With human progress and rapid economic development, especially the acceleration of industrialization, carbon dioxide emissions have reached the highest value and the fastest growth rate in history, and the global climate is undergoing a significant change characterized by global warming. A series of scientific studies have confirmed that greenhouse gas emissions such as carbon dioxide are the main cause of global warming. The Antarctic Law Dome ice core data show that since the industrialization of humans in 1750, the concentration of carbon dioxide in the atmosphere has increased significantly, from 280 ppmv to more than 370 ppmv; the latest global annual average temperature data provided by the National Ocean University Administration of the United States shows that Six of the seven warmest years in the past hundred years occurred after 2001, of which 2006 was the sixth hottest year since the instrumental meteorological record was available in 1861; issued by six departments including the Ministry of Science and Technology of China, the China Meteorological Administration, and the Chinese Academy of Sciences The “National Assessment Report on Climate Change” stated that the speed of climate change in China will further accelerate in the future, and the national average temperature is likely to rise by 2°C to 3°C in the next 50-80 years.
Climate warming will bring about many effects: First, it will cause the sea level to rise. Scientists predict that if the temperature of the earth’s surface rises at the current rate, the global temperature will rise by 2°C~4°C by 2050, the glaciers in the Antarctic and Arctic will melt substantially, and the sea level will rise by 0.09~ from 1990 to 2100. 0.88 meters, some island countries and coastal cities will be submerged. Second, it will cause a decrease in crop yields in some areas. Due to climate warming, rainfall is drastically reduced, which will have a negative impact on crop yields, which will increase global food prices and may increase the risk of hunger for vulnerable populations. Third, it will exacerbate water shortages in many water-deficient areas in the world. The warming of the climate reduces the quality of fresh water due to the increase in water temperature, greatly reducing the water supply in many water-scarce areas in the world, and causing a worldwide water shortage. In addition, global warming will also increase the number of pests and diseases on the earth and frequent extreme climates. In recent years, many countries in the world have been affected by severe storms, floods and droughts, causing a lot of loss of life and property around the world, and bringing huge harm to human production and life.
