Abstract

Solar geoengineering (SG) solutions have many advantages compared to the difficulty of carbon removal and reduction (CRR): SG produces fast results; is shown here to have much higher efficiency than CRR, is not related to fossil fuel legislation, is something we all can participate in brightening the Earth with cool roofs, and roads, and this assessment illustrates how SG is feasible with the help of technology. Methods detailed previously for SG requirements have been an issue primarily because of overwhelming goals and concerns about climate circulation. In this paper, higher feasibility is provided for solar geoengineering applications by focusing on estimates to stop annual increases in global warming rather than full mitigation. Annual SG area requirements are generally fifty times less compared to the challenge of full mitigation. Results indicate that AI drone technology is likely important in Earth brightening and may be key in meeting annual Earth brightening mitigation goals. Furthermore, results also indicate much higher feasibility for L1 space shading compared to prior literature estimates. However stratosphere injections appear challenging in the annual approach. To address yearly global warming, a multiple mitigation approach is suggested. Therefore, results recommend focusing on Earth brightening and space shading which appear reasonably feasible.
