Carbon dioxide absorbs infrared radiation (IR) in three narrow bands of wavelengths, which are 2.7, 4.3 and 15 micrometers (µM). This means that most of the heat producing radiation escapes it. About 8% of the available black body radiation is picked up by these "fingerprint" frequencies of CO2. Climate scientists know that more CO2 does not result in more heat under usual conditions. So the mythologists among them try to salvage the global warming propaganda by pretending that something esoteric occurs higher in the atmosphere. The difference is that the absorption peaks for CO2 separate from the peaks for water vapor. Then supposedly, radiation which misses CO2 does not get picked up by water vapor and travels into outer space; and more CO2 causes less radiation to get missed on the shoulders of the peak

I'm with you on this. I've been arguing this point for years but most people have no clue about absorption and emission spectra. CO2 does have some emission bands like 10.2 µM that may play a part, but the emission is too weak given its small percentage of the atmospheric makeup. I've argued that for CO2 to be a significant contributor to heat gain in the system would put its concentration above lethal limits for animal life. None of this warming garbage stands up to the physics. It's just packaged pseudoscience fear mongering propaganda that the masses will buy into. CO2 is not a threat.

CO2 is not a threat.

It's plant food

Nothing I said contradicts this, fam. Just making another point bolstering argument against the whole global warming hypothesis.

As we are leaving an ice age still the globe is supposed to be changing it always changes, no humans needed. I think its the point that man made global warming, is as currently portrayed a hoax, an important distinction.
