Do space launches warm or cool the surface temperature (admittedly, for a little bit)? This BBC article presents it as an emerging climate problem but also says
If the amount of black carbon expelled into the atmosphere reach 30 gigagrams a year, or even 100, then there will be some cooling of the surface of the planet under this black carbon umbrella.
So what's the whole debate all about then? Isn't it a good thing that it counteracts the warming effect to some degree?
