Falsification Of The Atmospheric CO2 Greenhouse Effects Within The Frame Of Physics [PDF]

, 2009
The atmospheric greenhouse effect, an idea that many authors trace back to the traditional works of Fourier (1824), Tyndall (1861), and Arrhenius (1896), and which is still supported in global climatology, essentially describes a fictitious mechanism, in
