What was the chief culprit in the Little Ice Age? Can you tell me?

I wonder if you have observed the sun carefully. Sometimes the surface of the sun is particularly bright, which is the darkness of the sun. If you look at the surface of the sun carefully, you will find that some places are darker than others. Sometimes you can even see the surface of the sun suddenly brighten. These are what we call sunspots and solar flares, and they were also the chief culprits of the Little Ice Age. Let's discuss this problem together today.

Flare, generally refers to solar flare. Flare is a sudden flash phenomenon observed on the disk or edge of the sun, which releases huge energy as high as 6× 1025 Joule. They are usually, but not always, accompanied by coronal mass ejections. Flares throw clouds of electrons, ions and atoms in the corona into space. The sun is a bright and hot dense gas cloud with great pressure inside. Sometimes the pressure becomes too great. Therefore, the sun must release some energy. When the sun does this, some areas of the surface become brighter. These bright areas are called solar flares. Solar flares usually occur in the active area on the surface of the sun, surrounded by sunspots, which is a high magnetic active area on the surface of the sun. Although they emit light, they are not as bright as the surrounding areas, so sunspots look darker.

They are actually colder than other parts of the sun. When the sun occurs, it also releases different kinds of energy particles, such as electromagnetic energy and electron ions. These particles usually reach the earth in a day or two, but don't worry, they won't hurt us because we are protected by the earth's atmosphere. This is an electromagnetic field. Sunspots were observed in ancient times. At that time, people noticed these changes by observing sunspots and realized that the sun must be spinning. Aurora borealis, usually called the Northern Lights, is caused by the solar wind hitting the earth's atmosphere. As early as 364 BC, astronomers in China observed sunspots.
