Historically CO2 levels did lag temperatures by an 800 year period. This doesn't negate the fact that CO2 is a greenhouse gas. In fact, the reason for the lag is quite obvious (to anyone but a GW denialist, that is): an enhanced greenhouse effect wasn't the initial cause of the warming (the reason CO2 levels eventually rose is because CO2 is less soluble in warm water, and as the oceans warmed, they released some of their vast stores of CO2). This is a completely different scenario than what we have today because CO2 *did* rise before temperatures this time (and thus this warming bears all the signs of an enhanced greenhouse effect).
Radiative physics dictates that carbon dioxide act as a greenhouse gas, and that increasing its concentration in the atmosphere necessarily increases the planet's temperature. You can quibble about the details all you want, but the fact that human activities are having some effect on the climate is indisputable.
