Annual average atmospheric CO 2CO_2 concentrations at eight sites across the globe (data taken from the SIO Air Sampling Network)

The following chart shows the annual change in CO 2CO_2 concentration for Antarctica from the above data set:

The following chart shows the annual change in CO 2CO_2 concentration for the Vostok data set:

Note: The data used for the horizontal axis above is the “Age of Ice”. In some cases, the slope was undefined because the data had the same “Age of Ice” for different depths and different concentrations. Therefore, in such case, an “Age of Ice” was estimated using the nearest “age/depth” estimate.

It may be more appropriate to the use the “Mean Age of Air in the Ice”. The following chart uses “Mean Age of Air in Ice” as the horizontal axis:

Note: No data has been estimated in producing this chart.

Zooming in on the same data set, we see:

The following chart shows the seasonal variations in CO2 concentrations in Antarctica from the SIO data:

The following data compares Mauna Loa, Hawaii and South Pole, Antarctica from the SIO data set:
