Why is it getting hotter and hotter in summer in recent years?

Although summer heat is normal, the extreme high temperature weather in recent years has made people complain repeatedly, and the main reason for getting hotter in summer is the continuous warming of the climate.

Global warming is the culprit.

1, carbon dioxide emission exceeds the standard.

With the continuous progress of society, the development speed of modern industry is accelerating. Industry is an important source of economic development, but everything has its two sides. With the continuous construction of factories, a large number of harmful gases are discharged into the atmosphere without treatment, of which carbon dioxide emissions are the most. A lot of waste gas is discharged at will, which not only pollutes the air, but also can't release the heat generated by the earth's creatures quickly, resulting in more and more heat accumulated on the earth, warmer climate and higher temperature in summer.

2. Abnormal human activities have surged.

The progress of human civilization is accompanied by the destruction of ecology. Climate warming is undoubtedly caused by human beings! In recent years, with the surge of human activities, glaciers in the Antarctic and Arctic are melting at an accelerated pace, which not only means the rise of sea level, but also brings opportunities for global warming. As an important support for regulating the atmospheric temperature, the melting of glaciers represents the weakening of the atmospheric circulation, and the heat in the atmosphere cannot circulate, which is reflected in the fact that the summer temperature is getting higher and higher and even extreme high temperature weather appears in human life.

3. The "heat island effect" is getting more and more serious.

With the rapid development of the city, many people flock to the city to find jobs and seek survival. However, when there are more people in the city, there will be an embarrassing situation that the demand for housing is in short supply, and the city has to develop new real estate to meet people's housing needs. The land in the city is scarce, and developers can only create unlimited houses in a limited space, so there is a situation in which buildings are built higher and higher and denser. A large number of floating population, tall and dense buildings and glass everywhere make it difficult for the air in the city to flow. When the outside air is difficult to enter and the inside air is difficult to flow out, the "heat island effect" will occur. It is not difficult to find that the temperature in the city is always several degrees higher than that in the countryside, which is more obvious in hot summer!

That's why I think it's getting hotter and hotter in summer these years!
