I believe we are not unfamiliar with the sun. It is a huge star in the center of the solar system, and its mass accounts for 99.86% of the mass of the whole solar system. The huge sun brings strong gravity and makes eight planets and other small planets around it. The sun, due to its internal nuclear fusion reaction, also gives out its own light and heat, bringing a little tenderness to the dark and cold solar system.
Because the distance between the earth and the sun is more appropriate, so there is a suitable light and temperature for the earth, and these light and temperature become the conditions for the birth of life on the earth, so the earth can become a living planet, which is closely related to the sun. The sun is very important for the whole solar system. Its gravity can manage the stars of the whole galaxy and make the solar system have a stable environment.
At the same time, the earth’s life and human survival is inseparable from the sun, once the sun has a problem, such as suddenly disappear, no longer glow, for the earth is absolutely a devastating disaster. It was once proposed that if the sun suddenly disappeared, the fate of mankind and the earth would be doomed, and there was only one way to destroy.
Of course, the sun can not disappear out of thin air, and it will not suddenly no longer glow and heat. Even at the end of life, the sun will still have dazzling light, which is just converted into another kind of celestial body white dwarf. Although the sun will not disappear or no longer glow and heat for no reason, there will still be some problems in the sun, which will bring great disasters to the earth. For example, the reduction of sunspots will bring ice age to the earth.
In fact, in the long period of 4.6 billion years, the earth has experienced several ice ages, each of which lasted for millions of years. At that time, the earth became a frozen planet and a large number of creatures died. Therefore, every ice age will bring a mass extinction.
The reason for the ice age is that the sun has entered a long dormancy period because of the decrease of sunspot activity. The light and temperature of the earth come from the sun. If the sunspot activity decreases and the energy emitted decreases, the energy received by the earth will decrease. The temperature of the earth’s surface will drop sharply, making the earth a world of ice and snow.
In addition to the great ice age, there is also the small ice age. The duration of the small ice age is only a few decades, and the cooling range is limited. However, once the little ice age comes, it will still have a great impact on life on earth, and many creatures will die. However, the time interval of the little ice age is relatively short, which basically occurs every few hundred years or so.
So when will the next ice age come? According to the time cycle, the great ice age will occur about 150 million years ago, while the last great ice age is about 1.75 million years ago. According to this cycle, the next great ice age will take at least 100 million years. Although the great ice age is far away from us, the little ice age is not far away.
The appearance of ice age is determined by the decrease of sunspot activity, so before the coming of the next little ice age, the sunspot activity will have an obvious decreasing trend. Now that human beings have been able to detect and analyze the activities of sunspots, what are the detection results of the detectors?
NASA has publicly said that when the Parker probe circled the sun four times, it found that the number of sunspots’ active range had been significantly reduced, and even the inner part of the sun turned white. This detection of the detector has actually told us that the activity of sunspots is really weakening, and the sun has a tendency to go into dormancy.
Once the sun enters the dormancy period, there will be a little ice age in the future, and the temperature of the earth will continue to decline for decades. So what kind of impact will the arrival of the little ice age have on the earth today? If the little ice age happened before human beings entered the era of science and technology, the impact would be greater. The temperature of the earth would drop a lot. At that time, the food supply would be reduced. Coupled with the lack of effective heating measures, many people might face the threat of death.
However, today’s ecological environment has undergone tremendous changes. The development of industry has produced a lot of carbon dioxide, which has made the greenhouse effect more and more serious. Today’s global temperature has been greatly improved compared with that before the era of science and technology. Moreover, the technology of human beings has also been greatly improved, at least in terms of food and heating.
At this time, if the earth enters the little ice age, it will be a good thing for the earth’s ecology. You know, the rising global temperature is a headache for scientists. We basically have no good measures to stop the rise of global temperature. Even if we take some environmental protection measures, for the sake of the rapid development of science and technology, carbon dioxide emissions will not be reduced.
At present, there is no good way for science and technology to cool the earth, but the power of nature is powerful. The little ice age is a very good natural air conditioner, which can keep the temperature of the earth falling. So once the decades old little ice age comes, the temperature of the earth may return to the last century. This will be a very exciting thing for the earth’s ecology and human beings.
The temperature of the earth has dropped, the melting of global ice and snow has stopped, and the rise of sea level has stopped. The frozen soil layer is frozen again, so there is no need to worry about the resurrection of ancient bacteria and viruses, threatening the earth and human beings. Of course, once the earth’s temperature returns to normal, it will be much colder in winter than it is now.
In fact, cold winter is a good thing. A warm winter like this is not a good thing for the earth’s ecology and human beings, because warm winter can’t kill all kinds of diseases and insect pests, so it’s easy for people to get infected with all kinds of diseases. So we will find that every spring, there are many kinds of influenza viruses, which threaten people’s health.
Thus, the little ice age will be a very good thing for the earth’s ecology. Of course, we are still not sure that the earth has entered the little ice age. Although the number of sunspots has decreased, whether the decrease is accidental or persistent still needs more observation.
The duration of the little ice age can be up to several decades, so the weakening of sunspot activity is also persistent. If the detector does find that the sunspot activity continues to decrease after a long time of observation, then the earth will enter the little ice age. I believe that at that time, scientists will also release such important news to prepare people.
From the perspective of ordinary people, there are expectations and worries about the little ice age, which can cool the earth and make the super high temperature disappear in summer. But in this case, the sharp cooling will still make many people feel uncomfortable, especially in winter, the temperature of dozens of degrees below zero will make today’s young people feel difficult to adapt.
