I wonder why the weather is always changeable as usual.

The title should always be "Nothing"! The doomsday theory is exaggerated. The end of the world will come, which no one can predict. But don't worry, you and I will never see each other in my life. The end of the earth will eventually be caused by two reasons: one is man-made disaster. Over-exploitation and environmental destruction of human beings have exhausted energy and made it impossible for human beings to survive on this planet. Second, natural disasters. The unpredictable planetary movements of alien planets repeat the same mistakes and stage a disaster blockbuster of extinction in the dinosaur era.

The reason why the weather is changeable now is a natural phenomenon, and there are not many cases that violate the laws of nature. The heat, cold, rain, snow, wind and frost never stop. It's just that the news was blocked before, and there were too many things we didn't know, just like mine accidents. It seems a lot now, but in fact it was more before, and the news was blocked. You don't know! Don't worry, you will be happy all your life!
