Scientists say sprinkling diamond dust into the sky could offset almost all of climate change so far — but it'll cost $175 trillion
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.Sascha Pare (Live Science)

No chance at all of a basically indestructible material not being destructed if absorbed by lungs (or gills) and leading to some disease. You don't need to check. There's no way this could go wrong.
Or, rather... I believe lead is cheaper... Given how much people like to use it, maybe it's a better option.

Instead, the world has a few mechanisms that will make asbestos harmless after a few generations. Not so much for diamonds.

But besides that, I think you are greatly underestimating the cost of the diamonds. Synthetic ones are way cheaper than natural ones, yes, but there's a lot of room between "natural diamond expensive" and "actually cheap". Going by these prices diamondtech.com/products/categ…
It's $2.5 million per tonne. I assume you could get a cheaper price per weight if you're buying five million tonnes of anything, but it's still two orders of magnitude more expensive than you are guessing

in reply to itslilith • • •Yes I kn ow they generally get off easy, but then oversight is increased and if it continues, the penalties increase, until ultimately it will be forced to shut down if illegal activities continue.
So yes generally cooperations do follow the law.

The main reason they looked at diamond this time is because it's very clump resistant, which is a positive for heat deflection.

in reply to Buffalox • • •CO is not a significant greenhouse gas. (And N20 is..)
Are diamond particulates likely to burn if they're dispersed in the atmosphere?
Buffalox
in reply to naught101 • • •Actually yes, if they enter the engine of a plane they will burn.

in reply to naught101 • • •Also being an aerosol increases surface and potential chemical reactions by a magnitude of maybe a billion per unit, so although we consider diamonds to be very stable in their normal form, a diamond aerosol is obviously much less so, and UV light refracted could accelerate break down of the diamond aerosol, into free carbon, which will create carbon gasses. I bet researchers have considered this, but I see no numbers for it?

in reply to febra • • •It's not really any different than usual dust, other than it is even more likely to scratch your phone (oh no!). The surprising thing is the bullshit price number, I'm sure it's some brain-dead economist looking at the point-price for diamond and with great effort making a single multiplication.
Edit: The study does note industrial diamond manufacturing, but doesn't go into detail on why it's so expensive for diamond powder, other than saying "it would require much more industrial diamond than is currently produced".... Which is just.... Empty? Considering industry would change to account for such a drastic rise in demand.

All of them, are you sure?
Geoengineering schemes are not agreed upon by many scientists. There are several types of geoengineering "solutions" and no agreement on any, just suggestions.
