Oh, you mean science fair experiments like the one Bill Nye had to fake?
Nye screwed up on that. But there were better constructed experiments that show that CO2 raised the temperature within a container compared to a control container.
You also seem to be one who believes CO2 that absorbs LW radiation cannot turn it to heat.
The reason that the air heats up near the earth (or in a controlled experiment) is given by these simple steps:
- Black body radiation from the earth is absorbed by the GHGs in the atmosphere.
- The absorbed energy becomes vibrational energy of the GHG molecules.
- The vibrating GHG molecules will largely hit random air molecules and transfer the vibrational to kinetic energy.
- Gain of random energy by air molecules is thermal energy, or heat.
- That energy gain in the atmosphere must be equal to the earth radiation energy absorption. (conservation of energy)
That simple physics shows a coherent link between the absorption of IR by a gas and warming in the atmosphere. If you disagree with that, which of the 5 steps do you think is wrong.
