Social Costs of Methane and Carbon Dioxide in a Tipping Climate
在一个可解析的模型中推导了甲烷和二氧化碳排放的社会成本，考虑了气候临界点风险和确定性损害，发现甲烷的相对社会成本在核心模型中恒定，但其他假设下会随时间变化。
Abstract Social costs for methane and carbon dioxide emissions, from the risk of climate tipping events and deterministic damages, are derived in an analytically tractable model. In the core model: social costs from tipping risks rise with income, just as they do for deterministic damages, and depend on only a few parameters. Consequently, methane’s weight (its social cost relative to carbon dioxide) is constant and independent of temperature projections. But other damage and tipping probability formulations assumed in the literature imply methane’s weight varies over time and with temperature projections..
