后疫情时代，全球气候变化影响和应对呈现新趋势，突发性、全球性和关联性成为鲜明的特征。当前，要着力解决应对气候变化的重大科学问题，就必须继续务实加强基础研究，妥善处理应对全球变化的挑战和可持续发展之间的关系；根据中国国情选择自己的气候变化应对之路；进一步处理好减排与增汇、减缓与适应的关系；设立国家碳中和重大专项；制定和实施更大规模植树造林计划；要立足未来，密切关注与气候变化高度关联的人类长期发展议程，实现人类可持续发展。

Global climate change is a common hot issue facing the world. For a long time, mankind believed that nature had a great decisive influence on human society, and never thought that human activities could have an impact on nature, or even a profound impact. With the accumulation of scientific knowledge and the deepening of understanding of the natural world, mankind’s concept of nature has begun to change, believing that they can transform nature, and even dominate nature. Especially after the Industrial Revolution, this process has been accelerated, causing serious damage and destruction to nature. Until all kinds of new and old natural disasters became more frequent and intense, and the spread of plagues and infectious diseases became wider, some people began to reflect on and re-examine human behavior. What kind of human behavior did harm to the earth? How did the earth react to human behavior? After the global pandemic is raging, what are the characteristics of the post-epidemic era?In the post-epidemic era, global climate change impacts and responses are showing new trends, with suddenness, globality, and relevance becoming distinctive features. At present, to focus on solving the major scientific issues of climate change, we must continue to strengthen basic research pragmatically, properly handle the relationship between the challenges of global change and sustainable development; choose our own path to respond to climate change according to my country’s national conditions; further Deal with the relationship between emission reduction and increase in sinks, mitigation and adaptation; establish a major national carbon neutral project; formulate and implement larger-scale afforestation plans; focus on the future and pay close attention to the long-term human development agenda that is highly related to climate change to achieve Sustainable human development.
