Why is there a saying that the hotter the summer, the colder the winter ... The greenhouse effect will not only increase the temperature. ....

In addition to the greenhouse effect, there is also the sunshade effect. It is said that the hot weather in summer makes the glaciers in the North and South poles melt, and the result of melting is to emit a lot of cold air. In winter, the rapid spread of cold air leads to too cold weather in winter and the global temperature drops. So these years will be hot in summer and cold in winter.
