The laws of thermodynamics I see the proof of the "greenhouse effect" as follows ... The approximations are... heating by tidal effects are ignored, internal heating radioactive decay is ignored. Not a big deal from first glance. The temperature of the planet is assumed to be only that generated by the flux of energy from the sun. Statement (4) says the maximum temperature of the surface is calculated by the T4 law. The second law of thermodynamics states (in very brief form) heat energy runs from hot to cold, not the other way around. If an atmosphere is added to a planet with a surface temperature of 225 K (-18 deg C) the maximum temperature of the atmosphere will be, assuming MAXIMUM mixing and total convection of gases with the surface of the planet is... 225K (-18 deg C) Now do you get it? It's not "rocket science". No other considerations are necessary. Basic High school physics. The ONLY WAY the temperature of the planet to exceed 225K (-18 deg C) is by some other heating method. This is the Greenhouse Effect. Is that clear enough for you?
