摘要
2021年8月,政府间气候变化专门委员会(IPCC)第六次评估报告第一工作组报告发布。该报告清楚表明,近百年来气候系统正在发生广泛而迅速的变化,人类活动已使得大气、海洋和陆地变暖。本文通过对报告第三章的摘译,介绍了报告中关于人类活动对气候系统影响的主要结论,包括人类活动对大气和地表、冰冻圈、海洋、生物圈以及气候变率的影响。基于最新的观测资料、新一代气候模式结果以及不同的检测归因方法,通过评估近年来该领域的最新文献表明,以温室气体为主的人类活动可以在气候系统多变量变化中被检测出来。
In August 2021,the Working GroupⅠ(WGI)report of the Sixth Assessment Report(AR6)of the Intergovernmental Panel on Climate Change(IPCC)was released.The report has concluded that human activities have warmed the atmosphere,ocean and land.Widespread and rapid changes in the atmosphere,ocean,cryosphere and biospherehave occurred.This paper presents the main conclusions of the report on the impact of human activities on the climate system,including the impact of human activities on the atmosphere and surface,the cryosphere,the ocean,the biosphere and the climate variability.It is clear that based on recent literatures in the filed of climate change detection and attribution,anthropogenic forcing signal,which is dominated by greenhouse gases,has been detected in multivariable changes in the climate system.The uses of the newest observational data,the latest generation of climate models and the updated attribution methods provide solid basis for these conclusions.
