    It’s not cost effective to save humanity. Stock prices would crash.

      You are missing the point, because we need to do that anyway.
      The idea is to prevent things from getting worse in the meantime.
      Replacing fossil fuels take time no matter how much we invest.

        ok but you just know corporations are going to use this as an excuse to keep using fossil fuels. like to them this is basically carte blanche to keep the status quo and block green energy from happening even harder. “oh hurdur har har we found a solution to climate change and it’s dumping diamonds in the atmosphere, no need to pay for green energy anymore haha” type shit

          Corporations follow the law, the only way to solove this is to have the laws required.

              Oh please, of course they don’t always, but the ones that don’t are generally forced to by oversight.
              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.

        Thanks, hadn’t seen that before. I wonder how things like “eat less beef” fit into that chart, or of that’s part of the $0 premium.

    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.

        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.

        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.

                I just wonder why not use sapphire dust instead. Doesn’t it reflect sunlight almost identically?

                Not quite minuscule, for every ton of jet fuel burned, 2 tons of oxygen is needed, to take that in, about 3-4 ton of atmospheric air goes through the combustion, the volume of that air is quite a lot, and is only sustained because oxygen is constantly renewed. The diamonds will not have self sustained renewal and will be burned up pretty quickly.
                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?

    Isn’t this very similar to the annuki and the Sumerian history. Where these aliens came to earth to mine gold to take it back to their planet and use it to save their atmosphere.

      Elon musk’s kids should be made an example of when reclamation comes around.

      They’re being brought up thinking they can live like gods. How unfortunate would it be if they actually had to live like the rest of us…

    “Scientists say…”
    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.

    Of all the aerosols they could think about!

    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.

    Does it have to be diamonds? Could we maybe use the ashes of billionaires instead?
