从IPCC WGI前六次科学评估报告看第七次评估报告的进展OA

This paper reviews the development of the first six scientific assessment reports of the IPCC Working Group Ⅰ(WGⅠ),summarizing significant progress in areas such as author representation,observational data,climate models,attribution of human activities,and future projections.Building on this foundation,it looks ahead to potential innovations in the Seventh Assessment Report(AR7).The article notes that from the FAR(1990)to AR6(2021),the reports have continuously deepened in content,with improved model resolution,broader author representation,and substantially increased scientific certainty regarding the impact of human activities on climate change.It is anticipated that AR7 will achieve further breakthroughs in areas such as optimized scientific framework,methodological innovations,expansion of key topics,and enhanced collaboration across working groups,thereby providing more precise and systematic scientific support for global climate governance.
