Why do extreme cold weather occur every once in a while around the world?

In our nature, with the change of some meteorology or some phenomena, there will often be a sharp change in temperature, so the most concerned issue in recent years is global warming. Although it is said that the global climate is warming, it does not rule out that it will appear in many places in a short time and the weather is very cold. Then, because most parts of the whole earth are in a state of global warming, it doesn't mean that all places are in a state of rest. So why are there some places that are extremely cold in the case of global warming? What is the reason for this phenomenon? Even what we need to explore needs to be compared.

Because of global warming, the temperature in some places has dropped sharply, which may affect the surrounding environment, so this is what we need to pay attention to. As far as the surface area of our whole earth is concerned, then our global climate is gradually darkening, so it is a little higher than the surface temperature of the previous earth. Relatively speaking, it is in a steady and continuous rise, so the temperature should maintain a stable trend. Then his theoretical difference or his actual difference will not be great, just like when our human body temperature is slightly higher or lower, it may be within the normal fluctuation range.

Although the global climate is warming as a whole, the earth is divided into many plates or places, such as the South Pole or the North Pole, and the temperature in each place fluctuates too much compared with other places, such as the high temperature in some places. In other places, its temperature may be lower than that in quiet places, so although the global temperature rises again. Then, in some places, there will be a situation in which the weather turns sharply for a short time.

The earth is our home, so everything on the earth is the product of nature. The earth is the most suitable planet for our human existence among all the planets. Therefore, no matter its temperature and humidity or its environment for human adaptation, it is very stable and more suitable for human habitation. However, although its overall temperature is relatively stable, when this stability is destroyed, there may be two extreme States, such as the South Pole and the North Pole.
