Spacecrafts burning in the upper atmosphere: what consequences on climate?

I’m guessing negligible impact compared to the act of sending them up there.
@SorteKanin the problem is not with air pollution, but only with specific pollution at the stratospheric level. It is here that some reactions can be created between the residues of satellite combustion and some gases and some nebular structures which can have a paroxysmal impact on the Earth’s climate
There can’t be more than a couple of thousand tons of satellites up there considering how expensive it is to launch stuff into orbit.
It’s negligible compared to the amount of space dust that enters the atmosphere and burns up every day.
