This book analyzes China's climate and environmental change facts, impacts and vulnerabilities, and mitigation strategies. On basis of synthesis assessment, through comprehensive integration, it focuses on four aspects: climate change and ecological environment evolution, future climate change and risk prediction, technical measures and action results for adaptation and mitigation, and development path with climate resilience. In terms of change facts, it focuses on extreme climate events, large-scale factors affecting China's climate change, and the impact of climate change on China's social and economic system. In terms of future risks, it focuses on key variables such as temperature, precipitation and other key variables and the prediction of future changes in extreme climate events. Potential risks in resources, agriculture, cryosphere, ecology, human settlements, health and major projects are also discussed. In terms of adaptation and mitigation, this book systematically sorts out and summarizes the effects, policy choices and synergies of climate change adaptation and mitigation from two perspectives, global and Chinese. Finally, from the perspectives of carbon emission path, sustainable development, and building a community with a shared future for mankind, it explains the essentials of choosing a development path with climate resilience.
