But the point is that we don't know what those readings mean, nor what they indicate in regards to current CO2 readings (or CO2 readings from other times). The issue isn't even accurate data of one sort or another, but how it all relates to climate change now, and how that all affects climate change from the past. Which we have no accurate way of reading.
However, that all being said, we should get our act together and go green tech now. There is significant data over the past 50-100 years to indicate that our CO2 production is doing something bad, and that the temperature is rising, on a global scale. Some data out there say that we are in fact forestalling another ice age, one that is 1,000 (iirc) years past-due.
