Pray tell, what IS the correct balance point for atmospheric CO2 concentration? Has that bit of science been settled yet? ;-/

I seem to recall reading that our modern CO2 level is rather low as a function of the geological record, so low indeed that if it had gone much lower there would have been serious curtailment of photosynthesizing organisms everywhere.
