回顾了2022年全球气候变化与治理领域取得的系列令人瞩目的成果。介绍了2022年全球温度持续升高、温室气体浓度创新高、海冰范围缩小及海平面上升等气候变化科学共识；“三重”拉尼娜重现、南亚高温洪水、欧洲及中国高温干旱等极端天气气候事件；全球碳减排承诺、多灾种预警系统、IPCC第六次评估报告（AR6）、第27届联合国气候变化大会（COP27）、生物多样性大会（COP15）等全球气候变化治理与认知方面的最新进展。
In 2022 human society suffered from multiple crises including climate change, the COVID-19 pandemic and RussiaUkraine war, etc. This paper reviews a series of impressive results in the field of global climate change and climate governance in 2022. Recent progress on climate change is introduced from the point of view of continuous rising global temperature, record breaking greenhouse gas concentration, shrinking sea ice extent and rising sea level. Triple La Niña re-emergence, catastrophic heat wave-heavy flood in South Asia and heat wave-severe drought in Europe and China are selected as cases of extreme weather and climate events. Updating of global carbon commitment, promotion of the Multi-hazard Early Warning System (MHEWS), publication of IPCC Sixth Assessment Report (AR6) WGⅡ and WGⅢ, holding of the 27th United Nations Climate Change Conference (COP27) and the Biodiversity Conference (COP15) are highlighted to show the actions on global climate governance and updated cognition of climate change.
