Abstract

Solar radiation management (SRM) is a geoengineering strategy designed to combat global warming by reflecting sunlight away from Earth, thereby reducing solar heating. While SRM has the potential to lower global temperatures, it's distinct from addressing the root cause of climate change: greenhouse gas emissions. This study utilized system dynamics (SD) modeling to illustrate the relationships between various factors, including Solar Radiation Utilization. Simulation results for Spatial Position, Protection Principles, and Solar Radiation Utilization ultimately demonstrate a gradual increase in Global Warming Mitigation. Our study indicates that infrared-centric solar shielding effectively reduces global warming. We recognize the inherent uncertainties in the precise position and angle of such shielding, so we conducted simulations across two distinct spatial configurations. The comparative statistics from these simulations reveal that Case 2 resulted in a greater maximum value for global warming mitigation. This finding clearly shows the impact that the placement of solar shielding has on its overall effectiveness. Further research could explore optimizing this placement for even more substantial results.
