Dutchroll,
If you look at the graph i provided earlier which correlates temperature to CO2 over 800,000 years you will see the last 50,000 years there has been a sharp increase in core sample temperature. This suggest that we are indeed in an overall warming phase. There has been a mild plateau for the last 10 thousand years and are mildly cooler then 6000 years ago but its a minute step in the historical cycle. In the past CO2 has followed temperature because of the nature of the environment. There is still no proof it is forcing temperature rise.
