CO2 abatement, adaptation and climate engineering (CE) are widely understood to be three independent approaches to addressing harmful climate change. In this project, we challenge this assumption by examining the limitations of solar radiation management (SRM) by means of Sulfate Aerosol Injection (SAI) and Marine Cloud Brightening (MCB) as instruments to lower global/regional temperatures. This is the first comprehensive attempt to quantitatively predict the limitations of these two most frequently discussed SRM schemes. This will include for the first time the quantification of the limitations of SAI and MCB in parallel. We surmise that these limitations are likely to have a profound impact on legal and political effects that link and sequence mitigation, adaptation and climate engineering measures including the politics of climate equity. Advanced atmospheric numerical models encompassing detailed aerosol and cloud microphysics are used to ascertain the physical limits of both SRM techniques. These results will then form the foundation within the SPP for an integrated assessment of different legal CE governance regimes and the interactions between CO2 mitigation, adaptation and climate engineering.

CO2减排、适应和气候工程（CE）被广泛认为是应对有害气候变化的三种独立方法。在这个项目中，我们通过研究太阳辐射管理（SRM）的局限性，通过硫酸盐气溶胶注入（SAI）和海洋云增亮（MCB）作为降低全球/区域温度的工具来挑战这一假设。这是第一次全面尝试定量预测这两个最经常讨论的SRM计划的局限性。这将包括首次并行量化SAI和MCB的局限性。我们认为，这些限制可能会对将减缓、适应和气候工程措施（包括气候公平政治）联系起来并排序的法律的和政治效果产生深远影响。先进的大气数值模式，包括详细的气溶胶和云微物理用于确定两个SRM技术的物理限制。然后，这些结果将在SPP内形成对不同的法律的CE治理制度以及CO2减缓、适应和气候工程之间的相互作用进行综合评估的基础。
