The continuous extreme high temperature has caused many deaths. What factors lead to the formation of high temperature weather?

The main factors leading to high temperature weather are global warming and greenhouse effect caused by human carbon dioxide emissions, which leads to global warming and temperature rise.

First, the superficial reasons

Judging from the current climate phenomenon, the most intuitive factor affecting the temperature is the atmospheric circulation, that is to say, the reason for the high temperature in China is due to the control of the subtropical high belt in the western Pacific, which will cause high temperature and summer heat in China. The western Pacific subtropical high will stay at sea first, and then move northward along the direct point of the sun. The temperature will rise in all passing areas, and it will continue to rise.

Second, global warming.

On the surface, the subtropical high enveloped China because of atmospheric circulation, but the actual reason was global warming. You know, this tropical high pressure belt will come to China in the past, but it was not so hot in the past. Why is it so hot this year? In fact, it is mainly due to global warming, and the reason for global warming is that carbon emissions are too high, and carbon dioxide emissions are close to 40 billion tons, mainly from the burning of fossil fuels. If we don't promote new energy to change this phenomenon, the earth will only get hotter and hotter.

Third, a vicious circle.

Nature has always had its own biological cycle chain climate and its own climate cycle. If the temperature continues to soften, the ice in the north and south poles will melt, and the melted ice will cause the sea level to rise. Ice has the function of reflecting sunlight. If the sea ice melts, the efficiency of the ocean reflecting sunlight will begin to decline, and the high temperature of the sun will stay on the surface of the earth and cannot be separated from the earth. This result will make the earth's temperature rise again. In addition, there is a large amount of methane in the frozen layer of the north and south poles. Methane is a powerful greenhouse gas. If methane is released, it will cause global warming again.
