Abstract

IPCCの第5次評価報告書の第1作業部会報告書が公表された.これまでのSRES (Special Report on Emission Scenarios)シナリオに代わって,RCP (Representative Concentration Pathways)という代表的濃度経路シナリオに沿って結果が取りまとめられている.温暖化の主要な要因は人間活動であることを強調する点はこれまでと変わりないが,二酸化炭素の累積排出量と平均気温の上昇量はほぼ比例関係にあるという新見解,ジオエンジニアリングと呼ばれる気候変動に対抗する方法についても述べられている.ここでは,こうした気候変動の影響が大きいと考えられている日本の豪雪地帯における水資源変動予測に関する研究事例,また,海面上昇,洪水などの影響に対して脆弱なベトナム・メコンデルタにおける研究事例について紹介した.

The contribution of Working Group I to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (AR5) is discussed in this study. Representative Concentration Pathways (RCP) scenarios are used rather than Special Report on Emission Scenarios (SRES) in the AR5. In this report, it is stated that human influence likely has been the dominant factor in observed global warming since the mid-20th century. Although this evidence is the same as that previously reported, new opinions are also offered. For example, cumulative CO_2 emissions are expected to largely determine global mean surface warming by the late 21st century, and geoengineering methods that aim to deliberately alter the climate system may counter climate change. In this study, we introduce a water resource change projection study in a heavy-snow region where the climate change impacts are significant, and an impact evaluation study in the Mekong Delta, which is highly susceptible to rising sea levels and flooding.
