We should develop all aspects and the whole process, and accelerate the construction of a green and low-carbon development model with Chinese characteristics. Scientific research and observational data show that the global climate is undergoing changes with warming as the main feature in the past century. Since the Industrial Revolution, human activities, especially in the industrialization process of developed countries, emit a large amount of greenhouse gases, which are the main factors of current global climate change. Climate change has led to accelerated melting of glaciers and snow cover, unbalanced distribution of water resources, threats to biodiversity, and frequent occurrence of catastrophic climate events. Climate change also causes sea level rise, and coastal areas are more seriously affected by natural disasters such as floods and storm surges. Climate change adversely affects economic and social activities such as agriculture, forestry, animal husbandry, and fishing, aggravates the spread of diseases, and threatens economic and social development and population health. The adverse effects of global climate change will further increase in the future. my country is a country vulnerable to the adverse effects of climate change. In the past century, the fluctuation of regional precipitation in my country has increased, the precipitation in Northwest China has increased, the precipitation in Northeast China and North China has decreased, and coastal disasters such as coastal erosion and salt tide intrusion have increased. Global climate change has had an important impact on my country&#39;s economic and social development and people&#39;s lives. Since the 1950s, the area of glaciers in my country has shrunk by more than 10%, and has been shrinking rapidly since the 1990s. The frequency of extreme weather and climate events has increased, and the shortage of water resources in the north and the seasonal dryness in the south can be found realistically. In response to extreme policy actions, the National Leading Group on Climate Change and related working organizations have been established.
