@farmerman,
CO2 isn't a "contaminant", much else on the ice core is. This isn't directly related, just loved the pic:

I was talking about CO2 in tree rings and I never called it a contaminant, I said that OTHER contaminants were measurable in tree rings.

Neat pic.

@farmerman,
Sorry; glad you love the pic. I wonder how National Geographic makes money - taking that one pic must have cost them an entire expedition escorting the photographer for months.

@High Seas,
Even National Geographic is hurting from a huge drop in the subscription of their magazines. They're offering subscriptions on the cheap - just about pays for the postage.
