Why the theory of AGW is fundamentally wrong in a nutshell

Two most fatal technical errors in current climate research that have led to the false illusion of global warming are comprehensively briefed as follows:

1)  False assumption of a black-body earth surface

Thermal radiation energy per unit time and unit area the Earth emits into space is written as ε σT⁴ , where T is the mean temperature of the earth surface, and σ the Stefan-Boltzmann constant equal to 5.67 x 10^-8 (W/m²K⁴).  

The symbol ε denotes emissivity which has a value between 0 and 1; 0 is for white and transparent bodies, and 1 for black bodies.  Most substances are grey bodies with 0 < ε < 1.  In current climate research, ε is either missing or asserted to be a unit, implying a black-body earth surface.  Truly this is illogically wrong. 

2)         Omission of the thermal emission property of CO₂

We all know that CO₂ absorbs significant amount of earth’s outgoing radiation.  However, this is only half of the story for CO₂.  According to the Kirchhoff’s law of 19^th century physics, an object that absorbs emits.  As a result of emission of thermal radiation, CO₂ is cooler than, gains heat by molecular collision from, and dissipates heat by radiation for nitrogen and oxygen.  It is N₂ and O₂ that award the Earth a warm liveable atmosphere. 

The kingdoms of plantae and animalia, must share the earth atmosphere.  CO₂ is never a pollutant, but a necessity for life.  Increased level of CO₂ concentration is ecologically beneficial, with improved agriculture yields and a greener earth surface coverage due to enhanced efficiency for photosynthesis.
