The more complex answer is that for a given wavelength of light (λ), a material can absorb (αλ), reflect(ρλ), and/or transmit(τλ) a fraction of the energy in the wavelength, and the sum of αλ+ρλ+τλ = 1.
the answer is ‘yes’ to what? I understand that CO2 can absorb then retransmit heat back to earth, however, it is very inefficient, and only a very small part of the heat is released back towards earth- most likely to be cooled on it’s return trip- only a small fraction of heat would be sent reflected back- and the other point is that our atmosphere is only 0.04% CO2- that number is far too small and insignificant to even cause any kind of heat trapping to begin with- IF the atmosphere were I dunno, 50% or more CO2, then yeah- you’d be seeing isolated pockets around the globe that would see a rise in mean temperatures because of REFLECTED heat, but you wouldn’t see universal global rise in temperatures everywhere- there would be large swaths of atmosphere with no CO2, and heat would be escaping through these holes still-
I’m at a loss as to how just 0.04% of the atmosphere can cause global warming- it seems very illogical to claim that man is 100% responsible for global warming as the warmists claim when man is only responsible for 3.4% of 0.04% of the total CO2 I n the atmosphere- that’s akin to claiming thaqt someone sneezing in china is causing hurricanes in the US
