Okay.

We've been hearing a great deal about ice core readings, and how the long millennia of relaxed ice core CO2 numbers has suddenly spiked in our time.

I've managed to crack Figure 8 loose and reprint it below. I've taken the liberty of recalibrating the ice core readings on the right to (roughly) match the CO2 scale on the left (red line.)

Get it now? And check out the spike at about 12,700 BP.

        It sounds to me like Hansen's right on. - ER - 5/20/2013 5:29:18 PM
- The CO2 is increasing. - ER - 5/19/2013 7:33:15 PM
  - I'm not saying it isn't. - RobVG - 5/19/2013 8:49:37 PM

        You brought up ice cores, not me. - ER - 5/20/2013 5:55:18 AM
        
        Don't bother. - TB - 5/20/2013 3:37:09 PM
        
        I don't recall ever quoting any ice-core data. - ER - 5/20/2013 4:01:43 PM
        
        Sorry, wasn't clear. - TB - 5/20/2013 4:24:43 PM
