all heat is gained or lost through radiation

Yes, but the greenhouse gasses hinder the radiation of the lower frequency photons (heat). The molecules might just travel up above much of that greenhouse gasses where they would be free to radiate into space, but that is where the atmospheric boundaries get in the way. The molecules are hindered from moving above the jet stream, and they are hindered from radiating through the greenhouse gasses, so they retain more of the heat than they would otherwise.
