    “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.

    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.

    Let’s throw more carbon to the air, what could go wrong. Is not like it will get to our lungs and destroy everything from the inside.

    That amount sounds like total bullshit. Diamonds can be manufactured and once that is done at scale, it won’t be all that expensive. Even at $10000 a ton, five million tonnes would cost just 50 billion.

      Firstly, it’s 5 million tonnes per year. For 65 years. Secondly, the cost is for a 65 year SAI program, including developing the tech and running the missions. Thirdly, this is all explained in TFA or the links therein.

      That number is for doing it anually for 65 years. It lists roughly 18 billion per year for the cost.

      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 https://www.diamondtech.com/products/categories/diamond_powder_price_list.html

      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

      These are not good ideas. Remember that global warming is just an overarching effect of pollution which we will still have. What diamond dust pollution effects will be, no one knows, but I doubt we want to find out.

        The fossil fuel oligarchy would prefer to give all mammals on Earth emphysema than stop burning fossils, and do it for 10x the price.

    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.

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

    Yes, let’s just have everyone on Earth breathe in diamond dust all day every day. There’s no way that could be bad for our health.

      just wear masks for a few decades, potentially respirators, and probably add whole house air filtration if you want to take it off at night.

      There’s never been a case of something having different behavior or health effects just because of a tiny chemical difference (trans fat) or size difference (micro plastics), what’s the worst that could happen?

      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 are going to use this as an excuse to keep using fossil fuels.

          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.
