You haven't spoken to that question. Nothing in what you posted accounts for your claim that the temp changes 325k years ago were faster and larger (over the same time spans) than the measured recent ones. In addition, your graph shows an extreme anomaly in CO2 accumulation recently - unprecedented in the past half million years. Apparently you think that this CO2 has not had and will not have the effects that ordinary physics and standard climate models predict. Why not? Predictions derived from climate models calibrated by measured data are not blind speculations.
