摘要/Abstract

摘要：

文中对IPCC第六次评估报告第二工作组报告关于观测和预估的气候变化影响与风险方面的主要结论进行了解读。报告表明,气候变化已经对自然和人类系统造成了广泛的不利影响,尤其是气候变化下的复合风险和极端事件呈现日益加剧和频繁的趋势。目前,不同地区和部门的关键风险已多达127种,且随着气候变暖以及生态社会脆弱性的加剧,将对人类和生态系统造成更加普遍和不可逆的影响。相对第五次评估报告,本报告进一步扩展了风险的内涵,归纳了8个代表性关键风险,更加全面地评估了5个“关注理由”的风险水平,评估结果有利于加深对于气候变化影响的认识和及时制定行动对策。

Abstract:

This paper interprets the main conclusions of the Working Group II report of the IPCC Sixth Assessment Report on observed and projected impacts and risks of climate change. The report shows that climate change is already causing widespread adverse effects on natural and human systems, with compounding risks and extreme events increasing in intensity and frequency under climate change. At present, there are more than 127 kinds of key risks in different regions and sectors, which will have more widespread and irreversible impacts on people and ecosystems as climate warming and ecological social fragility intensify. Compared with the Fifth Assessment Report, the Sixth Report further expands the framework of risks, summarizes 8 representative key risks, and evaluates the risk level of 5 “reasons for concern” in a more comprehensive way. The assessment results are conducive to deepening the understanding of the impact of climate change and formulating timely action countermeasures.

Key words: IPCC Sixth Assessment Report (IPCC AR6), Working Group II (WGII), Climate change, Impact, Risk
