The geoengineering scheme, known as stratospheric aerosol injection, would not be cheap, but scientists say it could buy us some time until we reach net-zero carbon.
I don’t get it, why wouldn’t sapphire dust work? Isn’t that dirt cheap to make? And it’s carbon free!
Seems illogical to add carbon in the form of diamond, to a problem that is mostly caused by carbon?
The carbon isn’t the problem, it’s the CO2 molecule. I would be really curious if solid carbon in diamond form is able to react with ozone in the atmosphere to make CO2, or if it would be inert, or if it would do something else.
It’s also Methane and CO, gasses that also contain carbon. I know diamond is pretty stable, but it does burn, and then it creates the gasses we try to avoid.

CO is not a significant greenhouse gas. (And N20 is…)
Are diamond particulates likely to burn if they’re dispersed in the atmosphere?
Actually yes, if they enter the engine of a plane they will burn.
True. That would be a minescule fraction of what’s there though…
I just wonder why not use sapphire dust instead. Doesn’t it reflect sunlight almost identically?
No reactions, just reflections. The premise is “bounce the heat before it can be trapped.”
The main reason they looked at diamond this time is because it’s very clump resistant, which is a positive for heat deflection.
