Unfortunately, you can't really compare the climate from millions of years ago (along with its CO2 levels) directly to the climate of today.
yes, yes you can.
In the past, the sun put out less energy, there was a great deal of volcanic action, etc.
Yes, and we can account for that. The core samples tell us what was happening. We've already accounted for volcanic action. P.S. Noticed any volcanic action recently?
So, first of all, you say that we can account for these changes. This means you can't directly compare the past climate with the current climate, so you agree with my first point. Second of all, you correctly point out that there hasn't been much volcanic action lately as opposed to the past. The primary effect of volcanoes is to put aerosols into the atmosphere, which cools the earth. (There's also some CO2 emitted, but it's usually pretty small.) So, as you say, the greater volcanic activity tended to cool things off.
If it was believed that CO2 was the only driver of climate, you could compare CO2 levels and make your claim.
Luckily, we're comparing a lot more than CO2 levels. The discussion is not as primitive as you make it out to be to serve your political agenda.
I think you should re-read the post that I replied to. The claim from that post was that you could compare the CO2 levels - and only the CO2 levels - from previous climates and say something intelligent about the current climate. I replied that no you can't, there are many other factors that drive the climate. So now, with your reply, you point out that you agree with everything that I posted. Since you agree with everything I posted and you claim I have a political agenda by discussing actual science and facts and stuff, that must mean that you have a political agenda. What's yours?
