论文摘要
累积排放核算二氧化碳（CO2）的基础是基于认识到地球系统模型中的全球变暖（ESMS）与累积CO2排放大致成正比，而不论排放途径如何。但是，累积排放会计仅要求全局变暖和累积排放之间的图近似独立于排放途径（“路径独立”），而不管这些变量之间的功能关系如何。对于能量平衡气候模型（EBM），考虑了路径独立性的概念和数学，从而引起了全球变暖的封闭式表达，以及对排放后大气周期的分析。路径独立性取决于排放周期和大气寿命之间的比率，如果排放周期的周期与大气寿命相当或短，则是有效的近似值。这使得累积排放量可能会在二氧化碳之外与其他温室气体（GHG）相关，并具有数十年的生命，其排放量最近已经开始。
Cumulative emissions accounting for carbon-dioxide (CO2) is founded on recognition that global warming in Earth System Models (ESMs) is roughly proportional to cumulative CO2 emissions, regardless of emissions pathway. However, cumulative emissions accounting only requires the graph between global warming and cumulative emissions to be approximately independent of emissions pathway ("path-independence"), regardless of functional relationship between these variables. The concept and mathematics of path-independence are considered for an energy-balance climate model (EBM), giving rise to a closed-form expression of global warming, together with analysis of the atmospheric cycle following emissions. Path-independence depends on the ratio between the period of the emissions cycle and the atmospheric lifetime, being a valid approximation if the emissions cycle has period comparable to or shorter than the atmospheric lifetime. This makes cumulative emissions accounting potentially relevant beyond CO2, to other greenhouse gases (GHGs) with lifetimes of several decades whose emissions have recently begun.
