Just as a reminder of what makes up our atmosphere for people that have been fed that CO2 dominates our environment now. Our atmosphere is made up of the following:
78% nitrogen
21% oxygen
1% other gases (CO2 among them)
If you want to know what the real greenhouse gas is, it is actually H2O with CO2 not even being technically significant in comparison. Friggen idiot people of the world, wake up already!!!!
