Among other things, we know about diffusion, the gaussian filter effect that takes out short term variability that might explain the smooth ice core data, etc., but when taking readings from the air samples in ice, what is the mechanism for accounting for the CO2 contained in the ice itself?

When sceptics look at statistical data, whether it is recent ice melt, deep sea temperatures, current trend in global surface temperatures, troposphere temperatures, ice core records etc. they look at the data as it is without any pre-conceptions and describe what it says.

Nancy Bertler explains how ice cores are analysed and how data from ice cores helps scientists to understand what Earth's climate was like in the past, over the last million years or so.

What matters is not the warming rate since the mid-19th century but the fact that ice core data reveal the existence of a quasi-millenarian (natural) oscillation, that well correlates with observed (mean) warming observed since the mid-19th century.

exactly... i recall seeing a graph produced from ice core samples in which the CO2 content of thousands of years past was measured against tree ring data... what it showed was CO2 levels rising 300 years after rapid vegetative growth (natural warming) and incidently the PPM of CO2 measured higher than current levels.

It is possible to do this with ice core data, and what is found is the maximum correlation extends out to around 800 years or so:

I spent a week listening to 80 paleoclimatoligists and climate modelers argue about the interpretation of the data from ice and sediment cores, how it eliminated some proposed explanations for what was driving the changes in temperature and rainfall, and how it suggested other possible explanations.

An important point, which we have discussed elsewhere on attribution of CO2 in the Ice Cores, when comparing data looking for signals, is that we are making reasonable assumptions about what we would expect to see before we looking at the data.

Ice core data shows that this is what happens.

What all of this «data» leaves out is the tree - ring minima and ice core acidity peaks that, when integrated with other regional and global climatological events stretching back, at the very least, to 4375 BCE, present a picture of some kind of cyclical, apparently cosmically induced climate cycle.

The difference between ice core measurements and proxy data (like stomata data) is that with proper equipment and handling, the ice cores give a rather good sample of the real atmosphere of many years to milennia ago, while proxies need some translation between what you measure and ancient reality...

It is not possible to calculate the effect of anthropogenic CO2 until we know within closer limits what the natural variation is.For example if you look at the ice core data for the Holocene and if you believe that CO2 is the climate driver you would have to conclude that on a scale of thousands of years CO2 was an Ice House — not a green house gas.For the data and an estimate of the coming cooling for the next few hundred years check the post» Climate Forecasting for Britain's Seven Alarmist Scientists and for UK Politicians.&raqice core data for the Holocene and if you believe that CO2 is the climate driver you would have to conclude that on a scale of thousands of years CO2 was an Ice House — not a green house gas.For the data and an estimate of the coming cooling for the next few hundred years check the post» Climate Forecasting for Britain's Seven Alarmist Scientists and for UK Politicians.&raqIce House — not a green house gas.For the data and an estimate of the coming cooling for the next few hundred years check the post» Climate Forecasting for Britain's Seven Alarmist Scientists and for UK Politicians.»
