You know- things like the infrastructure that would be needed to ship stacks of coal ash to military airports- sprayers on planes- well- actually anything would be a start?

Do you live inside a military base?

It doesn't matter where I live.
It is your job to back up your claim.
Why do you keep failing to even try to do so?

Condensation without freezing=condensation aerosol (not exothermic)

Water vapor condensing into cloud droplets is, by definition, an exothermic process. The water vapor gives up heat to the cooler air around it until it becomes cold enough to condense.

Condensation with freezing="cloud in a bottle" (exothermic)

I don't think the cloud in a bottle experiment gets cold enough to freeze the water vapor contained within it.

Forgive my ignorance, but is vapor phase photooxidation a exothermic reaction?

[alancalverd]

Most oxidations are exothermic.

It depends on the circumstances (mainly: what are you oxidising?).
But it has nothing to do with the topic.

And, BTW, any progress on the evidence?

Most oxidations are exothermic.

Exactly half of oxidations are exothermic.
All reactions are (in principle) reversible.
A reaction that is exothermic in on direction is endothermic in the other.
It's still nothing to do with the topic.

Understanding if artificial cloud seeding is produced intentionally or from the deliberate injections of reflective particulates is critical to understand why solar geoengineering activity is a form of air pollution.

Still not found any evidence then?
And the energetics of reactions like that are rather small compared to the energetics of weather.

I can't think of a single endothermic oxidation! Possibly due to senility, but I'd be grateful for an example.

The formation of some nitrogen oxides are endothermic.

OK, consider iron being oxidised by a copper sulphate solution.
Iron is oxidised and coper(II) ions are reduced.
The reaction in that directiuon is exothermic.
Now consider the reaction in the opposite direction where copper is oxidised by iron(II) sulphate to produce iron  and copper sulphate.
That reaction must be endothermic.

That reaction doesn't go very far, but you can calculate the extent to which it happens and that extent is not zero.


As I said, since all reactions are reversible, any oxidation  is reversible- but even in the "other direction" it's still an oxidation.
And in one direction or the other, it must be endothermic.

This still has nothing to do with the topic.

Who cares.  That orange skinned clown will never get anywhere near the white house, thankfully... 

Mind repeating that ?  -

Solar geoengineering is unilateral scientific radicalisation with serious risks for human health and the environment. Conventional air traffic creates no chemtrails. There's no reason to hide or disguise the truth as climate change or global warming. The evidence of systemic disinformation and propaganda on geoengineering activity is brainwashing and manipulation of atmospheric oxygen-ozone levels.

[MayoFlyFarmer]

I'm guessing Trump is a huge fan of chemtrails.  If it weren't for crazy conspiracies like this, the radio shows from which his campign support swelled would have anything to discuss on a daily basis and would exist. If that were the case, he never would have gotten a sniff at the White house.

Yeah. My thoughts exactly. Pretending solar geoengineering research is new is also a fake news.

Abstract

The large burden of sulfate aerosols injected into the stratosphere by the eruption of Mount Pinatubo in 1991 cooled Earth and enhanced the destruction of polar ozone in the subsequent few years. The continuous injection of sulfur into the stratosphere has been suggested as a “geoengineering” scheme to counteract global warming. We use an empirical relationship between ozone depletion and chlorine activation to estimate how this approach might influence polar ozone. An injection of sulfur large enough to compensate for surface warming caused by the doubling of atmospheric CO2 would strongly increase the extent of Arctic ozone depletion during the present century for cold winters and would cause a considerable delay, between 30 and 70 years, in the expected recovery of the Antarctic ozone hole.

Are you trolling, or do you really not understand the difference between

"... has been suggested as a “geoengineering” scheme..."
and anything like evidence that geoengineering is actually being done?

Solar geoengineering is more clandestine than a experimental scale research.
The only thing which you need to realize is that Trump will not stop chemtrails.
Wake up.

I'm awake.
I'm waiting for you to provide some sort of evidence that chemtrails exist.

Are you ever going to do so?
