In general there are in physics infinitely many incorrect explanations of a given phenomenon, but only one which is correct and then serves both the people and the educated.
In literature you find many descriptions of unhappiness, but few about happiness. Failure is more frequent than success.
In (democratic) politics, the people decide the truth because they are many. In science, one enligthened is enough to decide the truth. Scientific truth is not determined by consensus of the majority: to refer to "scientific consensus" is not a scientific argument.
You find in climate science several explanations of a so-called greenhouse effect, from elementary for the people to advanced for the educated:
The popular explanation is:
- CO2 is a "greenhouse gas" with an ability to "trap heat".
- More CO2 "traps more heat" and thus warms the Earth.
- The atmosphere cools the Earth by emission to space from a certain "characteristic emission level/altitude" at a "characteristic emission temperature" determined by Stephan-Boltzmann's Radiation Law (SB).
- More CO2 will "lift" the characteristic emisson level to a higher altitude.
- Higher altitude means lower temperature, because the temperature drops with altitude according to a certain lapse rate.
- Lower temperature means less radiation according to SB, thus with less radiation out than in.
- Radiative balance is restored by shifting the whole temperature profile causing warming on the Earth surface and restoring the characteristic emission temperature.
- The net effect is 1.2 C warming upon doubling of CO2.
