Keith, David W.; et al. (2016): Stratospheric solar geoengineering without ozone loss

Keith, David W.; Weisenstein, Debra K.; Dykema, John A.; Keutsch, Frank N. (2016): Stratospheric solar geoengineering without ozone loss. In Proc Natl Acad Sci USA, p. 201615572–201615572. DOI 10.1073/pnas.1615572113.

"The combination of emissions cuts and solar geoengineering could reduce climate risks in ways that cannot be achieved by emissions cuts alone: It could keep Earth under the 1.5-degree mark agreed at Paris, and it might stop sea level rise this century. However, this promise comes with many risks. Injection of sulfuric acid into the stratosphere, for example, would damage the ozone layer. 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 layer."
