What are the main causes of global warming?

Greenhouse effect is a heat preservation effect caused by the lack of heat exchange between the enclosed space for transmitting sunlight and the outside world, that is, the short-wave radiation of the sun can enter the ground through the atmosphere, and the long-wave radiation released after the ground warms is absorbed by substances such as carbon dioxide in the atmosphere, thus producing the effect of atmospheric warming.

Modern industrial society has burned too much coal, oil and natural gas, and a large number of carbon dioxide gas contained in automobile exhaust gas has entered the atmosphere. The greenhouse effect will cause the glaciers on the earth to retreat, the sea level to rise, and the climate zone to move northward, causing ecological problems. In addition, it will cause severe weather changes in some areas in a short time, leading to abnormal climate and aggravating natural disasters such as high temperature, heat wave, tropical storm and tornado.

Solutions to the greenhouse effect

A total ban on CFCs: In fact, the world is working in this direction, and this situation is most likely to be realized. If this can be achieved, it is predicted that global warming can be suppressed by about 3% by 2050.

Countermeasures to protect forests: The global forests dominated by tropical rainforests are being seriously damaged by human beings. On the one hand, the effective countermeasures are to stop this uncontrolled forest destruction as soon as possible, on the other hand, to implement large-scale afforestation and strive to promote forest regeneration.
