What happened to the weather? It gets weirder every year. Is the earth getting sicker?

If the earth is regarded as a system, this system has evolved for a long time and formed a stable energy exchange system with the outside world, which is a balanced system. When one or more links in the energy exchange system are abnormal or even disordered, the abnormality of the whole system will also occur, and this abnormality is disordered, so it is difficult to form a new balance. There is a problem and the balance is broken, but the new balance is not formed, but in a disorderly state, which brings a series of anomalies, including: 1, global climate anomaly 2, plate movement anomaly 3, ocean current anomaly and so on. All these anomalies, in the final analysis, follow the most basic physical laws, through which a mathematical model can be established, which is the charm of geophysics. The latest research by scientists in China shows that the decrease of vegetation coverage on the earth's surface has an inevitable internal relationship with global climate anomalies. Firstly, the mathematical model is briefly introduced. Background knowledge should first introduce some simple physical knowledge: first, mechanics; Second, Joule's law. British physicist Joule did many experiments. In 1840, he first accurately determined that the heat generated by a current passing through a conductor is proportional to the square of the current and the resistance of the conductor. This law is called Joule's Law. Joule's law can be expressed by the following formula: Q=I2Rt. Third, the photoelectric effect light shines on some substances. This photoelectric change phenomenon is collectively called photoelectric effect. The photoelectric effect can be divided into photoelectron emission, photoconductive effect and photovoltaic effect. The former phenomenon occurs on the surface of an object, which is also called external photoelectric effect. The latter two phenomena occur inside the object, which is called internal photoelectric effect. Hertz discovered the photoelectric effect in 1887, and Einstein was the first to explain it successfully. Fourth, the tip discharge effect is fifth, and the law of electromagnetic induction is sixth. In a word, the concept of field distribution is actually the four mechanics of force, heat, light and electricity, some theories of modern physics, and some knowledge of advanced mathematics and plate movement. Theoretical deduction With this knowledge, we can understand the following sentence (1): The Huang Chi angle of the earth when it revolves around the sun is 23 degrees and 26 minutes. Under the irradiation of solar radiation, the electrons of surface objects are ionized continuously due to photoelectric effect, and the negative ions formed rise with the hot air, making the surface positively charged. The charged amount is linearly related to the intensity and time of solar radiation. In other words, the sun is constantly charging the surface with positive and negative charges. (2) How will the charge be distributed on the surface? Because seawater is a good conductor, in contrast, the continental plate is a bad conductor, so the charge can flow quickly at sea level, but relatively slowly on the mainland. Due to the tip effect, charges will continue to accumulate in higher altitude areas on the earth's surface. Therefore, the total current effect at sea level is zero, and the current effect will mainly be reflected in the continental plate. In this way, the current and charge model of the earth can be established and the distribution can be calculated according to the basic parameters such as the distribution of the earth's plates, the detailed topography of the surface, the rotation of the earth and the angle of solar radiation. Theoretically, the results are very consistent with the actual situation, which depends on the accuracy of parameter selection and the data processing ability of the computer. (3) Current field distribution and geomagnetic field mechanism. According to this theoretical model, if the external solar radiation is completely shielded, the charge on the earth's surface will continuously move to the tip, resulting in a current field of 1, which is called a magnetic field of 1 (this current field is related to the distribution of the surface and the altitude of the land, and the current is isotropic, so its overall effect is zero, but it can be local. At the same time, the earth's surface is constantly discharging, so in the case of solar radiation, the charge distribution on the side facing the sun (mainly distributed in the mainland) is the most in the east and the least in the west (because the earth rotates from west to east), so the current from east to west is formed on the side facing the sun, which is called current distribution 2, and this current generates a magnetic field, which is called magnetic field 2. It can be seen that the magnetic field on the side facing away from the sun is stronger, and the magnetic field on the side facing away from the sun is opposite. In addition, with the rotation of the earth, the magnitude of the magnetic field generated by the positive charges accumulated at the surface tip can be called magnetic field 3; The negative charge on the earth's surface also produces a current field 4 with the rotation of the earth, which corresponds to a magnetic field, which can be called a magnetic field 4. Because the total amount of positive and negative charges is equal, the total effect of magnetic field 3 and magnetic field 4 is zero. To sum up, magnetic field 2 is the main source of geomagnetic field, and the specific data need to be modeled and calculated according to detailed data such as solar radiation and continental plate distribution. (4) How does the Earth achieve charge balance? The earth can be regarded as a super capacitor. While the sun continuously charges the supercapacitor at 1.600 a, it also discharges at 1.600 a (see Feynman Physics Lecture, the average lightning current is 1.600 a, so it can be inferred that the charging current is 1.600 a). This discharge is lightning. Lightning needs to penetrate the air, so it often happens in areas with high air humidity, such as rainy and windy weather and high-altitude crater areas. The electric field intensity on the earth's surface is greater than 100V/m from bottom to top (see Feynman's lectures on physics), and the electric field distribution should be from the surface to the ionosphere. So it can be inferred that the earth's supercapacitor contains a lot of energy. Since there is a lot of charge, why can't we feel it? Because we are at the same potential and dry air is an excellent insulator, we have no feeling. (5) What will happen if the surface vegetation decreases? As can be seen from the above points, the earth's large capacitance is a balanced system. For a long time, the ecological environment and vegetation coverage on the earth are relatively stable, so the water content of the surface is also relatively stable, so the conductivity of the surface is also relatively stable. According to this theory, when the surface vegetation decreases, the surface conductivity decreases, that is, the resistance increases, that is, the internal resistance of the earth capacitor increases, while the charging power, that is, solar radiation, is relatively stable. According to Joule's law, this increases the heat value of the earth's surface to some extent and promotes global warming to some extent. (6) What will happen if the surface vegetation disappears in large quantities or a large area of drought occurs? For example, thousands of kilometers of vegetation in Fiona Fang have disappeared or become dry, resulting in a large area of the surface becoming an insulator, unable to flow according to the original current field, and a large amount of charges are accumulated on the surface. Because of the coulomb force between charges, it is intuitively manifested as the formation of cracks on the land surface, macroscopically as the tension of the continental plate where it is located, and the energy form is elastic potential energy. The longer the drought, the greater the energy accumulation. When the humid air moved to this area, the earth became a good conductor again because of the rain, and a large amount of charges accumulated on the surface quickly moved to the tip, so it rained cats and dogs, accompanied by a lot of lightning, and the energy was released quickly, which caused the abnormal movement of the continental plate. This energy release is insignificant to the earth, but extremely destructive to human beings. From this model, we can know that the decrease of surface vegetation is one of the main driving forces of global climate anomaly. While the surface temperature is rising slowly, various abnormal weather phenomena are becoming more frequent and the interaction is complex, which requires more and more detailed data, such as atmosphere, ocean currents, geology and so on. This model can be used as the basic model of geophysics. The concrete analysis of specific problems can also be extended to other celestial bodies and galaxies. There are two main reasons for uncontrolled human activities. On the one hand, the emission of greenhouse gases causes the greenhouse effect; On the other hand, a large amount of acid rain reduces vegetation and makes the climate abnormal. Edit the countermeasures of global climate anomaly in this section, plant trees, protect the ecological environment, develop new energy, popularize clean energy technology and realize the sustainable development of human civilization.
