What will happen to the earth with more sunspots?

From 180 1, scientists began to study the relationship between sunspots and droughts and floods on the earth, and found that when there were few sunspots that day, some areas had less rainfall and the ground was dry. However, some later statistical studies showed that when there were many sunspots that day, some areas had less rainfall and the ground was dry. It is hard to believe that there is a direct relationship between surface rainfall and solar activity because of the opposite results obtained from statistics in different regions. From a physical point of view, the influence of the sun on the earth is global, and even if it is related, the sun factor is redistributed through the internal factors of the earth.

Solar activity may contribute to human emotions and diseases. The fluctuation of space physical environment coupled with solar activity (energy) and solar-terrestrial energy may affect the physiological functions and diseases of human beings on the ground. Some studies show that the reproduction, development and growth of animals and plants are regulated by solar activities. Some researchers have pointed out that neonatal mortality and the incidence of female diseases are positively correlated with the intensity of sunspot activity. Incidence of some infectious diseases (scarlet fever, diphtheria, dysentery, influenza, etc. ), cardiovascular diseases, eye diseases, etc. Are positively correlated with the intensity of solar activity. However, it should be noted that these effects are not caused by the direct impact of electromagnetic waves and particles radiated by the sun on the ground. Some scientists believe that geomagnetic activity caused by solar storms has a significant modulation effect on human endocrine level, and the human nervous system is very sensitive to geomagnetic disturbance. When the local magnetic activity is strong, the tension of sympathetic nerve in human autonomic nervous system increases, so people's aggressive behavior intensifies, traffic accidents increase and people's judgment errors are on the rise. There are also some scientists and medical scientists who believe that the human body has bioelectricity. EEG, ECG and other testing instruments are also designed accordingly. The bioelectricity of countless cells gathers to form the electromagnetic field of human body. Under normal circumstances, the electromagnetic fields of human body and the earth are in harmony with each other. When the earth's magnetic field is strongly disturbed, it will break the balance between the human electromagnetic field and the earth's electromagnetic field, make some functions of the human body disorder, affect people's emotions and induce diseases.

In recent ten years, the solar activity that caused the most drastic and catastrophic changes in the earth's space environment occurred in1March, 989. At the beginning of March, a huge sunspot group appeared on the surface of the sun, and its area was equivalent to the area of dozens of earths. Dozens of intense flare activities in this sunspot group caused 39 sudden interference of intense short-wave communication, of which 15 was partially interrupted and 24 was completely interrupted. The explosion of this sunspot group threw a large number of high-energy charged particles at the earth, causing a disaster in near-earth space, or satellite orbit space. According to the statistics of American Geophysical Data Center, in March of 1989, 46 cases of satellite anomalies were recorded. The solar storm from this sunspot group reached the earth, causing a strong magnetic storm. This intense solar activity caused power failure in most parts of Quebec, Canada for more than 9 hours, affected 6 million residents, and caused the Quebec Power Company to lose 19400 MW of electricity.

It is for the above reasons that many countries attach great importance to the serious influence and control of solar activities on the earth's environment. Since the 1960s, the structure of solar-terrestrial space weather forecast has been established, relevant research and forecast services have been carried out, and the International Space Environment Service Center headquartered in the United States has been established. There is a 10 regional alarm center. There are the United States, Canada, Russia, Japan, Czechoslovakia, France, India, Australia, Poland and China. With the rise of China's space industry and the development of national defense communication, China started the research and service of solar activity forecast in the late 1960s, which made beneficial contributions to China's space industry and national defense communication. At present, China is organizing relevant units to formulate the Strategic Plan for Space Weather in China. With the progress of science and technology in China, the solar-terrestrial space environment forecast and service will surely make greater contributions to China's space industry and national defense transportation.

But let's not misunderstand, let alone panic. Solar activity will not bring terrible disasters like earthquakes to people who are active on the ground, not to mention the solar explosion that can lead to strong magnetic storms is a rare event.
