When was the Little Ice Age? If so, what should we do?

The Little Ice Age means that the temperature on the earth has dropped, a very big drop, and the extent of this drop is usually 10 degrees to 20 degrees at the lowest temperature. For example, there was a little ice age in the Qing Dynasty, and most parts of northern China could reach MINUS 30 degrees or even MINUS 40 degrees, but now the temperature in the northeast is just that.

The emergence of the Little Ice Age was because the rotation of the earth or the solar system entered the spiral arms of the Milky Way. We all know that the earth goes around the sun and the solar system goes around the Milky Way. This is the relationship between small galaxies and large galaxies. Small galaxies are naturally the solar system, and large galaxies are the Milky Way. There are many similar galaxies in the Milky Way. When small galaxies gather together, there will be related gravitational changes, which will lead to the reduction of solar radiation, that is, the reduction of energy, and then it will appear on the earth.

Although it has an impact on people's lives now, it is not as obvious as it was in ancient times. At least, the corresponding heating equipment we have now is developed enough, but it has dropped by 10 degrees or 20 degrees. Even if the winter temperature in the north reaches MINUS 30 degrees, people can still live normally, just add some warm clothes, and then consume more energy for indoor warmth, which will not cause any danger to life. However, the Ming and Qing dynasties still had a great influence, because not everyone could afford coal at that time, and there was no such perfect warm-keeping equipment now, so many people froze to death because of the cold, and this will not happen now.

This is a periodic change in the operation of the universe, and we can't change it. What we can do is to adapt, because the Little Ice Age will not cause great changes in the biological environment on the earth, at least not to say that from our normal temperature fluctuation range, from MINUS 20 degrees to MINUS 40 degrees, it will suddenly become a temperature of above 60 degrees or even higher, and it will not drop too much. Therefore, as long as we actively respond to changes in climate conditions, human survival will not be a problem.
