I searched for a message board about global warming after I saw "The inconvenient truth" because I noticed something about the graph and this is one of the forums that came up that looked interesting.

Anyways, I posted my question and it's on the environment board if anybody is interested. What I noticed basically is that he never gave a current temp graph to correspond with his CO2 graph because to do so would show a gross flattening of temp. This is based on his unit of measurement of "pleasant day on the high side of temp and "buried beneath a mile of ice" for the low temp. Using this unit of measurement and ascribing the unit of 80 degrees as a typical "pleasant day", it would have to be 240 degrees at this time of year in our northern cities that he is speaking of if it is to correspond to his CO2 line for this time. Up until this point, he shows a correlation between the two lines.

I've watched several videos countering the theory that GW is being caused by humans spewing CO2 into the atmosphere and I cannot find this particular error in his graph being discussed. It's not in anything I've read yet either.
