OK, I found the data that Gore is using:
http://cdiac.esd.ornl.gov/trends/co2/vostok.htm (CO2)
http://cdiac.esd.ornl.gov/trends/tem...k/jouz_tem.htm (temperature)
And a analysis that uses it:

Their conclusion is that it cannot be determined (from the data) that the CO2 data leads or lags the temperature data. I agree. The temperature data has nowhere near the resolution that the CO2 data has. But it should be possible to "degrade" the CO2 data to the level of the temperature data. But still, the number of years represented by the core sampling reolution is problematic. Still, there are analyses indicating an 800 to 1000 year lag (in CO2).

Go ahead and dump the data into excel for yourself. I did. Tom, I am sure you are a smart person. Don't let poiticians fool you.
