So, you want to display the previous 3.1 BILLION years of C02 data and show when the levels were 10 TIMES higher?

I don't think chefantwon has followed this conversation.
The subject shifted to whether humans play a significant role in climate change. I posted the CO2 chart showing the last half-million years in order to demonstrate how CO2 has gone through the roof in the past century, and that this amazing increase has come just as humans became technologically advanced. What, other than human activity, could explain this sudden surge in CO2 over the past 200 years?
Yes, CO2 has been higher in earth's history. And when it was, the climate was significantly different.
The point being made now, which chefantwon has missed, is that with humans adding so much greenhouse gas like CO2 to the atmosphere, we are significantly changing the climate. That's what science is telling us.
