The Change of Climate and Ecological Environment in China 2021: Synthesis Report

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 outand 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.

Dahe Qin, geographer, and academician of the Chinese Academy of Sciences and the Third World Academy of Sciences. He is currently the director of the Academic Committee of the Chinese Academy of Sciences and chairman of the Executive Committee of the Asian Geographic Society.

Academician Dahe Qin has long been engaged in the reasearch of cryosphere, climate change and sustainable development. His studies of cryospheric changes and their effects and adaptation and of the functioning cryospheric services contribute to build the theoretical framework of the cryospheric science. Being the founder of the State Key Laboratory on Cryospheric Science and of the Society on Cryospheric Science in China, he has led the compilation of textbooks on cryosphere. All this has contributed to the development of the cryospheric science. He was involved in the leadership of the preparation of the Third, Fourth and Fifth Assessment Reports of the Intergovernmental Panel on Climate Change (IPCC), and also the assessment of climate and environment in China, and of extreme weather and climate events and disaster risk management in China, making significant contributions to deepening the understanding of climate change science. He was awarded the 2008 International Meteorological Organization Prize, the 2013 Volvo Environment Prize, the Second Prize of (China) National Natural Science Award, Grand Prize of 2021 National Excellent Textbook (Higher Education), and 2022 International Geographical Union Lauréat d'Honneur. He has published more than 400 papers and 30 books.
