The classical interactions in gravity and in electrostatics have been revisited in (1-4) and it follows that the temperatures in black body equilibrium are taken into account for the neutral and charged masses. This new conception of the black body radiations effects in photonic fields which are superimposed in the structure of space-time in quantum entities EVTD2 requires that inside the entities exist material elements (concretizing the intimate substrate of space-time) to capture and store these electromagnetic energies, which were originally named "Substratum" (5). These Substrata corpuscles would be correlated with the positive and negative pressures where the attractive and repulsive effects are generated in the new conceptions of gravity and electrostatics. So, this Substratum subjected to positive pressures would be a good sensor of electrostatic energy (photons) but also a good provider of returned caloric energy, for example in greenhouse effects for its atmospheric environment if necessary. These are the starting points for a certain understanding of the different greenhouse effect yields of CO2 and CH4 molecules, whose RECH4 / RECO2 ratio is recognized as being in the neighborhood of 25. We must therefore determine what is the common and quantifiable correlation between these molecules that makes it possible to approximate it to 25. It is a question here of determining, at best, the respective intrinsic and adapted volumes of compliant energy storage of these two gases.
