Globally, electromagnetic Energy-thermal-flows from a hot body to a cool body/environment as per the Laws of thermodynamics. Then how is it that there is no Outflow of em energy from the earth out despite a well defined down Temperature gradient from the core to the surface and out? as per geophysicists, the earth maintains a strict Radiation balance -- i.e., the earth neither gains nor loses any em energy net. Is this an unsolved paradox?
