Just to make sure everyone is aware of all the evidence:

In particular this video specifically sites a paper that explains the current ice core record:
The simple and brief answer is that historically orbital factors have initiated changes in global temperatures. When an increase in temperature was initiated the decreased solubility of CO2 in the warmer oceans caused a release of CO2 that enhanced the relatively weak orbital forcing. This is why in the ice record the CO2 lags the temperature changes. However, it is well known that the orbital factors are not strong enough to account for the observed temperature changes. In fact because it was known that orbital forcing wasn't enough it was actually predicted that the ice record should show a lag between CO2 and temperature for the reasons above before it was actually observed experimentally. We also happen to know that no such orbital forcing is occurring today thus the current rise in CO2 is not only because of us but is also doing exactly what it was always known to do. It just so happens that this time the instigating cause is different.
