Pawn, if the only variable is CO2 concentration, then as a general rule I agree with you, however there is still an optimum CO2 level which I think is around 1000ppm CO2, current CO2 is around 420 ppm ish. I have read that a few plant species don't actually benefit from increased CO2 but have not managed to find what the optimum concentration of CO2 for them is, could be even lower than current levels. But the discussion was on the wider impact to the climate, for which we have seen and are now experiencing a great deal of change, as I have already stated, partly due to human activity and partly due to natural phenomena and this was part of the reason for me posting the link about wells that are running dry.
Pawn your latest post again contains another statement without context... the direct impact of CO2, i.e. the amount of CO2 in the atmosphere and its physiological effects may not be a problem as animals can cope with breathing in the increased CO2 quantity however the secondary impact that the increased CO2 is causing is a different matter. Just as an aside there is always an exception to the rule and those animals currently living in environments with extremely low levels of oxygen will be impacted more by slight rises in CO2.
We could get into a discussion about the average temperature of the sea increasing, or the retreat of snow/ice, revealing black stone underneath, the melting of the permafrost and subsequent release of methane into the atmosphere, the reduction in biodiversity, I think that in the UK alone there have been over 400 species of plants and animals made extinct and that there are simply too many people on the planet but again digressing from the chat on PRD.
AndroclesB, I was merely pointing out that various points of view or arguments were being made without any context, it wasn't just you.
GRH, Thank you for answering the questions I had the other week, my apologise for the delay.
As for your most recent post, in order to bring things a little back on topic, yes it can be seen that identical plant genus' living under different atmospheric/climactic, soil conditions will have different characteristics when analysed, for instance leaf size, types of and quantity of chlorophyll, as one will have grown in what may be considered a relatively more stressful environment to the other.
