Global Warming, page-254

Hi Dertz, i am not sure where you are headed with this. I am familiar with firning and vostok. In fact it is because of firning and vostock i became a sceptic.
Anyway, i think we are in agreeance that vostock is at a minimum using a 1000 year moving average. I thought / think it is/was several thousand years. But 1000 years is plenty.. That 1000 year moving average number alone would indicate that 280ppm is not really the maximum that it peaked at ?
