摘要:

2025年3月初,政府间气候变化专门委员会(IPCC)第62次全会审议通过并发布第七次评估周期第二工作组(WGII)报告大纲,为下一步编写第七次评估报告(AR7)提供了科学基础和行动指南。报告包括概要、全球评估、区域评估和领域评估四部分内容共20章,此外,还计划对《IPCC气候变化影响和适应评估技术指南(1994年)》进行更新并新增关于适应工具、模块和推动因素的内容,旨在通过系统性风险分析、包容性框架设计及方法论创新,更加全面科学地评估气候变化影响、适应与脆弱性及其最新研究进展,为全球气候政策和行动提供科学依据。文中简述了AR7 WGII关注的全球评估、区域评估和领域评估的内容和要点。与第六次评估报告(AR6)相比,AR7 WGII在整体架构上呈现了3个新特点:(1)将全球评估置于区域和领域专题评估之前,强化对跨尺度风险的整合分析;(2)突出适应措施的有效性评估;(3)新增应对损失损害和资金章节。基于AR7 WGII报告大纲,文中在全球和区域范围、水资源管理、农业发展、公共健康与生计保障等多个领域提出了研究关键点和重要启示,为未来气候变化影响、适应与脆弱性评估的研究提供了科学框架,对推动全球范围内的气候变化应对措施和实现可持续发展目标具有重要意义。

Abstract:

In early March 2025, the 62nd plenary session of the United Nations Intergovernmental Panel on Climate Change (IPCC) considered, adopted and released the outline of the report of Working Group II (WGII) of the Seventh Assessment Report (AR7), which provides a scientific basis and action guidelines for the next step in the preparation of the AR7. The outline clearly sets out the four major topics of summary, global assessment, regional assessment and thematic assessment in a total of 20 chapters. In addition, it is planned to update the IPCC Technical Guidelines for Assessing Impacts of and Adaptation to Climate Change (1994) and add new content on adaptation tools, modules and drivers. WGII aims to provide a more comprehensive scientific assessment of climate change impacts, adaptation and vulnerability, as well as the latest research progress through systematic risk analysis, inclusive framework design and methodological innovations, and it will provide a scientific basis for global climate policies and actions. This article briefly describes the contents and key points of the global assessment, regional assessment and thematic assessment areas of concern in AR7 WGII. Compared with the Sixth Assessment Report (AR6), the AR7 WGII presents three new features in its overall structure: (1) The global assessment will be placed before the thematic (sectoral and domain) assessments, and the integrated analysis of cross-scale risks will be strengthened; (2) The assessment of the effectiveness of adaptation measures will be emphasized; (3) New chapters will be added on response to loss and damage, as well as finance. Based on the outline of the WGII report, key research points and important insights are proposed in various areas such as global and regional scales, water resources, agricultural development, public health and livelihoods security, etc., which provide a scientific framework for future research on climate change impacts, adaptation and vulnerability, and are of great significance in promoting climate change response measures and realizing the sustainable development goals on a global scale.

Key words: IPCC, Seventh Assessment Report (AR7), Working Group II (WGII), Report outline, Climate change, Impacts, adaptation and vulnerability
