What are the natural causes of global warming?

What are the natural causes of global warming? The climate of the earth is constantly changing. The last Little Ice Age was in the Ming and Qing Dynasties, and it has been warm ever since.

What do people think is the man-made cause of global warming? Human factors and human influence mainly include two aspects. On the one hand, people release a lot of greenhouse gases by burning fossil fuels in their daily production and life. In recent years, the emission of major greenhouse gases has been increasing, leading to the enhancement of greenhouse effect and global warming; On the other hand, changes in land use patterns, such as deforestation and the reduction of cultivated land, are indirect changes.

The natural causes of global warming are: the abnormal activity of the sun.

What are the causes of global warming? In the past, people always blamed the global temperature rise in this century on the greenhouse effect brought by human civilization, but now more and more scientists believe that the change of the sun itself may be another factor leading to the climate change of the earth. Some scientists believe that the change of the sun is the real cause of global warming. Now, experts are exploring three aspects that the sun may cause changes in the earth: the full brightness of the sun is considered to be a factor affecting the temperature change of the earth; The ultraviolet rays of the sun are considered to be the factors affecting wind power and atmospheric ozone content; Solar magnetic storms and subatomic particle storms are considered to be the factors that affect the precipitation and cloud cover of the earth. An important fact that attracts the attention of all scientists who study climate change is that from 1880 to now, the global average temperature seems to be rising gradually, increasing by nearly 1 Fahrenheit. What is the reason? Many scientists say that they can't know exactly how much climate warming is caused by nature and how much is caused by human activities. It is generally believed that gases that can release heat, such as carbon dioxide, are important reasons for the temperature rise. But carbon dioxide is not only a natural part of the atmosphere, but also released by cars, factories and the burning of oil, coal and wood all over the world. Carbon dioxide and other greenhouse gases are increasing, which prevent sunlight from reflecting back into space and make the earth warm.

What is the root cause of global warming? The answers upstairs are basically nonsense. If the landlord wants to know the relatively correct answer, you can listen to my opinion. Of course, all of us are not scientists, and the answer is not necessarily the right answer, but we all have our own answers to right and wrong!

If you are not tired of reading it, I can give you a thorough analysis of the climate problem.

First of all, let me make it clear that there is no problem with the climate. Basically this is the real situation!

According to historical data, from the end of World War II to 1975, the global climate gradually became cold, and then from 1975 to 2000, the climate became warmer. From 2000 to 20 10, the climate was not driven by continuous warming. Some experts believe that the climate has begun to get colder.

Let's analyze the above data. You can find that after the end of World War II, the industry developed at a high speed, emitting a lot of carbon dioxide, but the climate did not get warmer. On the contrary, from 75 years later to 2000, the temperature rose, and then until now, the temperature has not changed. It can be seen that the climate has a curve up and down process, which is about 25 years. This has nothing to do with carbon dioxide. Because if the increase of carbon dioxide will lead to an increase in temperature, there will be no process of temperature cooling after the end of World War II.

Then let's talk about carbon dioxide. Theoretically, carbon dioxide is indeed a kind of "insulation gas", but what I want to say is that the carbon dioxide emitted by human beings is actually very insignificant. The content of carbon dioxide in the atmosphere is 0.054%. The annual carbon dioxide produced by bacteria and fallen leaves is about 654.38+050 billion tons. Human-related activities, including breathing and automobile exhaust, are produced every year.

Moreover, from the study of the surface of ice samples, there are many ice ages and high temperature periods on the earth, but this is obviously different from the level of carbon dioxide content. Historically, the temperature always reached its peak several centuries after it reached its peak, but after it reached its peak, it gradually became cold.

The researchers concluded that during the high temperature period, due to the gradual increase of temperature, a large amount of carbon dioxide in the ocean was released, resulting in a high carbon dioxide content. When the temperature gradually decreases, the release of carbon dioxide will gradually stop until it is not released, and finally carbon dioxide will be "recycled", so the temperature will be different from the carbon dioxide content.

From this conclusion, we can find that our previous understanding that carbon dioxide causes high temperature has no scientific basis. The final answer is that temperature affects the content of carbon dioxide.

In addition, when it comes to heat preservation gas, the heat preservation effect of carbon dioxide is actually poor. Who is worse than it? Worse than water vapor, much worse ~ ~

Based on the above statement, we can draw the final conclusion that the process of climate warming is actually a normal change of the earth's climate. There was a warmer period on earth than now in history, that is, the Middle Ages, when the world society was quite rich, and most famous churches in Europe were built at that time, while in China, it was experiencing the peak of feudal society-Kaiyuan Shi Sheng! In addition, the industrial revolution was a famous ice age in history. At that time, the Thames was frozen, and vendors often set up shop on the ice in winter. So there is no problem with the climate, and the temperature changes are as normal as all the year round.

Then you may think, why is the slogan of "low carbon" so loud now when there is no problem with the climate?

I tell you, the Copenhagen conference, said to be a conference to save the planet, was actually a political conspiracy by economically developed countries to restrict the development of developing countries, and the environment was just used.

The global climate problem originated in Britain, and the initiator was Margaret Thatcher, the first famous female prime minister in Britain. Because of the acid rain phenomenon in Britain during her campaign, she put forward the campaign slogan of global environmental degradation and protection, which just catered to the psychology of two people. First, after World War II, because of the existence of the atomic bomb, human beings blindly realized that they had great power and thought that they could destroy the earth. The second is the fear of "having great power", which in turn will be destroyed by your own strength. So Thatcher took advantage of this slogan and became the first female prime minister in Britain. This law will be widely used by politicians in various countries in various political and economic fields, especially in the economic field.

The world economy is like a plate of water, and all countries in the world are like a plate of water. If you lay the plate flat, the water content in all parts of the plate is the same. If you hold it unevenly, some parts of the plate will get more water and some parts will get less water. However, the big countries led by the United States hope that the plate can tilt and get more water.

As a result, big countries throw out the just banner of "energy saving, emission reduction, low carbon and environmental protection", shouting this slogan loudly and confidently, taking environmental protection as the commanding height of morality, and making them "take the environment as the emperor and make them disobey me". Anyone who doesn't listen to him can punish you with this, and it can be cruel. Just as Christians punished pagans in the Middle Ages, they can use the stake. You have to understand that reducing carbon dioxide emissions means that for developing countries, output will drop and economic development will slow down. If you slow down, the advantages of developed countries such as the United States will become more obvious. The "water" of the economy will fall on the United States, and the "water" of the United States will naturally increase.

As the biggest victorious country in World War II, the United States successfully carved up the economy after World War II. Its content is that Africa, Asia and South America export raw materials and cheap crude products, and the first and second world countries (North America and Western Europe) led by the United States are responsible for logistics, advertising marketing, design, packaging and retail. The final product is digested by China or re-exported to developing countries. Among them, the profit of rough processing of raw materials export is the lowest, and the profit of logistics, advertising marketing, design, packaging and retail is the most abundant, so the western powers are rich and we are poor. This was carefully planned by the western developed countries headed by the United States.

However, developing countries are not necessarily satisfied with the status quo, and they are all striving for development. But if developing countries develop to the point of destroying the world economic structure planned by western developed countries, the west can no longer tolerate it. They carefully concocted "protecting the world environment", a fat liar who can go down in history!

In addition, there are more realistic problems. After the American financial crisis, a large number of unemployed people appeared. How to deal with the employment rate is a big problem on Obama's desk. Obama himself is the representative of the blue-collar class, so it is natural to increase workers' jobs. To this end, the United States has made two heavy punches.

The first heavy blow to Japan was the Toyota incident in Japan. By cracking down on Japanese high-end goods such as Toyota, the United States reduced the sales of imported high-end goods, reduced the cost of American goods, and increased the sales and profits of American goods. I don't need to say more about this here. You can find out for yourself.

Second punch, straight to China. Because the increase of industries led by the automobile industry is not enough to meet the employment rate in the United States, nor can it meet Obama's promise to increase 3 million jobs, it is necessary to increase new economic growth points, and the United States has set its goal as a new energy-saving and environmental-friendly industry. However, the United States also wants to ensure that the energy-saving and environmentally-friendly new energy products produced have a market, so the United States has set its goal in China.

First of all, the US feint demands RMB appreciation.

So, what are the benefits of RMB appreciation for the United States? On the surface, this is because the United States is trying to restrict China's exports and make American buyers pay more for cheap goods from China, thus turning their purchasing eyes back to China, so that its own factory will start.

However, this is fatal for China enterprises. As long as the RMB appreciates further by 5-7%, the factories in China will close down, while the United States wants the RMB to appreciate by 30%, which basically means that China enterprises will die.

After that, the United States threatened to label China as a "currency manipulator" and successfully persuaded the European Union to put pressure on China.

However, what the United States has done is not to kill China immediately. His real purpose is to drag China to the negotiating table and increase the bargaining chip.

Sure enough, China really returned to the negotiating table, completely according to the American way of thinking. China and the United States have reached the following understanding.

1, the United States no longer mentions RMB appreciation; 2. The United States is considering recognizing China as a market economy system (clearly, it is considered, and it is not said how long it will be considered); With the contribution of China, the United States "helped" China to build three third-generation nuclear power plants (China already has a safer and more economical fourth-generation nuclear energy product).

Having said that, you should understand that this heavy blow of the United States is actually to find a buyer for American energy-saving and new energy products, and it is to force others to buy them. The Opium War fought by Britain in order to gain commercial privileges in China was essentially no different.

So my point is that the so-called climate crisis does not exist at all, there is confrontation between countries, and politicians are always dark. This is still a world where the law of the jungle prevails. If there is a climate crisis, it means that the economically developed countries led by the United States create the illusion of climate deterioration to exploit our developing countries. In fact, this society is nominally protecting the environment, but in fact it is destroying the environment. The material used in solar panels is polysilicon, which is very harmful to the environment in the manufacturing process. This is the real source of our environmental crisis. The siege of garbage and water pollution are the real culprits that threaten us and nature! Not carbon dioxide.

In order to defend our economy (but not the environment), I suggest that as an ordinary person, what we should do and what we can do to help the country is: under the same conditions, we should try our best to buy domestic goods and spend them in domestic enterprises and businesses, so that people's wealth can stay at home instead of being earned by foreigners. Let our domestic enterprises make more money, so as to give employees more wages. With more wages, they can promote consumption, revitalize China's retail industry and bring China's economy into a virtuous circle. Only in this way can our economy be more developed, everyone in China can benefit, and our country will be more confident in foreign negotiations! As for the environment, I only hope that * * * can solve the water pollution and garbage siege as soon as possible!

Knowledge and opinions are learned, articles are written by oneself, and right and wrong also have their own answers.

What are the causes of global warming? Mainly because human beings have destroyed the natural ecological environment.

A large amount of carbon dioxide emissions lead to global warming.

After global warming, the ice and snow in the North and South poles melt rapidly.

Will lead to global sea level rise. Then by that time, the human housing problem will be more complete.

But as long as we protect the environment, that won't happen.

Physical Geography What are the main causes of global warming? When people burn fossil fuels, such as oil and coal, or cut down forests and burn them, they produce a lot of carbon dioxide, that is, greenhouse gases. These greenhouse gases have a strong permeability to visible light emitted by the sun, but they have a strong absorption to long-wave radiation emitted by the earth, and they can strongly absorb infrared radiation from the ground, leading to an increase in the temperature of the earth, which is the greenhouse effect. Global warming will redistribute global precipitation, melt glaciers and frozen soil and raise sea level, which will not only endanger the balance of natural ecosystems, but also threaten human survival.

On the other hand, due to the greenhouse gas emissions from the land, the temperature in the mainland rises and the temperature difference with the ocean becomes smaller. Recently, the airflow has slowed down, and the smog can't be blown away in a short time, which has led to an increase in smog weather in many cities, affecting human health. Measures such as car restrictions and production suspension have only short-term and regional impacts, and cannot fundamentally change climate warming and smog pollution.

What are the causes of global warming? What are the factors of population explosion? Population explosion is one of the main factors leading to global warming. At the same time, it also seriously threatens the balance between the natural ecological environment. With such a huge population, the amount of carbon dioxide emitted by itself every year will be an amazing number, and the result will directly lead to the continuous increase of carbon dioxide content in the atmosphere, thus directly affecting the climate change on the earth's surface.

Atmospheric environmental pollution factors

The increasingly serious environmental pollution has become a major global problem, and it is also one of the main factors leading to global warming. The research on global climate change in 2 1 century has clearly pointed out that the temperature of the earth's surface has been rising since the end of last century.

Deteriorating factors of marine ecological environment

The change of sea level is on the rise. According to the prediction of relevant experts, the sea level may rise by 50 cm by the middle of the next century. If no measures are taken, it will directly lead to the destruction and pollution of fresh water resources and other adverse consequences. In addition, a large number of toxic chemical wastes and solid wastes produced by land activities are continuously discharged into the sea; Major oil spills in seawater and the destruction of coastal ecological environment by human activities are the main factors leading to the destruction of seawater ecological environment.

Land destruction factors

The main cause of soil erosion and desertification is improper agricultural production. As we all know, good vegetation can prevent soil erosion. However, by the current year of 20 14, due to excessive deforestation, land reclamation for agricultural production and overgrazing, human activities are still seriously destroying vegetation. Land desertification, soil erosion of 47 thousand tons. Soil erosion reduces soil fertility and water retention, thus reducing soil biological productivity and its ability to maintain productivity; It may also lead to large-scale floods and sandstorms, causing huge economic losses to society and deteriorating the ecological environment.

Factors of sharp decline of forest resources

Worldwide, due to natural or man-made factors, the forest area is decreasing sharply.

Hazard factors of acid rain

The influence of acid rain on ecological environment has attracted more and more attention all over the world. Acid rain will destroy forests, acidify lakes and endanger living things. In the 20th century, acid rain around the world was mostly concentrated in Europe and North America, and most of them occurred in developed countries. In some developing countries, acid rain also occurred and developed rapidly.

Accelerated extinction factor

Life on the earth is a precious resource for human beings, and the diversity of life is the basis for human survival and development. But the biological species on the earth are disappearing at an unprecedented rate.

Water pollution factor

According to the water quality monitoring project of Global Environmental Monitoring System, about 65,438+00% of the monitored rivers in the world are polluted. Since the beginning of this century, the water consumption of human beings is increasing rapidly, and the scale of water pollution is also expanding, forming a contradiction between supply and demand of fresh water. Therefore, the treatment of water pollution will be very urgent and important.

Toxic waste pollution factors

More and more toxic chemicals not only pose a serious threat to human survival, but also do harm to the ecological environment on the earth's surface.

The global climate is getting warmer. What are the main reasons for climate warming? What is the greenhouse effect?

What are the main causes of global warming? People cut down a lot of trees to make carbon dioxide exceed a certain content, just like putting a cotton-padded jacket on the earth, which will have a greenhouse effect, the earth will warm up, icebergs will melt, the sea level will rise and the weather will be abnormal. Global warming refers to the increase of global temperature. In recent 100 years, the global average temperature has experienced two fluctuations of cold-warm-cold-warm, which can always be regarded as an upward trend. Since 1980s, the global temperature has obviously increased. 198 1 ~ 1990, the global average temperature increased by 0.48℃ compared with 100 years ago. The main reason for global warming is that humans have used a lot of fossil fuels (such as coal and oil) and released a lot of greenhouse gases, such as carbon dioxide, in the past century. These greenhouse gases are highly permeable to short-wave radiation from the sun and highly absorptive to long-wave radiation reflected from the earth, which is often called the greenhouse effect and leads to global warming. The consequences of global warming will redistribute global precipitation, melt glaciers and frozen soil and raise sea level, which will not only endanger the balance of natural ecosystems, but also threaten human food supply and living environment.

The main causes of global warming are the destruction of the atmosphere, serious pollution and the possible impact of global warming. Global warming will bring complex potential impacts on the earth and human beings, both positive and negative. For example, with the increase of temperature, sub-polar regions may be more suitable for human habitation; Under appropriate conditions, higher carbon dioxide concentration can promote photosynthesis, thus making plants have higher carbon fixation rate, leading to an increase in plant growth, that is, the yield-increasing effect of carbon dioxide, which is a positive impact of global warming. However, compared with the positive impact, the negative impact of global warming on human activities will be more enormous and far-reaching. In August this year, CCTV reported that the summit of Mount Qomolangma dropped by 1.3 meters due to climate warming. Glacier shrinkage in Qilian Mountains endangers Hexi Corridor: In recent years, the melting of glaciers in Qilian Mountains has decreased by about 654.38 billion cubic meters compared with that in 1970s, and the snow line in glacier area is rising at an average annual rate of 2-2.6 meters. According to experts' analysis, in addition to natural climate factors, glacier retreat and snow line rise are mainly caused by population expansion, overload and overgrazing, over-reclamation, deforestation and indiscriminate exploitation of groundwater.
