Present day treatises dealing with weather and climate often use seemingly physical quantities, while they are in fact averages of such. Inserting these into formulas is physically not permitted. It leads to an assumption of the magnitude of the so-called ‘greenhouse effect’ several tens of K off.
The often-used explanation of the ‘average temperature of the earth’ of 288 K is physically untenable. Another widely accepted property of the greenhouse, the ‘back radiation’, violates elementary thermodynamics. A well-insulated, sun-heated home is a better model. It would diminish the role of atmospheric CO2. Air in general is a fairly strong insulator and also a good heat transporter depending on mass motion and latent heat. The article presents theoretical and experimental arguments in support of these statements.
