Technically the statement The Earth does not lose heat to space by convection. is false. As the earth travels trough the vacuum of space, matter escapes carrying heat energy. Some of the matter lost got to the place where is could escape by convection. Yeah, mybad for not pointing that meaningless fact out to you. At least you do seem to realise it is insignificant. Excellent! But CO2 does very likely at least slow the rate of heat lost of the Earth by more than that lost by matter escaping. Care to place a W/m2 estimate the above two? CO2 vs gas escaping? The Earth losses most of it's heat by conduction to the air and that air convects that heat to higher altitudes where it radiates. And as it radiates at higher and higher altitudes, there is more atmosphere blocking it's return to Earth than it's escape to space. The "Earth" includes its atmosphere. The Earth cannot lose any heat to itself. It loses almost 100% of it's heat via radiation. End of story. There are all sorts of messy dynamics that affect how the energy finally makes it's way out as radiation. That is what all the good scientists spend their time working out the details on. It is far more complex than just convection in the atmosphere. Things happen on the surface, and oceans as well. Insulation is not a heat source as I and Prof. Dr. GERHARD GERLICH (l) und Dr. RALF D. TSCHEUSCHNER have proclaimed, Insulation and dry air is an great insulator does make for a drastic reduction in heat flow from a warmer place to a colder place. You proclaimed NUMEROUS times on SI that greenhouses were heated by modulating convection. What a fool.
