Steering the Climate System: Using Inertia to Lower the Cost of Policy: Reply
回应Mattauch等人对Lemoine和Rudik（2017）气候模型稳健性的质疑，指出原模型扩展后仍支持其结论，并量化了惯性对减排成本和初始碳税的影响。
Mattauch et al. (2020) claims that the quantitative conclusions in Lemoine and Rudik (2017)—henceforth, LR17—are not robust to using a climate model consistent with recent scientific results. We observe that LR17 in fact analyzes an extension to a more realistic carbon model that generates an efficient emission tax trajectory very similar to that in Mattauch et al. (2020), and we here show that simplifications in the temperature model of LR17 do not qualitatively affect their policy conclusions. Accounting for inertia reduces the initial emission tax by 42 percent and reduces the present value of abatement cost by 39 percent.
