The reason has to do with the fact that the warmings take about 5000 years to be complete. The lag is only 800 years. All that the lag shows is that CO2 did not cause the first 800 years of warming, out of the 5000 year trend. The other 4200 years of warming could in fact have been caused by CO2, as far as we can tell from this ice core data.

That is a pro global warming site.
Until we see further evidence, neither you, scientists, Gore, nor and I have any proof that man is causing global warming.
