Bush was horrible, but Gore would have been worse

the environment of an ice core might be subject to variables we aren't even aware of yet.

interesting... well, the only difference is the ice...
and we know from modern chemistry that when it comes to solids with thermodynamically-important imperfections, like ice, the molecules periodically (though rarely) liquefy and then immediately recrystallize, making the case that tiny amounts of CO2 could possibly dissolve from a gas mixture into a contact layer of water ice, and then slowly diffuse through the interior of the crystal lattice. however, the amount would be a tiny fraction of the CO2 concentration in trapped air. and if this was really happening, then the CO2 levels in the trapped air would decrease vs the increasing age of the sampled ice - but the relationship between sample age and CO2 concentration is almost perfectly harmonic.
