Even the Vostok or Dome C ice cores over the past 420 kyr or 800 kyr have sufficient resolution to show an increase of 100 ppmv over 100 years (and down again in 100 years?)

The resolution is 8 years over the past 150 years, 40 years over the past 1,000 years, 80 years over the past 70,000 years and about 560 years for the past 800,000 years (Dome C used smaller samples than Vostok).

Further, there is firm evidence that migration of CO2 isn't important in the Vostok and Dome C ice cores over the past 800,000 years: each glacial / interglacial period shows the same ratio between temperature and CO2 changes: about 8 ppmv/degr.C.

As far as the correlation between GHGs and temperature goes, recent history already passes his r2 > 0.5 test with flying colours - the Mauna Loa CO2 data vs GISTEMP from 1961 - 2004 gets r2 = 0.76, and I'm sure that the Vostok ice core data must be in the same ballpark over ~ 400,000 years or more (a quick google finds multiple references to the strong correlation but no hard numbers and I can't be bothered doing it myself).

For instance the Vostok ice - core data over 415,000 years has an average measurement - spacing of 756 years, meaning that the likelihood of measuring an increase in atmospheric CO2 as the one measured at Mauna Loa over the last 50 years, if one existed in the Vostok ice - core samples, amounts to 6.6 % (i.e. 50/756).

And of course, there is the Vostok data, which shows the historical warming and cooling behavior in a single location but over 100 year periods.
