Limitations of Climate Engineering Efficacy by different types of RADiation MANagement

二氧化碳减排、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，我们挑战了这一假设，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，研究了太阳辐射管理（SRM）的局限性。这是第一次全面尝试定量预测这两个最常讨论的SRM方案的局限性。这将包括首次同时量化SAI和MCB的局限性。我们推测，这些限制可能会对法律和政治影响产生深远影响，这些影响将减缓、适应和气候工程措施（包括气候公平政治）联系起来并按顺序排列。先进的大气数值模式包括详细的气溶胶和云微物理，用于确定两种SRM技术的物理极限。然后，这些结果将成为SPP内部综合评估不同的法律环境行政治理制度以及二氧化碳减缓、适应和气候工程之间相互作用的基础。

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.
