I include this link, which pretty thoroughly covers some of the proposals for geoengineering. Notice how these proposals suffer from three different problems. One, some are very expensive/energy intensive, Two, some would not address the problem of current CO2 in air and thus ocean acidification and three, some have dire associated risks.

We may try anyway though if the climate gets too bizarre. But I do not have the expertise to make too many comments other than my own layman opinion.

There is no way currently in which we can chemically scrub or recycle the greenhouse gases from the atmosphere. This means that the planet is slowly gaining heat from the sun, and the overall heat-loss to space is being reduced, or at least, cannot keep up. Slowly the oceans are storing it.
So, we can reduce the incident solar radiation on the surface of the planet. By launching enough reflective metal/ceramic dust in orbit, eventually significant (~+10%) radiation could be diverted and this would allow for the planet to quickly "bleed-off" heat, before the dust fell back to Earth. Some draw-backs are that, the further away, the more dust would be required, so this would essentially prevent satellites from orbiting w/o being armored in LEO.
This would be expensive, but I think its doable. In fact, it appears that "chemtrails" already achieve this to a degree.
Another one, would be to assemble a gigantic solar shade at the Sun-Earth L1 point. I think this would be much more challenging technologically and economically. But if possible, the shade could be used to adjust incident solar radiation in order to fix the incoming-outgoing heat equation.

But I think this kind of thing does show just how utterly desperate people who have been following developments as they unfold are feeling.

I remember people talking about using them to stop the oil spill in the gulf a few years ago. Just stupid (and of course if these idiots had any power...dangerous!).
Don't know quite what the psychology is there.
As to using planes, you have to be careful. My impression is that, generally, the higher the clouds, the more likely that they will block more outgoing radiation than they block in coming (but someone should check me on that).
In any case, unintended consequences are pretty much certain to ensue, no matter what.
