Anonymous users2024-02-06The greenhouse effect refers to the thermal insulation effect formed by the lack of heat exchange between the confined space that transmits sunlight and the outside world, that is, the solar short-wave radiation can penetrate the atmosphere into the ground, and the long-wave radiation released after the ground warms is absorbed by the carbon dioxide and other substances in the atmosphere, thus producing the effect of atmospheric warming.
Reason: The greenhouse effect is mainly caused by the excessive burning of coal, oil and natural gas in modern industrial society, and the large amount of exhaust gas emitted, and the combustion of these fuels releases a large amount of carbon dioxide gas into the atmosphere. Carbon dioxide gas has the function of heat absorption and heat insulation.
As a result of its increase in the atmosphere, it forms an invisible glass cover, so that the heat radiated by the sun to the earth cannot be dispersed into outer space, reflecting ultraviolet rays, and as a result, the surface of the earth heats up. As a result, carbon dioxide is also known as a greenhouse gas.
Impact: Impact on the environment:
Global warming. Pests and diseases on the planet are on the rise.
Sea level rises.
The climate is abnormal. Desertification of the land.
Impact on the economy:
More than half of the world's population lives within 100 kilometres of the coast, with the majority living in urban areas near seaports. As a result, significant sea level rise will cause serious economic damage to low-lying coastal areas and islands, such as accelerating the erosion of coastal beaches and pushing fresh groundwater further inland by rising seawater.
Impact on Agriculture:
Experiments have shown that plants grow faster and taller in environments with high concentrations of CO2. However, the results of 'global warming' can affect atmospheric circulation, which in turn alters the global rainfall distribution and the moisture content of surface soils on all continents. The impact of global warming on regional climates is not well understood, and the changes to plant ecology are uncertain.
Impacts on marine ecology:
The disappearance of coastal marshy areas will certainly lead to a decline in the number of fish, especially shellfish. Saltier estuarine water quality may reduce the number of freshwater fish species, and conversely, the number of marine fish species in the area may also increase. The impact on the overall marine ecology is still not well understood.
Effects on the water cycle:
Rainfall is likely to increase globally. However, changes in regional rainfall are still unknown. Some areas may receive more rainfall, but others may receive less rainfall. In addition, higher temperatures increase water evaporation, which puts pressure on the use of water sources on the ground.
Effect on the balance of male and female ratios:
It is easy to create a baby boy in a high temperature environment, and it is easy to create a baby girl in a low temperature environment. Researchers are concerned that the global warming effect will increase the probability of male babies being born, which may lead to an imbalance in the ratio of male to female babies.
First, the reasons are different
1. Greenhouse effect. >>>More
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. >>>More

The rise in global temperatures by about 2 degrees Celsius has been accomplished in the last 200 years, a process that is the result of industrialization and the destruction of forests. >>>More
The main reason: the increase in the concentration of carbon dioxide in the atmosphere, which prevents the heat of the earth from being dissipated, and promotes the warming of the earth's temperature. >>>More
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. >>>More
