I had never heard of this so I googled around a bit. Thanks for bringing it up. It looks like an interesting area of active research. Apparently one of the promising minerals for sequestration is olivine, which, by some galactic irony, is largely sourced in the oil-producing nation of Norway.
Accelerated weathering is our first best hope of lowering CO2 in the atmosphere.
Weathering is the conversion of carbonates and CO2 to form bicarbonates.
Grinding and aerosolizing limestone and other similar minerals hasn’t been tried very much.
Unlike with anything plant-based, once CO2 goes through this reaction, it stays.
In a few billion years, it’ll cause the extinction of life on Earth, but that’s a problem we can take our time to figure out.
