Fig. 5: Marginal and mitigation costs in stochastic scenarios with a global temperature increase limit of 1.5 °C for the year 2100 and uncertainty and learning on CS.
From: Prudent carbon dioxide removal strategies hedge against high climate sensitivity
a Marginal costs in 2050 for all nine stochastic (box plot denoting the full range, quartiles, and median) and deterministic CS scenarios (red line), color-coded to show over/underestimations scenarios and correct bet scenarios. b Cumulative, discounted mitigation costs in 2020–2100 under an average CDR realization and the three CDR assumptions c Cumulative mitigation costs relative to GDP under an average CDR realization and the three CDR assumptions divided into near-term (2020–2050) and long-term (2050–2100) costs. The lines in (b) and (c) represent means over the 64 stochastic pathways and the shading shows the total range of the pathways.
