Why is the earth's climate so abnormal?

All along, both TV stations and textbooks can always see comments calling for human beings to protect the earth, but after so many years, the situation is getting worse and worse. As we all know, Northeast China is the coldest area in China, and it snows early every year. However, this year is very strange. It snows in many places where it doesn't snow in the south, and it doesn't snow in the northeast. It is said that at the end of 20 17, snow began to fall in the northeast.

I don't know if the weather in China is strange, and so is the weather in the United States. It is understood that the temperature in more than 30 cities in the United States has exceeded the lowest temperature in history, and even 22 people have been frozen into ice sculptures. The navy 1 1 aircraft carrier also knelt down collectively and could not move. Generally speaking, the United States is so cold, and Russia should be colder. However, at Christmas, the temperature in Russia is 3.5 degrees, which is unprecedented.

On the other side of the globe, the highest temperature in Australia has reached 47.3 degrees, breaking the record of the highest temperature 80 years ago. The temperature in Washington, USA has dropped to 73.3 degrees below zero. In this way, the temperature difference between the north and the south of the earth has reached more than 120 degrees. What happened to the earth?

The weather has really changed abnormally in recent years. It is undeniable that these changes in the earth are inseparable from human activities. Some human actions have gradually hurt our home. For the sake of the health of the earth, I appeal to everyone to take care of their homes!
