It could just as easily have been that different mechanisms caused CO2 to decrease rather than increase. Unfortunately for us, higher temperature does increase CO2 -- which means that by forcing CO2 we're setting up a positive feedback loop.
The atmosphere has more than one effect going on. Adding a new one causes different things than the past ones did.
