Sure, CO2 radiates heat, but along with that scientific paper people have never posted is the fact that if CO2 is bombarded with the type of radiation it is said to like, that radiation is absorbed, dispersed, weakened, the word is you do not get more going in than you get coming out,
But we do get more going in than coming out. The satellites measure it. It's why the world is warming. We measure the outgoing infrared energy squeezing down in the greenhouse gas absorption bands, as AGW theory predicts. Smoking gun #1.
We also directly measure downward longwave radiation -- that is, backradiation -- increasing. Again, as AGW theory predicts. Smoking gun #2.
Currently, AGW theory is the only explanation for such changes in the heat flow balance of the earth. If you've got a different way to explain it, write it up, publish, and collect your Nobel Prize.
so we are to believe that the evil heat is amplified, not weakened as it bounces around in the atmosphere?
From here on, you're babbling nonsense. You don't have the physics background or the common sense to understand what's going on. There's nothing wrong with not understanding a field, as long as you understand your own limitations. However, if you think your own failure to understand means the rest of the world is all wrong and engaging in fraud, you've crossed the line into belligerent ignorance and conspiracy retardation, and that is a problem.
