But none of this actually addresses the "proof enough for me". That seems to be his bottleneck, only six miles away but still a complete mystery.
For a solution to that, he will need to begin acquainting himself by actual physical observation of the contrails he sees.
Chedca, you need to identify the planes you see. Chedca, here were my thoughts o this over two years ago. The people who seem to have influenced you haven't taken the suggestions. Will you?

I will take a close look at this thread in the near future, thank you honestly for considering the posts I've made and explaining things to me.

Yes, I admitted to being more open to considering the possibility for aerosol testing just because I feel like the contrails I observe can be abnormal. Don't let that stop you from objectively considering the potential reality of this essay when it urgently recommends testing climate mitigation techniques, and in turn, the sort of techniques that have been considered, the date it was published, and the subsequent research done in the field of stratospheric aerosol spraying. Of course, keeping in mind the geo-political factors that would keep real life testing of this mitigation technique away from public view.

"This study describes an approach to cooling the planet, which goes back to the mid-1970s, when Budyko (1974) suggested that, if global warming
ever became a serious threat, we could counter it with airplane flights in the stratosphere, burning sulphur to make aerosols that would reflect sunlight away. The aerosols would increase the planetary albedo and cool the planet, ameliorating some (but as discussed below, not all) of the effects of increasing CO2 concentrations."

Nowhere in the paper is albedo or geo-engineering mentioned. Their cloud chamber experiments were designed to take a closer look at natural ice nucleation processes with compounds that mimic a certain class of natural organic aerosols, not for the purpose of geo-engineering.

"Pre-activation (of aerosol ingredients) must be considered for the correct interpretation of experimental results on the heterogenous ice nucleation ability of glassy aerosol particles and may provide a mechanism of producing a population of extremely efficient ice nuclei in the upper troposphere." Is a quote from ;http://www.atmos-chem-phys.net/12/8589/2012/acp-12-8589-2012.pdf Karlsruhe Institute of Technology, Institute for Meteorology and Climate Research, Karlsruhe, Germany

The term glassy, I believe is used, to describe the particles ability to reflect light.

Sorely, can you suggest why they would be trying to form ice in clouds at the upper troposphere? What sort of development does this research lend itself to besides albedo enhancement?


"Progress in the understanding of the complicated earth climate system is generally slow." I believe my interpretation of this is accurate, I will try and explain; because stratospheric sulfur injections threaten the ozone layer, it is hard to tell if the damage done to the ozone will counteract any global cooling achieved, by letting more solar rays through to the surface of the earth. As the previous sentence reads; "The chances of unexpected climate effects should not be underrated, as clearly shown by the sudden and unpredicted development of the antarctic ozone hole"

"The aerosols also serve as surfaces for heterogeneous chemistry resulting in increased ozone depletion."

No it doesn't. Not as the current meme; long white lines being issued by aircraft that are generally identified as commercial or military flights. All of those flights are operating either well below the stratosphere or not in an area where SAG has been mooted as desirable. I.e Equatorial regions.

The aircraft photographed are too fast moving for a balloon and not fast enough for a shell. The amount of material issued by the aircraft far exceeds the weight of material able to be carried by either aircraft, shell or any mooted balloon.

Don't get me wrong, TWCobra, we are talking about aircraft here. Consider the Aerosol Injection Scenarios proposed in this article;
http://rsta.royalsocietypublishing.org/content/366/1882/4007.full

"Two rather conservative injection scenarios are evaluated,(...) (i) insertion of a primary aerosol, such as fine sulphate particles, using an injector mounted aboard an aircraft platform cruising in the lower stratosphere and (ii) sulphur-enhanced fuel additives employed to emit aerosol precursors in a jet engine exhaust stream."

"Enhancing aircraft fuel with added sulphur compounds (H2S, Sn) could increase the particle mass in a jet wake."

"If we imagine enhanced jet fuel sulphur contents of 5 per cent by weight (10–100 times current amounts) for geoengineering purposes, then the annual consumption of approximately 50 Tg of such fuel during stratospheric flight (approx. half the amount used by current commercial aviation) could emit up to 2.5 Tg of sulphur that would eventually generate roughly 10 Tg of sulphate aerosol. (...) This number, uniformly dispersed over a 10-km thick layer from 15 to 25 km, yields an average concentration of approximately 1×103 cm−3 with a particle radius of roughly 0.06 μm; in other words, an ideal geoengineered solar shield."

TWCobra, these scientists are keen on the idea that it is possible to reverse climate change through enhancing the sulfur content of commercial airline fuel , combine that with an urgency for employing / determining the effectiveness of a GW mitigation strategy [1] , don't you think they would have put considerable pressure on politicians to approve such research, on an entirely moral or empirical platform?
Consider the words in this editorial;

"(...) For this reason it follows that the artificial release of sulfate aerosols is a commitment of at least several hundred years. A cessation of the intentional sulfate emission of 1–2 Mton/year will in a short period of time lead to a return to the unfavorable conditions and a renewed warming of the planet."
"I leave it to the reader to ponder over the feasibility to undertake a joint experiment to control the Earth's climate, which may have to last for the length of perhaps a millennium. And the fact that the efforts will be of little use unless we continue the aerosol emoission without interruptions. And, finally, as the experiment is conducted we will not be able to convincingly demonstrate that it actually works unless we have collected validation data for at least several decades towards the backround of natural climate variability."
