You are correct heat loss happens over distances and time this is a law of thermodynamics. Once energy hits the initial particle of our atmosphere and hits our surface, thats the hottest it can be. each subsequent bounce is less hot since the energy (heat) transfer happened. I think the Globo model also seems to think that we live in a closed system which we dont. heat sheds into space not just towards the planet.
The original models, to show warming over time, had to collect heat in the upper armosphere. Essentially, there is a "lid" in the models that only let a static amount of heat through (the calculated energy budget of our heat loss to space is generally use as this lid) which is how we "warmed".
Newer models get more creative, hiding heat in the oceans and such.
