The greenhouse effect was discovered first, who proposed it first, and when

1997 year.

Since 1997, China has held a symposium during the "Two Sessions" for seven consecutive years to listen to reports on environmental protection work and make arrangements for environmental protection work. China's state leaders believe that environmental protection is a major matter for strengthening the country, enriching the people, and ensuring the safety of the world, and has a bearing on the country's environmental security. The essence of protecting the environment is to protect productivity.

It is necessary to establish and improve a comprehensive decision-making mechanism for environment and development, and all localities must personally grasp and take overall responsibility for environmental problems. It is necessary to strengthen unified environmental supervision, increase environmental investment, and encourage public participation. We must insist on paying equal attention to pollution prevention and ecological protection.

It is necessary to highlight the key points and pay close attention to the prevention and control of pollution in key cities, river basins, regions, and sea areas. In the reform of state institutions, the environmental protection sector has been continuously strengthened.

The greenhouse effect is caused by an increase in the amount of greenhouse gases (carbon dioxide, methane, etc.) in the atmosphere.

The air contains carbon dioxide, and the levels have remained largely constant for a long time in the past. This is due to the fact that the carbon dioxide in the atmosphere is always in a state of dynamic equilibrium of "increasing and growing, and consuming at the same time". 80% of the carbon dioxide in the atmosphere comes from the respiration of people and plants, and 20% comes from the combustion of fuels.

75% of the carbon dioxide scattered in the atmosphere is absorbed and dissolved in water by water on the ground such as oceans, lakes, rivers, and air precipitation. Another 5 percent of carbon dioxide is converted into organic matter through plant photosynthesis and stored. That's why the volume fraction of carbon dioxide as a percentage of air components has remained the same for many years.

However, in recent decades, due to the rapid increase in population and the rapid development of industry, the carbon dioxide produced by breathing and the combustion of coal, oil, and natural gas has far exceeded the levels of the past. On the other hand, deforestation has led to the creation of cities and factories on large amounts of farmland, destroying vegetation and reducing the conditions for converting carbon dioxide into organic matter. In addition, the gradual shrinking of surface waters and the greatly reduced precipitation have reduced the conditions for absorbing dissolved carbon dioxide, and destroyed the dynamic balance between carbon dioxide production and transformation, so that the carbon dioxide content in the atmosphere has increased year by year.

The increase in the amount of carbon dioxide in the air is expected to change the temperature of the earth.

Carbon dioxide prevents surface heat from radiating into space and has the function of regulating the earth's air temperature. Without carbon dioxide, the Earth's average annual temperature would be 20 percent lower than it is today. However, if the carbon dioxide content is too high, the earth will feel like it is in a pot, and the temperature will gradually rise, forming a "greenhouse effect".

Gases that form the greenhouse effect, in addition to carbon dioxide, there are other gases. Among them, carbon dioxide accounts for about 75, chlorofluoroalkane accounts for about 15% 20, and there are more than 30 kinds of methane and nitric oxide.

The greenhouse effect is a phenomenon in which the global temperature rises due to an increase in the amount of carbon dioxide and other gases in the atmosphere. If carbon dioxide levels were to double what they are now, global temperatures would rise by 3.5 and the poles could rise by 10 and the climate would warm significantly. Rising temperatures will lead to increased rainfall in some areas, drought in some areas, increased intensity and frequency of hurricanes, and intensification of natural disasters.

More worryingly, many coastal cities, islands or low-lying areas will be threatened by seawater** or even swallowed by seawater due to rising temperatures, which will melt glaciers in the polar regions and raise sea levels. At the end of the sixties of the twentieth century, there was a drought in the pastoral areas of the lower Sahara of Africa that lasted for six years. Livestock were slaughtered due to a lack of food and pasture, and more than 1.5 million people died of starvation.

This is a classic example of the "greenhouse effect" that has brought disaster to mankind. Therefore, it is necessary to effectively control the increase in carbon dioxide content, control population growth, use fuel scientifically, strengthen afforestation, green the earth, and prevent the global catastrophe brought by the greenhouse effect.

The greenhouse effect is mainly caused by carbon dioxide.

The greenhouse effect, also known as the "flower house effect", is a common name for the atmospheric insulation effect. The atmosphere can make the solar short-wave radiation reach the ground, but a large number of long-wave thermal radiation released outward after the surface is heated are absorbed by the atmosphere, so that the surface and the low-level atmospheric atmosphere act like a greenhouse for cultivating crops, hence the name greenhouse effect.

Since the Industrial Revolution, the amount of heat-absorbing greenhouse gases such as carbon dioxide emitted into the atmosphere has increased year by year, and the greenhouse effect of the atmosphere has also increased, causing a series of problems that have attracted the attention of countries around the world.
