BTW
even if the chart were actually giving an accurate depiction of earth's CO2 levels--which I don't believe for a moment it is.
So the icecore data is made up? Even though it is supported by numerous other studies? Can you back this up with anything more than your say so?
You need to learn that just because you would like something to be true doesnt mean it is true- and when you challenge scientific data you need to provide more in the way of argument than "I dont believe it".
