Short answer: Absorption / emission of light. The atmosphere gets thick enough that the oxygen and nitrogen there absorb UV-C and more energetic light, ozone absorbs UV-B (from above) and some infrared (both from above and below, ozone is a greenhouse gas). Where there is little ozone, there is little indication of temperature.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
