Why does weather affect the transition between Ming and Qing Dynasties?

According to ancient records, in 1550, during the Jiajing period of the Ming Dynasty. From this time on, the earth entered a particularly cold period, which lasted for 300 years. Not only is it cold in the north, but even Fujian and Guangdong are experiencing extremely cold and severe weather.

We all know that Guangdong is a subtropical coastal area, with the Tropic of Cancer passing through its central and southern parts. It has an oceanic subtropical monsoon climate, which is mainly warm and rainy.

But there was extremely bad weather here at that time. The rivers froze, the cold meant drought, and the low precipitation weather caused a devastating blow to the farmers' crops at that time, prompting the farmers at that time to have no harvest for several years. , hungry and cold, suffering numerous casualties. Social phenomena such as peasant uprisings caused by famine followed one after another and had a great impact. These events are also recorded in history books.

The bad weather also indirectly became the culprit of the replacement of Ming and Qing Dynasties! During the 17 years of his reign, Emperor Chongzhen, the last emperor of the Ming Dynasty, encountered a once-in-a-thousand-year drought and plague. The Ming Dynasty was overwhelmed by internal and external troubles. Seeing that there was no hope of survival, the hungry peasants rebelled one after another. Under the attack of multiple natural and man-made disasters, the Ming Dynasty perished.

According to historical records, hundreds of millions of people died in China between the mid-15th century and the mid-18th century. Therefore, the population after the founding of New China was actually not large.
