Thanks Bert,
Your graph demonstrates what we have been talking about, CO2 levels have risen exponentially in recent times, and the temperature rise reached has plateau of between +/- 2 degrees of the 0 mark.
Statistics mean what you want them to mean. Have you demonstrated the link between rising CO2 and temperature?
We are not saying that CO2 hasn't risen, we are asking for the relevance of the statement in regards to global temperature change, and is it Mans fault, or something else not being represented? The conjecture is in the research of the "something else", not enough work has been done on that portion, and that is where the sceptisism comes from.
You asked earlier for a list of people who fall into the sceptics arena - can you please discredit these people for us?

And just to put my "ulterior motives" on the table, I personally benefit from the rising CO2 argument in relation to IT power comsumption. The corporate line and my line diverge significantly as to the relevance.
