The cause of the global warming is the exacerbation of the global warming effect

Mainly A, auxiliary B

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.

Modern industry burns a lot of coal and oil to produce a large amount of carbon dioxide, and a large number of deforestation and construction have caused a sharp decline in the earth's vegetation and reduced the absorption of carbon dioxide by living organisms.

Freon destroys the ozone layer, causing ultraviolet rays to shine directly on the earth's surface, causing organisms to mutate and die. But not to exacerbate the global warming effect.

Photosynthesis in plants is the production of oxygen, not carbon dioxide.

c Because it only exacerbates.

Life on Earth was able to survive mainly because sunlight warmed the planet as it entered the atmosphere. At the same time, some sunlight is reflected back into space so that the Earth doesn't get too hot, creating a delicate balance. However, with the development of human industrial activities (burning fossil fuels, deforestation, etc.), more and more greenhouse gases are being released into the atmosphere.

Greenhouse gases have a blocking effect on the reflection of heat, which leads to a rise in global temperatures.

Climate scientist Norman Le says the planet is heating up at an unprecedented rate, much faster than expected, equivalent to adding 20 electric teapots to all the people on the planet. The effects of global warming are becoming more and more apparent. Climate warming exacerbates the instability of the climate system and is an important background for the frequent occurrence of extreme weather and climate events.

Statistics show that the frequency of extreme heat events in the Northern Hemisphere has increased in recent decades. Since the beginning of the 21st century, heat wave events in the United States have become more frequent, and the total number of high temperature days from 2001 to 2020 has increased by about 50% compared with 1981 to 2000.

The study also showed that as the climate warms, the atmosphere can hold more water vapor before it becomes saturated, making extremely heavy precipitation more likely. Global warming will also cause a redistribution of global precipitation, melting glaciers and permafrost, rising sea levels, etc., which will seriously damage the earth's ecosystem. Rising temperatures may bring kinetic energy to the air and oceans, forming natural disasters such as mega typhoons and tsunamis, which will occur more and more frequently, destroying human buildings and endangering health and safety, and also bringing landslides to block roads and damage buildings, bringing great safety risks to human beings.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

As a result, global warming will lead to a lack of water in the land, a decrease in food production, a shortage of freshwater resources, a global drought, and an increase in greenhouse gas levels.

In this way, the image of the global picture has warmed, the land is deprived of water, food production has increased, the cost of drinking water is poor, the global drought disaster has occurred, and the greenhouse gas content has increased.

It can lead to drought on the continent, it will also lead to a decrease in food production, it will cause the temperature of the land to become higher, there will be a lack of water, it will also lead to a shortage of fresh water resources, the melting of icebergs, and it will cause a lot of extreme climates on the earth.

Global warming intensifies, the global climate will also change, severe weather or natural disasters will occur in many parts of the world, glaciers in the Arctic and Antarctic will continue to melt, and the sea level will rise.

It is easy to cause disasters, it is easy to cause heavy rains, it can lead to floods, it can lead to coastlines**, it can lead to natural disasters.

The ecological environment has been destroyed, and the amount of human activities is large. The ecological environment has been destroyed, causing the climate to become worse and worse; The large amount of human activity and excessive carbon emissions will also lead to climate warming.

The reason for climate warming is that the earth has been damaged, the atmosphere has been damaged, the carbon dioxide exhaled by human beings has increased, and the earth's environmental pollution is more serious.

I think the main cause of global warming is that people are constantly destroying the environment, so I think this behavior is very bad.

Gases that cause the greenhouse effect, such as C02, methane, various hydrochlorofluorocarbons, ozone, and water vapor, are called greenhouse gases. The greenhouse effect, also known as the "flower house effect", is a common name for the atmospheric insulation effect. The atmosphere can cause the sun's short-wave radiation to reach the ground, but a large amount of long-wave thermal radiation emitted by the surface is absorbed by the atmosphere.

In this way, the surface and the low-level atmospheric atmosphere act like a greenhouse for cultivating crops, hence the name greenhouse effect.

Atmospheric environmental pollution factors: Global climate change research clearly states that the temperature of the Earth's surface has been rising since the end of the last century; Deterioration of the marine environment: sea level change is on the rise, and experts may increase by 50 cm by the middle of the next century; Drastic reduction in forest resources:

The area of forests around the world is decreasing dramatically due to natural or anthropogenic factors.

<> the greenhouse effect, which is a common topic, carbon dioxide emissions such as industrial production and automobile exhaust gather at a certain height and put on a "cotton suit" to cause the average temperature of the world to rise. In this case, the increase in ocean evaporation, fluctuations in atmospheric circulation, and the constant movement and change of high ridge lines and low-pressure streams have led to intensive rainfall in individual areas, as was the case in our Yangtze River basin back then. Scientists attribute the global warming trend observed since the middle of the 20th century to the expansion of the human "greenhouse effect".

The "greenhouse effect" is when the atmosphere moves the Earth's heat away from radiation into space, causing the world to become more moderate. Some gases in the atmosphere prevent the spread of heat. Semi-permanent gases in the atmosphere, which have no physical or chemical reaction to temperature changes, are described as "violent" climate change.

gases, such as water vapor.

Scientists believe that since the middle of the 20th century, the trend of global warming has been the "greenhouse effect" of human expansion, which leads to a warming climate when the atmosphere absorbs heat from Earth to space. Some gases in the atmosphere prevent heat loss. In the atmosphere, long-lived gases remain semi-permanent and do not respond to physical or chemical temperature changes, known as "forced" climate change.

Gases, such as water vapor, are physically or chemically responsive to temperature changes. Pessimistic arguments about inaction and complacency are wrong, because they do not correspond to the historical facts of the development of human society nearly a million years ago, as well as the facts of natural history that we know so far, such as the history of celestial bodies, the history of the earth, biology and other natural sciences. ”

Carbon dioxide, car exhaust, gases from coal burned to heat people in winter, pollutants, gases from household garbage.

Water vapor, ozone, methane, C02, various hydrochlorofluorocarbons, and environmental pollution in the atmosphere are the main causes of the greenhouse effect.

The most important gas responsible for the greenhouse effect is carbon dioxide. This gas is mostly polluted in automobile exhaust industrial pollution. industrial exhaust gases.

Gases are the main cause of global warming.
