We don't need the models. For 20 years CO2 levels have been above anything seen in the ice core data and probably during the entire Quaternary. But the impact on global temps has been slight.

Conclusions any real scientist would make? The models don't work. CO2 is not the driving force behind the warming trend Earth has been experiencing since the end of the last Ice Age.

I can tell you with absolute fact that if CO2 goes below 180 parts per million then plants die.. This has been proven in closed greenhouses. Furthermore greenhouses pump extra CO2 into them to make plants grow faster.

We are at one of the lowest levels of CO2 ever recorded and are in the midst of a 2 million year old ice age. Coincidence?

Without CO2 in the atmosphere we would all be dead. CO2 is Fundamental to life on earth as the only molecule that plant photosynthesis is based on so trying to contain it at its present anemic, unhealthy levels is pure insanity.
