Here’s some more for the AGW disbelievers, but I’ll need Ludwig to complete it.

An object like the Earth will reach equilibrium between the energy it absorbs (e.g. from the Sun) and creates (e.g. from burning fossil fuels, nuclear power, etc.; all energy ends up as heat), and the energy it radiates back into space.
Objects the temperature of the Earth emit infrared. Since CO2 absorbs infrared, it prevents that energy from being radiated into space. Instead, it heats the atmosphere.
Eventually, the Earth will heat to the point where it emits at wavelengths that aren’t absorbed as well, and then return to equilibrium, but at a higher temparature than before.

Now, here’s the part I don’t know. At what wavelength does CO2 transmit enough energy to stop the warming, and what black-body temperature does that correspond to?
I do believe it is uncomfortably warm.
