Dude, they’re so confused, they think conducting is IR. Too funny!!!In post 257 you said,If the CO2 loses most of it's energy by colliding with O2 or N2, that means the air must heat up. Right? You better tell Billy that.
No one ever said that air couldn't warm via conduction...It is IR that can't warm the air. And no matter how you spin and interpret, you simply can't make a radiative greenhouse effect out of conduction.
the time between molecular collisions is so much shorter than the time it takes a molecule to absorb radiation and then emit it that most molecules capable of absorbing IR lose it to oxygen or nitrogen molecules via collision before they have time to radiate it on to space.You directly say most green house molecules loose their absorbed IR energy to O2 or N2 via collision. The gain of energy by O2 and N2. is called thermal energy because it is random. So the atmosphere is warmed by CO2 which gains energy by IR. Therefore the premise of this thread is wrong according to you.
It doesn't matter what form the energy was when it was absorbed...when it is lost via collision, it is not IR...Twist and gyrate all you like...but it is conduction that moves the vast bulk of energy through the atmosphere...and it is via water vapor...not CO2...CO2 is barely a trace gas and is completely overwhelmed by water vapor.
