Engineering the planet's weather and climate is a highly controversial idea. That's why we need experiments, the group say, and they want the first to start in two years' time.
Last week, the group published a 'road map' of proposals for how real-world experiments might be carried out...The second, and most detailed, devised by John Dykema of Harvard University, would explore the effects of injecting sulphur-containing substances at an altitude of 20 kilometres – the lower reaches of the boundary with outer space.
...So far, all geoengineering work has been in the lab or based on computer models. 'Modelling and lab experiments are critical,' says Dykema. 'But to understand the intricate chemistry people are concerned about, the only way to find out is in the atmosphere, where you have the right flux of solar radiation, the right mix of chemical species and the real dynamics of aerosol particle interactions in gas, liquid and solid phases.'
'The proposed experiments are quite small scale, and the environmental consequences are likely to be negligible compared with a lot of human activity we already take for granted,' says co-author Doug MacMartin of the California Institute of Technology in Pasadena.
Dykema's experiment, for example, involves releasing just a kilogram of sulphur, the same amount as emitted in just 1 minute by a standard commercial jet.

Thank you for this sober look at what is happening in the sky.
Too many on ATS, ESPECIALLY in this forum, seem to jump to conclusions and suffer from extreme bias, practically shouting that nothing is happening.
Well, that is not how true science and research works. Start unbiased. Pick an hypotheses, and research and investigate it.
Yet all we hear out of the government on this subject is crickets, kind of like the UFO issue.
Many of us older than 30 or so remember how the skies used to be when we were younger, contrails would stick around for less than a minute or so. Yes, there used to be persistent contrails, but they were labelled an extremely rare phenomenon.
Now, however, on somedays every contrail laid down stays for an hour or longer.
Have the laws of physics and chemistry changed?
Sure, there are more planes in the sky, but that only explains the number of contrails we see, and does nothing to explain why they persist up to 100 to 1000 times longer than in the 70's and 80's.
Well, again, that may explain why a contrail may develop more quickly, but the process of a contrail vanishing is still the same as it was pre-2000, basic sublimation, so I don't see the "claimed" science by some on here of how cooler jet exhaust causes a hugely delayed sublimation.

A lot of things could happen. With a finite amount of time to spend, you see this as a priority one, existential threat? Based on evidence I've seen, I must disagree.
If they are spraying for whatever reason, why would they do it during the day when people can easily see it?
Why not just cover the sky at night?

Also, I don't know why some debunkers are obsessed with it, they literally have thousands of posts in this forum. (oh wait, I do know why)

Have you considered that there is more available pollution in the stratosphere now vs. 30 years ago? The persistence of an ice cloud should be dependent on how it's nucleated. In other words, an ice crystal nucleated on a grain of dust or soot will be much bigger and more persistent than one nucleated on S02 molecule.

Oh, they do. I see moon chemtrails all the time.
Maintaining the global Sky as a holographic image is a 24/hour process.
And keeping this going as something close to the truth must take even longer.

Okay one question for you...
How is this related to the chemtrail conspiracy theories that your defending?
originally posted by: Petros312
The notion that geoengineering is distinct and discrete from the historical activities of weather modification and control, contrail formation and the study of cirrus clouds on solar radiation management, particularly given aerosol sprays and jet aircraft are indeed involved in all these activities in some manner, is an illusion reinforced by the social reality asserting itself to stygmatize anyone suspected of being a "chemtrail conspiracy theorist." People being branded with the label "chemtrail conspiracy theorists" is manifested first by the question many of them ask, "What are they spraying in the sky?" Debunkers on websites like ATS then single out the ones who make errors about what is a contrail, why does it form, what makes a persistent contrail, etc., and supposedly the concern about "What are they spraying in the sky" becomes completely unwarranted. The quick shift from evidence such as the history of weather modification and its associated experimentation, the history of open air testing done in the US in civilian populations, the desire for the US military to own the sky and control weather for "DOD purposes," the outlined plans of the Spice experiment revealed by John Dykema in the UK, the talk of people like David Keith and his associate about releasing sulphur into the stratosphere as an aerosol as the first of experiements to study the effects --all of this disappears in the good name of geoengineering as if it's nothing but a pure science, and that's exactly what proponents of geoengineering like Bill Gates want. They know how to manufacture consent through social reality, and I examined the process in my prior post in defense of chemtrail conspiracy theorists.
I realize that the above question will be asked repeatedly, which is why I specifically addressed it right here (now with some highlights to help show where):
