Lastly, of course, there is Beck’s paper, which is essential reading on this subject. I do not have Beck’s data, just the ice core data: some of the same signals, though not the same in magnitude, in the CDIAC data are also in Beck. His contention, supported by data, is that CO2 has been higher in the recent past. Like a peak around 1940 or so, declining afterwards: the decrease we also see.

Ooooh, now what. Can humans be blamed for co2 depletion?

Bob,
You’re right about human population v. fossil fuel use. I meant to imply that as the population increases, so does the use of fossil fuels, but, of course, not necessarily at the same rates. I did not do a good job of explaining this.
And you’re also right that I did not directly answer the questions; at least in a satisfactory way. So I may go back and change some of the text to say this: yes, at times, CO2 concentrations has gone down—if the ice core data is accurate, or if Beck’s and Jaworowski’s criticisms are valid.

Completely separately, I noticed in the World News section of the DT last Saturday that a Norwegian testing station had measured the current CO2 in the atmosphere at 394 ppm !!!!! (as you know it is currently supposed to be 381 ppm ‘ish).

Unfotunately the DT gave no further link & I’ve been unable to verify any details but overall I don’t mpkdavies’ conclusions are very valid. (as usual).
