on a longer term chart we see that co2 levels have at times spiked up to 400 ppmv. And guess what.... there was glaciation.
I just looked this up on the al gore sponsored agw nutter site they say the sun was responsible for the glaciation in that it was 4 percent weaker.
They also advice that there are uncertainties with past data.

Perhaps the co2 helped contributed to the massive glaciation.

Quote from gwb-trading:
Why don't we plot the CO2 range on earth over the past few million years - which would make it obvious that the range over the last 10,000 years is easily within the normal range for the planet.
