"How high have co2 levels been in geologic past and did the temps lead or lag co2 from ice core reconstructions?" Try Google for CO2 levels. As to leading or lagging, well, in the natural processes, something starts the warming trend. Once the warming starts, the melting of tundra, drying of peat bogs, etc. released CO2 and methane, which kicks the process in high gear. What we never had in the past was a species that heavily tapped fossil carbon like we do know. So analogies with the past are not one to one.
