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.

World GDP: $105.4 trillion USD

    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.

    “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.
