      摘要: 介紹了政府間氣候變化專門委員會(IPCC)為第五次評估報告開發(fā)的新情景——代表性濃度路徑(RCPs),分析了RCPs情景的內(nèi)在優(yōu)勢,并描述了4類代表性RCPs(RCP8.5、RCP6、RCP4.5和RCP3-PD)的特征。利用IPCC最新發(fā)布的RCPs數(shù)據(jù),分析了高端、中端穩(wěn)定和低端濃度路徑下,全球溫室氣體的排放空間、區(qū)域分擔(dān)和減排成本,并著重探討了低端路徑與全球溫度升幅限制在2℃以下目標(biāo)之間的關(guān)系及其給中國帶來的主要挑戰(zhàn)和應(yīng)對途徑。

      Abstract: This paper overviews the new set of integrated scenarios, representative concentration pathways (RCPs), provided by the Intergovernmental Panel on Climate Change (IPCC) for the fifth assessment process, analyzes the advantages of new approaches to scenarios development, and depicts the characteristics of the identified four RCPs (RCP8.5, RCP6, RCP4.5 and RCP3-PD). By using the RCPs database updated by IPCC, the paper analyzes the global greenhouse gas (GHG) emissions, regional emissions and emission abatement costs under the high, intermediate-range and low RCP scenarios. More importantly, the paper investigates the relationship between low RCP and keeping the global temperature rise below 2℃, identifies the challenges brought to China, and presents China’s countermeasures for addressing the challenges.
