of the Australian and International Pilots Association, told the Associated Press he considers pilot suicide to be the most likely explanation for the disappearance, as was suspected in a SilkAir crash during a flight from Singapore to Jakarta in 1997 and an EgyptAir flight in 1999.”

RECLAIM AUSTRALIA IS DOOMED

Although I agree with many of their ideas, the forces reigned against RAM are too great, violent, statist and reactionary for them to remain a non-political, broad based, multi-ethnic, community protest group for much longer. The Left and their Antifa nihilist fellow travelers are already pushing them towards the extreme Right, by calling them racists and Islamophobes and so on. Whilst the extreme Right have aligned themselves with RAM. With fascists of the Left and Right pressuring them they will not be able to remain beyond the Left-Right divide and will inevitably move to the Right - the extreme Right. Which is already happening. A development which will alienate decent Australians of all ethnic backgrounds many of whom currently support them.

The RAM leadership have already established open alliances with the Patriotic Front (the ape in the photograph is a Patriot Front supporter at a recent Richmond demonstration) Australia First and Golden Dawn, a Greek neo-Nazi party. Members of these collectivist groups are currently attending RAM demonstrations all over Australia.

There is a real need in Australia to establish a political movement beyond the Left-Right divide and their vested interests, a movement that questions the current direction Australia is heading i.e. the direction the Left/Right and their extremes would like to take it; that questions the efficacy of state sponsored multiculturalism, as opposed to a proper, non-discriminatory immigration policy; that questions the validity of political correctness; that is politically neutral, anti-war and pro environment; that is opposed to all collectivists ideologies (fascisms of the Left and Right); that would dismantle the power pyramids of corporations and banks and their ability to impact on government; that would dissolve all anti-terror laws and all laws that impose on the rights and freedom of the individual and the people.

I second Keith’s assertion that Mike Holt from Restore Australia is very much a fake. He bangs on about Halaal being a scam and money maker for Islam (and no I don’t support Halaal whatsoever), but makes excuses for its counterpart Kosher as being a somehow legitimate. Double standards? When I confronted him about this fact he went off on a convoluted tirade about Israel being some sort of “Bastion of Democracy” in the middle east…Really!, I will leave that one up to the readers to decide on. I found that MH came across as disingenuous to say the least.

Without doubt, TNR is one of the best, if not the best alternative news source on the net. Which doesn’t mean Herewood is always right. His job, I believe, is to present the facts as he sees them as an objectively as possible, without fear or favor. For this, he has my respect and support. But I believe he needs to be careful and to think a little deeper about the problems of “racism,” in Australia. He has labelled the Reclaim Australia Movement as racist. I’m wondering if his objectivity is a little weak on this point, a little without foundation.

Of course all political movements have its fringe groups and individuals. We make a distinction between, for example, a Muslim and a fundamentalist Muslim (Islamist), and by so doing we don’t claim that all Muslims are blood thirsty fanatics. If its good for the Muslims, then its good for RAM, which is bound to attract a few lunatics and real racists. But to brand the entire movement as “racist” is wrong; it is the same ploy that is used by the mainstream media and its left-wing, establishment Marxist boot boys.

One of the first things I noticed when i attended a RAM rally recently were the amount of non-white people in attendance, including Aboriginals. In fact the main banner of RAM contains an Australian flag and an Aboriginal flag. Speakers at their rallies have included Jews, Arabs, Indians, Aboriginals, Chinese and so on. What does this tell you? Is this really a fascist-Nazi-racist movement whose stated aim are the eradication and exclusion of other cultures, in place of some sort of Aussie white Reich, or is this just propaganda that is being propagated by the left for their own political interests. Consequently, we all know where the culmination of their politics have led, historically speaking, which are to the imposition of terror and dictatorships.

We can be thankful for small mercies, in terms of the Left, which today mostly tends to attract collectivists, establishmentarians and the privileged sons and daughters of the upper bourgeoisie, who seems to share one thing in common, nativity….

Mike Holt from Restore Australia is very much a fake. He hasn’t even been citizen for but a few years. But, he makes out like he was born there. ALSO - this guy spent 30 years in Thailand working shady businesses. I would wager that his primary purpose in being an activist is that he wants to make money off selling merchandise.

good to see you putting out some new shows heraward

freely the banana girl is to a certain extent a troll, as is her boyfriend durian rider. they have been trolling the fitness community on youtube for some time… and yes they are extreme but they are also trolls. They use their trolling to spread their message. currently, another dude called vegangains is trolling the fitness community as well.

i am a vegetarian, and it was seeing this documentary on the pork industry that started me on the vegetarian path. for anyone interested, its pretty off the charts disturbing and its australian as well. its pretty much made by dudes breaking into pork farms and filming what they find

https://www.youtube.com/watch?v=KArL5YjaL5U

Would the world be better if people cared where their food came from? probably, they might then care about other things too

do you become a better person if you dont eat meat? i feel like a better person mainly because animals aren’t being hurt because of me. i dont feel humans have to eat meat really… or at least not much. How can you watch that documentary on pork, know that that is pretty much whats going on and turn a blind eye to it? I think its basic empathy and just saying well ‘i like bacon so yeah’ is in my opinion wrong and i can see freleys point of view to an extent. In my opinion, at least these people believe in something. i see my money as my vote, henceforth im ethical as to what i do with it. free range eggs became mainstream for exactly this reason… although im pretty sure woolies and coles lobbied the state to change the definition of the word ‘free range’ at some point. I dont eat beef because the amount of resources that go into growing a cow are pretty crazy. Think about how much grass that cow needs to eat before it is harvested and how much space it requires. think of how many vegies you could grow in the same space with the same amount of water. lamb? comon, think about what your doing here… but that being said i think most vegans are total loons. People like freeley should be advocating for the destruction of lions and tigers, as lions and tigers murder other animals in truly horrific style. if we humans are smart enough to not harm animals, then we should be stopping the animals that harm other animals from existing. Freeley also kills birds when she flies in aeroplanes so she is a hypocrite.

feminism is one of the biggest problems in society today and although there is some valid historical basis to it, the liberation of the human female from their biology is in my opinion largely a product of the technological advance of humans. sufferagettes where never machine gunned on the streets, unlike the men that where drafted and sent off to war to die just a few years earlier. as technology has advanced, women have advanced as well, however now its going way too far and is pretty blatantly anti male in many respects. i view feminism in its modern context as a tool of the social marxists that really isnt doing society a great deal of good at this time. its screwing up gender dynamics and is wrecking women and men for each other. i see it as low frequency, lowest common denominator idiocy, just like a lot of the the race baiting ‘is this racist’ stuff getting around that is being perpetuated pretty much as a distraction, divide and conquer strategy by the power elite. idiots love this kind of bicker and beef… it would be funny if it wasn’t so serious

anyway

I agree with steven friar. gods a maniac

good show… keep making them

Almost two months since the last broadcast! How the hell can you expect people to donate when you don’t broadcast? Looks like the ship of truth has sprung a leak. This broadcast has been part of my life almost since its inception…it is one of the few alternative news sources that hasn’t gone off the deep end, by dilution credible information with crap e.g. Fairdinkum Radio and Info Wars…Pittard started FR with some incredibly interesting material, but then he flipped…Today he sounds like a fundamentalist preacher, the Christian equivalent to a Fanatical Islamist. As an atheist, I think he’s really ###### up a potentially good show. As for Info Wars, all they would have to do to improve is dump Alex Jones, what a shit-for-brains. I reckon Jones and Pittard are allowed to proliferate, because they’re so stupid and harmless. I suppose they have some entertainment value, and along with David Icke are living examples of how low the alternative media has sunk. Truth News Radio is, or should I say was, way ahead of them all ahead of them all in terms of credibility How sad that its come to this.
