Arrhenius vs Ångström vs Stefan-Boltzmann

In our search for the origin of the misinterpretation of Stefan-Boltzmann's Law behind DLR and GHE as two-way heat transfer, we were led to the Swedish meteorologist Anders Ångström. In 1900 his father Knut Ångström expressed strong criticism of the possible warming effect of CO2 suggested by Svante Arrhenius (1896).  In his article Arrhenius referred to Stefan-Boltzmann's  Law with one-way radiative heat transfer from a body temperature T1 to a body of lower temperature T2 being proportional to (T1^4 -T2^4), as illustrated in the following clip with the important qualification of emission into empty space corresponding to T2=0:

Arrhenius thus used a correct version of Stefan-Boltzmann's Law with one-way heat transfer from warm to cold without DLR, while Anders Ångtröm suggested an empirical formula for DLR reminiscent of an incorrect two-way form of Stefan-Boltzmann's Law. Climate alarmism eventually picked up CO2 from Arrhenius and DLR from Anders Ångström.
