We are told that increasing CO2 levels cause/are causing the temps to rise, however the geological record shows this to be the opposite. Even if we look at the past 70 years (post 1940) when mans activity is supposed to be most pronounced we find that CO2 has risen for all 70 years but the temps have been either stable or falling for 40 of the 70 years. This would suggest to me that CO2 does not in fact cause the temp to rise but for others this information is of no concern because there is a general agreement amongst some scientists (IPCC) that the opposite is true.
One thing at a time.
We are told that increasing CO2 levels cause/are causing the temps to rise, however the geological record shows this to be the opposite.
The geological record actually does not say anything about what is happening now, this is a very curious thing to say. We know that CO2 levels are rising on their own now, just because they rose as a result of rising temperatures 20K and 120K years ago does not at all contradict anthropogenic global warming theory. (Oh Look!! I called it a theory!)
The geological record is in fact fully compatible with our current understanding of how the climate system works. CO2 did not instigate the warming trend, but CO2’s greenhouse effect is entirely necessary if we want to explain the magnitude of warming and cooling that was repeatedly triggered by tiny orbital focings from Milankovich cycles. It is all explained ad nauseum here atCO2 lags, not leads. And here and here and here.
CO2 has risen for all [past] 70 years but the temps have been either stable or falling for 40 of the 70 years.
CO2 is not the only factor affecting global climate. Regardless, the correlation is quite good over the past 100 years (why did crakar choose 70 I wonder?). The cooling in the mid-century is not without explanation, it is here.
Besides, I don’t find that characterization of the temperature trend very accurate.

this information is of no concern
No. It has been analyzed and understood in the full context of the climate system and our understanding of physical properties of matter. This information was not eagerly seized apon as an excuse to toss out everything we wished we didn’t know and merrily live with our collective heads in the sand, that’s all.
