Local CO2 levels - where is the data?
Regular readers will remember that I highlighted Ernst-Georg Beck's paper and data on 180 Years of atmospheric CO2 Gas Analysis by Chemical Methods which suggested that past CO2 levels varied and were higher than the "official" figures and that the historical figures have been suppressed.
Critics such as Eli Rabett point out :Coby Beck's A Few Things Illconsidered where Coby dealt with Diplom Beck's complete misreading of early CO2 mixing ratio records. If you don't want to go read either post, the measurements were real, but they also were about as irrelevant as measuring CO2 at the top of a smokestack and thinking that it would be representative of the atmosphere. If that does not make sense for you, go read the posts or Charles Keeling's history of the Mauna Loa CO2 measurements.
So the story is that we are to just trust the steadily rising graph from Mauna Loa - local measurements elsewhere are likely to be widely fluctuating especially near conurbations.
I thought it would be interesting to see what some of the many thousand of monitoring stations data looks like to see if they show how unreliable their data is. If they continue to show the sort of variations that Beck found in his historical data that could be compared to the "global figure". Because the variation is meant to be due to local conditions, ie whether the wind is blowing from where the cement plant is, then we should be able to see that the data independently varies. Of course if it is a global phenomenon then it wouldn't. (The graph of CO2 growth also shows a strange variability in rate of growth, some years 1%, some years 3%, why?)
So I started searching and found lots of Google hits for local testing, lots for local emission data but datasets of what the CO2 levels are, I can't find.
(Apart from Phoenix AZ where there is a an urban CO2 Dome which contributes a small amount of warming.)
So where is the data? Surely if you want the good people of say Oxford to cut their CO2 emissions putting "the scores on the doors" would be a good idea. They collect the figures so why is it:
"Statistics on local levels of green house gases such as CO2 levels are not currently available."
I'm not picking on Oxford - the story is the same everywhere I looked - why? What do the figures show?
UPDATE: A comment from Ernst Beck:
Please look at this graph from Schneider at al. ( on my suppl. website).
Modern ice core temperature records vary , the IPCC ones do not. And my
historical CO2 data fit to the varying part, the Mauna Loa do not.
