How much energy does the earth/atmosphere lose by convection and conduction? Zero, zilch, nada.
And that's the end of the thread right there.
Go home, folks.
How much energy moves from the surface of the earth, through the troposphere, where the climate happens to the stratosphere where it is then radiated out....better than 90%
Energy movement through the troposphere is so completely dominated by conduction and convection that the very idea of a radiative greenhouse effect in the troposphere is laughable.
So much for the end of the conversation...interesting, when you finally say something about the science, you are so far from the mark that one wonders why you didn't just stick to spewing the opinion someone with a political agenda gave you.
