Here, the authors improve climate-induced economic impact assessment, without considering social and ecological damages, for 12 scenarios by assimilating projections from 48 climate models into the PAGE-ICE model. The sustainable development pathway, including considerable implicit carbon dioxide removal, cost-effectively mitigates climate change impacts, as can scenarios that combine politically pledged emissions reductions with moderate solar geoengineering (SAI-1.5). Additionally, they find that combining solar geoengineering with no mitigation (G6) or implementing delayed but stringent carbon dioxide removal (SSP5-3.4-OS) can respectively reduce end-of-century climate damages to one-half or a one-quarter of the baseline SSP5-8.5 scenario.
