Well RL FYI, I have had this idea for more than two decades.
And I apologize if the *slight* that I made so many years ago caused some confusion in your brain.
It does not take mathematics to understand that *radioactivity* can raise the temperature of the surrounding material, and it does not take math to understand that nuclear detonations have enough energy to accelerate air molecule into outer space, specifically if the detonations are conducted in the upper atmosphere. Only commonsense is needed to understand that if *heat* is *created* and if the *cause* of the heat lasts for thousands of years and this *heat* is continually added to the environment, then the environment will get hotter even if the input is small compared to the size of the planet. It is also obvious that *extra* heat in the environment will eventually be very inconvenient if not deadly to people
