You appear to be assuming that the curves represented by the studies I indicated represent the real and moment-by-moment temperature variations in the past. They are not. The charts I indicated are averages over long periods of time, obviously, and there's likely a lot of noise in the original data that won't appear on charts spanning millions of years. We don't have any reliable data on how quickly temperature changes happened in the geological past except on gross scales. For short time scales, we have no reason to believe the temperatures didn't vary as rapidly in the past as what we're seeing today, much of that variability would just be noise, and only over the long term would trends emerge. Thus we still have no basis for knowing that what we're seeing today is unprecedented.
