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 19th 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.
