Optimal Solar Geoengineering for Managing the Tipping Risk of Coral Reef Ecosystems 1: Beijing Institute of Technology, China, People's Republic of; 2: The Ohio State University Solar geoengineering, also known as Solar Radiation Modification (SRM), provides rapid cooling that can reduce temperature-driven climate tipping point (CTP) risks, but it may simultaneously trigger carbon-driven CTPs by weakening incentives for emissions abatement. We extend the Dynamic Integrated Climate-Economy Model (DICE-2023) into a stochastic framework to examine the optimal mix of abatement and SRM under the collapse risk of coral reef ecosystems, an urgent CTP jointly driven by warming and acidification. The results show that: (1) without SRM, immediate and deep abatement is required to have a chance for preventing the ecosystems’ collapse, while abatement alone may still fail when ecosystems are highly sensitive to acidification; (2) combining abatement with SRM prevents the collapse while lowering considerable abatement burdens. These findings underscore the need to distinguish different drivers of CTPs in climate decision-making: abatement is required to address their root causes, while SRM is crucial for mitigating urgent risks. | |
