But before explaining what those are I’d like to clear a misunderstanding: By implying or inferring that my claims have no bearing on the fact that nuclear fission disturbs or increases the kinetic energy of its surroundings, you are ignoring facts.

Since you have not specifically said so, I have to assume that you agree with me that nuclear fission can increase the kinetic energy of the surroundings.

From information on this web site: https://www.webelements.com/carbon/isotopes.html
There seems to be seven radioactive carbon isotopes that have a half life decay time ranging from .127 seconds to 5715 years.

“At present, we have identified something like 2600 nuclides: 260 stable nuclides, 25 very long-lived naturally occurring radionuclides, and more than 2300 man-made radionuclides.”

I also agree with you that pollution of the atmosphere by carbon based gasses can affect the temperature of the atmosphere. My only concern is that no one seems to be investigating the effects that these radioactive contaminates, that have been spread over the whole planet over many years, is doing to the environment.
I have yet to find information, even a scientific estimate, of the total quantity of radioactive carbon isotopes or man-made radionuclides in the atmosphere. I know that you say it ranges from nonexistent to miniscule and you can find pie charts that enforce your belief.

So; I am going to abandon my quest in this area for the time being. Have a good day and keep away from the pollution. (It may fry your brain further.)
