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
