How do they know the tempature went up or down during a given period from an Ice core?

One interesting thing is that the Antartic ice apparently stayed put even during the periods of greatest warming. (Or else it would have melted away the record)

      - Yes, maybe temperature has driven CO2 previously? - Sam F. - 1/31/2006 3:27:54 AM
        
        I don't think anyone can answer it. - Tom Brosz - 1/31/2006 5:33:16 PM
        
        It does. It will. It is noted in the literature. - alcaray - 1/31/2006 4:05:07 PM
