It seems that when it comes to 15 micron IR, people focus too much on absorption from earth warmth. A few hundred meters above the earth the air is swarming with 15 micron IR that does not come from the earth, but comes indirectly from collisions. That IR is the energy that escapes earth. SSDD and his minions do not understand that.

Any actual evidence? Didn't think so...and what exactly makes you think that energy transferred via collision is 15 micron? 15 micron describes radiation...energy transferred via collision is not radiation....
so I'm still wondering about these losers on here stating greenhouse blah, blah, blah and that IR is emitted back to the surface to warm it. If they are all now acknowledging that CO2 loses most of what it absorbs during collisions and that less than 1% of CO2 actually emits, where does all their magic IR toward the surface come from now? these folks are truly confused with their religion.
Wow. That went right over your head. As I said, you and your minions don't understand it. You got that two step process mixed up. I thought you already understood that 15 micron radiation excites a vibration mode in CO2. That vibration is kinetic energy. That kinetic energy of vibration is generally lost to collision with an air molecule. It's really quite simple!
What do you think generally happens with the 15 micron radiation absorbed by CO2.
