I have no idea what kind of axe you have to grind here, but of course it's extrapolation and approximation. What else do you expect, SD Cards with digital weather records from 10k years ago buried into the ground? The point is that many people who are much more familiar with the subject than us two seem to agree that the extrapolation is accurate enough to draw certain conclusions from. If you aren't too busy with your ad hominem attacks then it would be nice if you could make a factual point beyond "Wikipedia is wrong" and "The climate research community is wrong". What exactly are they doing wrong? If you could get an accurate reading on the global temperature from one location than why do we bother with all the weather stations? Well, I think we do the ice thing to learn about the time before we had weather stations. Also all it takes is a look at the TOC of that wikipedia page to notice they're using not one but dozens of core sites on multiple continents. I'm almost sure they're not extrapolating from just a single block of ice, as you're trying to suggest here...
