There are many snowstorms this winter. Is there any climate problem behind it? Has the environment improved or deteriorated further?

This sudden cold phenomenon does not mean that the weather has improved this year. On the contrary, it just means that our environment is getting worse. In terms of living environment, relatively stable climatic conditions are needed to ensure normal physiological activities of organisms. For example, it is extremely cold or extremely hot, as in recent years, as it is extremely hot this summer and extremely cold in winter, which is very unfavorable to the normal survival of living things. Judging from the weather situation this year, it should be said that the most direct cause of this abnormal rain and snow temperature is the abnormal atmospheric circulation system, especially since June+10 in 5438, the circulation in the middle and high latitudes is mainly meridional, and cold air activities are frequent. In addition, the subtropical system is strong, northwest than normal, which is conducive to transporting warm and humid air from the south to the north. On the one hand, the cold air in the north is very active, and the warm and humid airflow in the south is constantly transported northward. The intersection of cold and warm air currents is mainly located in the central and eastern regions of China, which creates favorable circulation conditions for large-scale rain and snow weather. In meteorology, this circulation anomaly is generally attributed to two reasons. On the one hand, it is determined by the motion law of the atmosphere itself, on the other hand, it is influenced by external compulsion. This year's circulation anomaly is related to the La Nina event in August 2007. La Nina mentioned here may not be as familiar as El Nino. La Nina, which means "La Nina-"little girl, saint "in Spanish, is the inverse phenomenon of El Ni? o, which refers to the abnormal drop of water temperature in the eastern Pacific near the equator, characterized by obvious cooling in the eastern Pacific and global climate chaos, always appearing after El Ni? o. So both La Nina phenomenon and El Ni? o phenomenon illustrate a problem: that is, our living environment is deteriorating under the destruction of human beings, and nature is constantly sounding the alarm for human beings.

Of course, the occurrence of this phenomenon cannot rule out the influence of solar activity. According to the meteorological records mastered by human beings, it is also a natural law that the earth's temperature changes alternately. However, using the above viewpoints and "accidents" to describe this year's situation cannot completely solve the problem. Necessity is always expressed by chance, and this "chance" is actually the "inevitability" of human destruction of the earth. I hope my answer is helpful to you!
