Is the earth sick? In recent years, abnormal climate has appeared in many places: short sleeves are worn in Antarctica, and it snows in the desert.

The climate problem of the earth is a top priority for all countries in the world now, and scientists are heartbroken because of the climate problem of the earth.

As for the climate problem, people pay attention to it because the change of the earth's climate will affect the survival of human beings. Only when the temperature of the earth is suitable can human beings survive and multiply, rather than being too cold or too hot.

Although there are three livable planets in the solar system, the temperature and pressure of Venus are too high, just like hell, and human beings can't survive at all. Mars is too desolate, without the protection of magnetic field, all kinds of cosmic rays will directly act on the surface of Mars, and at this stage, human beings can't survive.

Therefore, at this stage, the earth is the only home for mankind. When the earth's climate changes greatly, human beings don't even have a substitute planet to avoid migration, but they can only silently bear the harm brought by climate change to the earth.

It is these reasons that lead to the abnormal change of the earth's climate and affect the nerves of people all over the world. However, according to the data in recent years, unexpected abnormal climate has appeared in many places.

In 20 18, heavy snow fell in the Sahara desert, with a depth of half a meter. A layer of white snow covered the yellow sand, making the arid desert also covered with a layer of silver.

2.5 million years before the formation of the Sahara Desert, as one of the hottest places on the earth, its highest temperature once reached 58℃, which was considered as one of the most unsuitable places for human habitation. It was such a place where it seldom rained that it snowed half a meter deep.

In recent years, it snowed for many years in some areas in the south. There was an interesting story about stealing a snowman, which made northerners laugh their heads off. Can you believe it?

In February, 2020, the highest temperature in the Antarctic was measured at the Lanza Antarctic Research Station in Espe, reaching 18.3.

As one of the coldest places on the earth, the Antarctic has an average annual temperature of -25, and the coldest year has reached more than -50 degrees Celsius. It is precisely because it is too cold that Antarctica has always been a forbidden area for human beings before they entered modern civilization.

However, it is such a refrigerator of the earth, but in recent years, the temperature inconsistent with that of the refrigerator of the earth frequently appears. On March 20 15, the highest temperature in Antarctica was measured, 17.5, but last year, the highest temperature recorded in the Antarctic continent was measured, 18.5, so it is ok to wear short sleeves.

The Arctic Circle, one of the refrigerators on the earth, has hit record highs under a wave of heat waves. After entering July, the highest temperature reached 34. Is this still the North Pole that shivers at the sound of fame?

If these temperature changes are within the range of human tolerance, but some places have abnormal temperatures, then the high temperature in Kuwait will be fatal.

Many people have no idea about this temperature. In the process of food production, there is a practice called slow cooking at low temperature. The temperature is controlled at 60 -70, and it will take some time for cook the meat. It is no exaggeration to say that the extreme weather in Kuwait was directly cooked in the sunshine in Kuwait.

So, is the earth sick? Why are there so many climate anomalies in recent years?

Human intervention theory

It is an indisputable fact that the temperature of the earth is getting higher. Since records began, the average temperature of the earth has risen by about 2.

According to some research models, in the past 200 years, the temperature of the earth has increased, which is related to the trajectory of human activities. The 200 years of rising temperature is also the 200 years of rapid development of earth science and technology.

The development of human science and technology and the explosive growth of population will inevitably increase carbon dioxide emissions, and the increase of carbon dioxide will further aggravate the greenhouse effect.

These statements are the theories that human activities cause the earth's temperature to rise. The core of this statement is that human beings have changed the earth, resulting in changes in the earth's climate.

According to the prediction of this model, with the continuous growth of the earth's population and the increase of demand, the average temperature of the earth will increase to 2 -4 in the middle and lower leaves of this century.

In order to make the earth's temperature rise and control it within an acceptable range, all countries in the world should control the emission of carbon dioxide, and all countries have set targets, that is to say, you can only emit as much as you limit!

I won't elaborate on this. Interested friends can search an interview program of Academician Ding Zhongli, which is very detailed.

Theory of earth cycle change

However, there is still a row of views that the earth's climate change and temperature rise have little to do with human participation, but the earth's climate environment changes periodically.

According to a large number of existing research data, in the Han Dynasty more than 2,000 years ago, the temperature was even hotter than it is now, and human beings in the Han Dynasty were still an inefficient agricultural society. At that time, human intervention in the earth's climate was minimal.

1640, the earth entered the Little Ice Age again, and the average temperature of the earth dropped sharply, making it impossible for nomadic tribes living in the north to survive. In order to seize the living space, they moved to the warmer south. It was during this period that the Ming Dynasty in China clashed with nomadic tribes in the north and perished.

However, during the Little Ice Age, nomadic people living in the north could not survive due to the reduction of crop production, and moved south, resulting in conflicts, which appeared all over the world.

From the hot weather more than 2000 years ago to the Little Ice Age of 1.640, the earth's climate change and temperature change, in fact, the participation of human beings at that time was extremely limited.

It can be seen that the temperature change of the earth is periodic, first hot, then cold and then hot. Now human beings are in a period, which is an interglacial period when the temperature rises after the end of the Little Ice Age.

The main reason for the periodic change of the earth's temperature is related to the activity of sunspots, because the sun is the main heat source of the earth, and the change of the sun directly leads to the change of the earth's surface temperature, and the periodic change of sunspot settlement affects the temperature change of the earth.

Conclusion:

But there is an undeniable fact, whether it is the theory of human intervention or the theory of periodic change of the earth, there is an undeniable fact that the temperature of the earth will rise in the future.

Therefore, in the hot summer, we must do a good job in summer.

Do you think human intervention caused the temperature rise of the earth? Or is the earth's temperature changing periodically, which leads to the temperature rising now?
