Andre, this is mainly concerning your work, especially with your claim that CO2 is not a gas that causes global warming. From what I have gathered (and I hope I don't make a fool of myself by saying this) but you have argued that CO2 levels have risen over periods of cooling in the past, correct?
I was wondering about the effects of clouds, I have done some basic calculations about the overall effect of clouds on global warming and it I concluded that clouds would cause a net cooling (I might elaborate if probed but it's probably been done more vigorously by someon more qualified so it would be nice if someone could verify this for me). Anyway, it seems that clouds would also cause a drop in photosynthesis and thus an increase in CO2, right?
So is it not possible that in the past cooling due to an increase in cloud cover (possibly caused by a variety of mechanisms eg increased volcanism, forest fires etc..) would have been met with an increase in CO2. Would this not explain the apparent disparity in the records? Therefore we should be cautious when looking at the past records and saying that CO2 is not a significant greenhouse gas, it may simply have not appeared to be significant because of the clouds!
