Please don't buy into geoengineering. We need to repair our relationship to nature through rewilding. We should be changing the way we live, giving up large monoculture crop that goes toward animal husbandry and rewilding the planet to sequester carbon emissions. We are in this situation because our ancestors changed the land and the wildlife so radically in our attempts to industrialize. We overfished, killed whales, ran large predators into extinction, removed most old growth forest among many other things. Humans have tried geoengineering before, we dam rivers, flood planes, dig canals, level the earth and introduce species where they are not native, among large chemical, mineral, metal and other injections to the ground, sky and water. The climate models see carbon sequestration, SRM and geoengineering as attractive options because it lets us continue business as usual. We do need rapid change, of the way we live and with our relationship with the earth.
