If you consider backradiation from the perspective of one GHG molecule it is completely intuitive.
Of course it is, if you disregard the laws of phyiscs.
You guys who believe in QM as if it were law are sad and laughable. Anyone who hangs their hat on QM as it stands today is going to lose thier hat. The statistics of microscopics you believe so strongly in where QM is concerned are actually statistics of statistics...a contradiction...an indication that the statiststics are not to be believed.
Are you aware that QM can't even adequately express the electron cloud around a hydrogen atom? A HYDROGEN ATOM. The most basic of all atoms and QM can't explain its electron cloud without a completely made up "fix". Then QM goes on to fail over and over throughout the periodic table. QM can't even make it through the periodic table and you believe in it strongly enough to disregard the laws of physics.
You are being laughed at.
Net flow is a post modern idea which comes out of QM which is a post modern idea that is riddled with problems and contradictions. It is not proven and remains a somewhat shaky hypothesis.
The only thing the second law says about reverse energy flow is that it can not happen.
The 2ond Law only deals with net flow. Quantum mechanics predicts the reverse flow component of the net flow.
And yet, it is written in absolute terms stating that no sort of energy can move from a high entropy state to a low entropy state. QM isn't the law...QM has barely achieved hypothetical status and certainly has not overturned any physical law. Considering the number of contradictions and outright flaws to be found in QM beginning with its inability to adequately explain the electron cloud around a HYDROGEN ATOM, you may as well believe in the tooth fairy.
