Thanks for the explanation Ziggurat.

It makes perfect sense... heat gets trapped in the atmosphere due to the composition of high CO2 and the atmospheric pressure forces that heat to escalate until it hits its maximum based on physical laws. At that point the temperature is maintained.

Sounds like Venus is sitting on an equilibrium to me...

But here's my next question :

What causes Venus' atmospheric pressure to be so much higher than ours ? Rotation ? Axis tilt ? Direction of revolution ? Atmospheric composition ?

Could that answer the question of what our maximum temps could possibly reach in a worst case scenario if CO2 jacks up to 95% here on earth...? Of course the differences of our hydrological cycle, etc would all have to be factored in as well in order to calculate max temp possibilities.

Or am I completely off my crock thinking of it this way ?
