Just something to counteract Algore's claim that CO2 level's haven't changed in the past million years (until now) based on ice core samples..

This is just the past 450k years..

Actually, he didn't say they haven't changed, he said CO2 is higher than it's ever been.

It's worse (for Gore) than your chart shows. See Myth: The most CO2 in 650,000 years for more info.
