BOTH sides have the burden of evidence to actually investigate what is in the air.

Here is one such paper: www.aero-net.info...

I mean this is basic science we're talking about here. Water particles freezing in cold saturated air. Not some kind of long shot antigravity science or anything, just basic stuff.
Contrails trigger contrail cirrus with far larger coverage than observed for line-shaped contrails, but still unknown radiative properties. Some model simulations indicate an impact of particles and particle precursors emitted from aircraft engines on cirrus cloud properties. However, the magnitude of this effect cannot be assessed.
The expansionist logic of airlines and airports assumes that the air around and above us has an infinitely absorptive capacity and can tolerate any pollution. We used to think that about rivers. It isn't true, in either case. Industries that pollute rivers have been forced to change, to clean up. The people who worry about pollution from planes (noise pollution, trails of fuel waste raining down) are no longer Luddite crackpots.

The only thing worth responding to is this:
Yes, and I'm sure you understand every bit of the "basic science" contained in Schumann's 2005 report (your link says "in press," which means the same article may not be one that appears in a peer reviewed journal). Note this is not the 70 years of research that you suggested exists above. I also distrust your accuracy that Schumann's analysis on contrails in general can be best summed up in your words:

--So I don't know who you think you're fooling about "basic science," as if all is simple and well-known.
More importantly, you continue to confound what is actually in the sky at any given time and on any given day with research that is only a general explanation of a phenomenon.
But to be fair, I'll paraphrase the gist of what you're driving at: Debunkers want to continue stigmatizing all chemtrailers to reinforce the social reality and make it appear the reason a segment of the population is concerned about jet aircraft activity is for nothing but the fear of "a world wide network of conspiring agencies and companies."
Never mind the many issues people labelled "chemtrail conspiracy theorists" are actually concerned about (distrust of the government, reckless military activity, unethical experiments, stigmatization of a segment of the population by establishing social reality, apathy over pollution and environmental issues, solar radiation management, the likely effect of capitalism on geoengineering, etc.).
Let's just keep doing is continue our small talk about what is a "normal" contrail, what is a persistent contrail (i.e., it's only normal), and why persistent contrails sometimes turn into cirrus clouds (a "normal" phenomenon, given the bizarre notion that human beings are supposed to be making clouds in the sky).
I'll leave you with an interesting quote, which I'm sure you will not understand within the context of a thread about chemtrail conspiracy theorists:
The expansionist logic of airlines and airports assumes that the air around and above us has an infinitely absorptive capacity and can tolerate any pollution. We used to think that about rivers. It isn't true, in either case. Industries that pollute rivers have been forced to change, to clean up.

In all of your many and lengthy posts defending chemtrail conspiracists, you don't actually talk about chemtrails at all...
Is your lack of response an indicator that you don't actually know?

.....stigmatised beyond belief for their concern that the jet activity manifested both with and without contrails is a form of pollution obliterating the blue sky.
It is not known if some of this activity is a) intentional for the purposes of solar radiation management or experimentation, b) is an effect of unregulated air traffic, c) is research on how aerosols can be dispersed for geoengineering purposes, d) (given a history of open air testing in the USA without the public's consent) is accompanied by some kind of aerosol spray that has nothing to do with the actual persistent contrail but is still potentially harmful, or all the above. Do I know if a,b,c, or d are the case based on solid evidence? No. But guess what? Neither do all those debunkers out there who keep encouraging all of us with bad science, logical fallacies, and irrelevant info-based "evidence" to uncritically and firmly conclude all jet activity and subsequent appearance of contrails is "normal."

That is an entirely reasonable concern, you and I know it. Indeed it's a point I've made several times myself. We also both know that is not what chemtrail conspiracy is about AT ALL. Pretending otherwise is merely a devious tactic.
--"Chemtrailer" has become a catch-all term. Consider the diversity of the claims all being lumped into "chemtrail conspiracy theory" and you see everything from mind control to respiratory illness. The people accused of being unscientific and unreasonable if not flat out delusional include the people who claim that the EPA needs to regulate air traffic for reasons that include jet engine exhaust and contrail formation. The contrails may not be the source of the air pollution (depends on what you mean by "pollution"), but they are still a marker for the jet exhaust released that research supports is the cause of more respiratory illness and deaths.

ETA, please give an example of a logical fallacy or of bad science offered as an explanation of contrails and why it is bad, so I can see what you mean.
originally posted by: network dudeSince we have all been here for a while, discussing the same things, could you please explain why you are convinced spraying is taking place there?
I see an awful lot of people from CA talking about chemtrails.
On the East coast where I live, there just doesn't seem to be that many trails to speak of. I don't think I have ever seen a day where the entire sky was covered.

You can't prove nothing is happening out here because you're not here, and that was my point, and it still stands. ~$heopleNation

But there's no point to meeting these "demands" of yours; it's practically a pedantic exercise at this point. You're not saying anything new here.
