text: The Earth system is not analogous to a house being heated with a furnace running at -18 degrees C, which temperature then gets amplified to +15 degrees C by insulation or backradiation or heat trapping. In fact, your furnace in your house doesnt even work like this. In fact, nothing anywhere works like this because it is a violation of thermodynamics. The greenhouse effect models have to violate thermodynamics because the people creating them never go back to think about whether they are conserving energy vs. flux, and whether or not they are conserving physics. These details havent apparently appealed to them.
