What are the main causes of the greenhouse effect and its impact on human life?

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.

Effects of the greenhouse effect.

1) an increase in pests, diseases and infectious diseases on the planet;

2) sea level rise;

3) abnormal weather and an increase in ocean storms;

4) The land is arid and the area of desertification is increasing.

Ha, I also saw this question when I was doing small exercises. Find out online. That's it)

Cause: The greenhouse effect is mainly caused by the excessive burning of coal, oil and natural gas in modern industrial societies, which release large amounts of carbon dioxide gas into the atmosphere after combustion.

Impact: The effects of the greenhouse effect.

1) an increase in pests, diseases and infectious diseases on the planet;

2) sea level rise;

3) abnormal weather and an increase in ocean storms;

4) The land is arid and the area of desertification is increasing.

Species are extinct, plants are dying, sea levels are rising, and humans will not be able to survive.

The greenhouse effect is a big political **, hackers stole some so-called scientific information, and found that a lot of data was falsified and manipulated. Carbon dioxide accounts for less than 5% of greenhouse gases, and human activities produce less than 5% of carbon dioxide. The reason for the hype is to cheat money.

In fact, human activity has very little effect on temperature, as can be seen in the BBC documentary.

The 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 to the earth cannot be dispersed to outer space, reflecting ultraviolet rays, and the result is that the surface of the earth becomes hot. 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 more concerned that under the greenhouse effect of increasing global temperatures, the probability of male babies being born will be higher and higher, which may cause an imbalance in the ratio of men to women.

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 carbon dioxide in the atmosphere is always in a state of dynamic equilibrium of "growth and consumption". 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 has changed the temperature of the earth.

Carbon dioxide can prevent the 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 todayHowever, if the carbon dioxide content is too high, the earth will seem to be 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, due to the melting of glaciers in the polar regions due to rising temperatures, the sea trace level will rise, and many coastal cities, islands or low-lying areas will be threatened by seawater** or even swallowed by seawater. At the end of the 60s of the 20th century, the pastoral areas of the lower Sahara in Africa experienced a drought 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.

Carbon dioxide is the substance that causes the greenhouse energy effect.

Methane, ozone, nitrous oxide.

Freon and water vapor, etc.

The greenhouse effect refers to the lack of thermal convection between a confined space that transmits sunlight and the outside world.

The thermal insulation effect is that the solar short-wave radiation can penetrate the atmosphere into the ground, but the long-wave radiation released after the ground warms is absorbed by the carbon dioxide and other substances in the atmosphere, resulting in the effect of atmospheric warming.

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 large-buried landslide gas, which increases the temperature of the surface and the lower atmosphere, because its effect is similar to the greenhouse for cultivating crops, so it is called the greenhouse effect.
