Where's the rest of ice core?

Guess it melted... Ice isn't a perfect container, some gasses move freely, like CO2. The longer the air bubble is trapped in the ice, the fewer gasses left to measure and compare. Really old ice wouldn't be useful to promote CO2 levels. Really not sure how they date layers of ice either, since there are usually many events during any year, that can add or subtract ice. Every year we are told about melting arctic ice, 'proving' global warming is a crisis. Basically, it's just another batch of guessing, close enough to use, but doesn't actually have any value, no way to verify. But, if you have faith, and believe everything the IPCC writes, it's easier to accept as 'fact'.

They drill those ice cores out of the ice sheets.

The length of time they cover is the depth to which they can drill and how long ago that particular part of the Earth was in a more or less frozen state.

I'm sure that if you had unlimited knowledge you COULD figure out past CO2 in ice cores but the manner of doing so would be so ridiculously difficult and expensive that only a fool would try.

Anyone know how they are measuring the gasses in those tiny little bubbles, without destroying the ice sample? I'm sure the details of how the testing is done, are available some place. I never really spent much time on ice cores, since I doubt they have much value, except maybe during the warm summer months. Are the tests done at the boring site, or do they transport the core samples half way across the planet? What measures do they take to preserve samples, prevent contamination? How do they keep these samples from being bounced around, or safe from vibrations. Ice is a crystal after all, and room for gasses to escape, if the structure is disturbed. If the sample is destroyed (melted), then it wouldn't be very scientific, since the measurement couldn't be repeated, or verified.

It is pretty straight forward. There are a lot of airbubbles in those ice sheets because it starts out as a covering of either snow or frost. As they are compressed by the weight of successive layers of snow or frost the bubbles supposedly of normal air are trapped in the ice sheet.

So all they do is use a the equivalent of a hypodermic needle to extract the gases in that bubble leaving behind essentially a vacuum and then put that tiny same through a gas chromatograph. I designed at least one version of those instruments.

Don't see how you could have designed one, Wake. You don't know electronics. You don't seem to understand much about light either. My guess is that most your are a script kiddie programmer that likes to claim a lot of stuff he did that he never did.

It is YOU that denies science, Wake. You deny the 2nd law of thermodynamics and the Stefan-Boltzmann law.

It is not my line of work, Wake. I own a company that designs and builds instrumentation for industrial, medical, aerospace, and entertainment markets. I did have to pass an FAA exam for that certification, though. An exam where you couldn't even pass the first question I gave you.
