英文摘要:
Until recently, analysis of optimal global climate policy has focused on mitigation. Exploration of policies to meet the 1.5{\\deg}C target have brought carbon dioxide removal (CDR), a second instrument, into the climate policy mainstream. Far less agreement exists regarding the role of solar geoengineering (SG), a third instrument to limit global climate risk. Integrated assessment modelling (IAM) studies offer little guidance on trade-offs between these three instruments because they have dealt with CDR and SG in isolation. Here, I extend the Dynamic Integrated model of Climate and Economy (DICE) to include both CDR and SG to explore the temporal ordering of the three instruments. Contrary to implicit assumptions that SG would be employed only after mitigation and CDR are exhausted, I find that SG is introduced parallel to mitigation temporary reducing climate risks during the era of peak CO2 concentrations. CDR reduces concentrations after mitigation is exhausted, enabling SG phasing out.

中文摘要:
直到最近,对最佳全球气候政策的分析一直侧重于缓解气候变化。探索实现1.5摄氏度目标的政策,将第二个工具二氧化碳去除(CDR)纳入气候政策主流。关于限制全球气候风险的第三个工具——太阳能地球工程(SG)的作用,目前还没有达成一致意见。综合评估建模(IAM)研究对这三种工具之间的权衡提供的指导很少,因为它们单独处理CDR和SG。在此,我扩展了气候与经济动态综合模型(DICE),将CDR和SG都包括在内,以探索这三种工具的时间顺序。与仅在缓解措施和CDR耗尽后才使用SG的隐含假设相反,我发现SG的引入与缓解措施平行,即在CO2浓度峰值期间临时减少气候风险。CDR在缓解措施耗尽后降低浓度,从而使SG逐步淘汰。
