Paleoclimatology can't provide that. The reason is proxies with decent granularity like ice cores have poor correlation to temperature. So while an ice core is pretty good for telling you about CO2 changes over a 50 year interval 40k years ago, so what? It tells you little about temperature. OTOH, the temperature proxies like sea creatures embedded tell you a lot about sea temperature, but have very poor granularity. So you won't find out anything about a 50 year period, or even very much within a 1000 year period 40k years ago.
Your implication is of course correct, a 50 blip of warming like we see today is part of natural variation and it takes unnatural manipulation (i.e. smoothing in Mann's hockey stick) to make it appear abnormal.
Thanks for giving me the science behind what we know.
I knew the concept but not the details.
