Why doesn't it feel cold this year?

First, in the long run, global warming is an indisputable fact.

I remember when I was a child, it snowed heavily in winter, the wind was biting and it was very cold. It began to snow in June165438+1October, and it often snowed ten centimeters and twenty centimeters thick. But now it can't snow once or twice a year in our Dabie Mountain area, and it's only a thin layer every time. It is an indisputable fact that the weather is getting warmer and warmer now. According to the analysis of meteorological data and statistical data over the years, the whole world is warming. So it makes sense not to feel cold in winter now.

Second, in the short term, the lack of cold this winter is caused by the El Ni? o phenomenon.

Since the summer and autumn of this year, affected by the El Ni? o phenomenon, there has been continuous high temperature and dry weather, especially in the Yangtze River basin, which has not happened for decades. Just two days ago, we also carried out artificial rainfall in Anhui, because it hasn't rained for several months. Affected by the Pacific Rim climate, the weather is dry and the temperature is rising, so this winter is not particularly cold. However, it has not yet entered the real cold, just saying that the temperature is a little higher than normal. When it is in a cold winter, the temperature may drop or a cold wave may appear.

Thirdly, the industrial pollution of automobile exhaust is also an important reason for the high temperature.

We all know that there are a large number of cars in the city now, and their exhaust gas has a serious impact on the environment. Dust, waste gas and other pollutants in archways in various industrial production processes will also pollute the atmosphere. These waste gases and dust float in the air, which will form a kind of heat insulation and protection layer, and the temperature and heat absorbed by the earth's surface in summer and autumn can not be dissipated in time, thus forming a greenhouse effect. This is also an important reason why winter is not particularly cold now.
