Stratospheric solar geoengineering without ozone loss PNASCalcium carbonate Wikipedia

Injection of calcite or limestone particles rather than sulfuric acid could counter ozone loss by neutralizing acids resulting from anthropogenic emissions acids that contribute to the chemical cycles that destroy stratospheric ozone Calcite aerosol geoengineering may cool the planet while simultaneously repairing the ozone layerCalcium carbonate is a chemical compound with the formula Ca CO 3 It is a common substance found in rocks as the minerals calcite and aragonite most notably as limestone which is a type of sedimentary rock consisting mainly of calcite and is the main component of pearls and the shells of marine organisms snails and eggs
