Abstract: The greenhouse effect has being widely concerned around the world, and it is nearly defined as the physical mechanism that greenhouse gases absorb and emit infrared radiation.
However, this definition is deviation from the original physical fact, because the Earth’s atmosphere is not equal to a greenhouse with glass roof. And because the main constituents (such as nitrogen, oxygen) of the atmosphere don’t absorb infrared radiation, the temperature of the whole atmosphere cannot be elevated.
Here, by analysing the cardinal mistakes of the current atmospheric physics, the very physical mechanism of the greenhouse effect is discovered. Only the intermolecular collisions can cause the absorbed energy to be shared with the other, non-IR-active, gases, so that the whole atmosphere is warmed.
The absorption and re-radiation of greenhouse gases can make the radiant energy be reserved in the atmosphere in longer period of time, so that the greenhouse effect is maintained and enhanced. The phase change radiation and its proofs are introduced into the atmospheric physics, which shows that the heat diffusion equation of vapour condensation and the cloud formation on adiabatic expansion are false.
The greenhouse effects of water vapor and carbon dioxide are compared, which shows that the effect of carbon dioxide is so little as to be ignored and the effects of cloud cannot only be covered under the concept of feedbacks. The urban heat island effect is reasonably explained. The possibility of the global warming predicted by the Intergovernmental Panel on Climate Change is evaluated to be impossible.
