How to use thermodynamic knowledge to explain global warming

Global warming is not a simple thermodynamic problem. The earth is not a closed system, let alone an adiabatic system. Therefore, the problem cannot be considered using a simple thermodynamic system, such as the entropy increase mentioned below.

The earth is an open system for energy. The surface absorbs short-wave radiation from the sun and then emits long-wave infrared radiation to the atmosphere. It is the main source of atmospheric energy. After the atmosphere absorbs short-wave radiation from the sun and long-wave radiation from the ground, Atmospheric long-wave radiation is released, part of which is released back to space, and part of which returns to the ground. This is the heat preservation process of the earth's atmosphere, which is the greenhouse effect. Without the greenhouse effect, there would be no life on earth. As fossil fuels burn and emit too much carbon dioxide, the greenhouse effect increases, but the earth has various mechanisms to balance the greenhouse effect, such as reflection from cloud tops and the effect of sand and dust. Greenhouse gas emissions do not cause acid rain. The main cause of acid rain is sulfur dioxide produced during the combustion of sulfur compounds contained in fossil fuels. As the greenhouse effect intensifies and global warming occurs, the atmospheric water cycle will become more intense, and more water will reach arid areas. Without human destruction, vegetation coverage will increase. For example, the Jurassic was much warmer than it is now. Vegetation cover is also much better.
