Abstract

Given increasing evidence that limiting global mean temperature to the Paris Agreement targets is unlikely, additional interventions such as Solar Radiation Modification (SRM), in addition to substantial emissions reductions, may be required to mitigate the risk of severe climate impacts. Among the various proposed SRM strategies, studies suggest that Stratospheric Aerosol Injection (SAI) could provide relatively uniform global cooling. However, major scientific gaps persist, and issues of equity, justice, and governance impede progress toward the inclusive research and public engagement necessary for science-informed discourse and decision-making. Here we present the SAI Simulator version 1.0, a browser-based tool that enables the public, media, and policymakers to explore some of the global and regional climate impacts of various SAI deployment scenarios compared to continued warming, based on state-of-the-art climate modeling results. This expanded access to SAI simulation data and scenario design capabilities fosters broader and more inclusive engagement with SAI research.
