It appears that he actually believes that greenhouse gasses increase the energy coming in from the sun. If we could only put that magic to use in a real way, our energy problem would be solved
Any time energy as heat flows through a system there is a temperature gradient. Different conditions cause differences in the gradient. CO2 reduces the ability to shed energy at the surface/atmosphere boundary. This energy that is not lost immediately to space accumulates and temperature rises to a new equilibrium. This is not new energy, it is redistributed energy. Space is cooler, the surface boundary is warmer. Once equilibrium is reached the input matches the output, as it was before CO2 changed the conditions.
