I couldn't find the link here that talked about this "problem" with the ice data, but I found this "representative sample" that may sound familiar:
http://www.tacticalgamer.com/sandbox/85905-new-global-warming-thread-37.html#post786756Ice Core data suffers from a number of faults. One, ice is not a closed system which is the assumption that must be made in order to accept that the CO2 is trapped. Two, if you take snow from the surface, it will not have a representative amount of CO2 represented even in the cracks. Three, chemical processes still occur deep within the ice always altering the chemical makeup of trapped air bubbles. Four, the pressure differential from being brought from well below the surface to 1 bar pressure causes the air to expand, the ice to break and the air to escape. The ice refreezes with any number of continuing chemical processes that can occur when mixing with our air. Nextly, in order to drill the ice, they use a liquid mud mixture of water, zinc and iron that taints the results. Lastly, scientists knowingly discard outrider data that doesn't fit within their agenda which can be as high as 43% of their data. Source Zbigniew Jaworski They are manipulating the data to drive a result.
With all this anectodal hearsay of the "great variability" in ice core data, I can't figure out why someone hasn't made a name for themselves by publishing evidence on this problem.
Isn't that how people get ahead in science; publish or perish?
...or is this another part of the conspiracy?

p.s. Evidence that these "problems" in ice cores with measuring air bubbles, etc. have been looked into, may be found at:
