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.

二氧化碳减少，适应和气候工程（CE）被广泛理解为解决有害气候变化的三种独立方法。在该项目中，我们通过通过硫酸盐气溶胶注入（SAI）和海洋云亮点（MCB）作为降低全球/区域温度的工具来研究太阳辐射管理（SRM）（SRM）的局限性来挑战这一假设。这是定量预测这两个最常讨论的SRM方案的局限性的首次全面尝试。这将首次在并联SAI和MCB的局限性上进行量化。我们推测，这些局限性可能会对法律和政治效应产生深远的影响，这些局限是将缓解和序列缓解，适应和气候工程措施（包括气候公平政治）的联系。涵盖详细的气溶胶和云微物理学的先进大气数值模型用于确定两种SRM技术的物理极限。然后，这些结果将构成SPP中的基础，以综合评估不同的法律CE政府制度以及二氧化碳缓解，适应和气候工程之间的相互作用。
