Although this matter has been carefully examined in the three valuable papers by H. Craig, R. Revelle -H. Suess, and J. Arnold-E. Anderson, on the exchanges of CO, between atmosphere and oceans, in the February issue of Tellus’,Qpages I to 32, there is one point on which I may be able to throw some further light.
This point is the large discrepancy between recently measured depressions of the radio-carbon activity, (known as the “Suess effect”), and the appa- rent increase in atmospheric CO, as given by measurements of this quantity between 1870 and 1935, (CALLENDA19R40). Both Revelle and Suess, p. 2 5 , and Arnold and Anderson, p. 31, consider that no increase as large as the 10% indicated by the latter measurements could actually have occured in such a period, in view of the size of the active CO, exchange reservoirs shown by their measure- ments. However, they suggest other factors which might conceivably account for the discrepancy.
CO2 and climate
- [Callendar 1958]
Of late years there has been much interest in the effect of human activities on the natural circulation of carbon. This demands a knowledge of the amount of CO2 in atmosphere both now and in the immediate past. Here the average amount obtained by 30 of the most extensive series of observations between 1866 and 1956 is presented, and the reliability of the 19th century measurements discussed. A base value of 290 p.p.m. is proposed for the year 1900. Since then the observations show a rising trend which is similar in amount to the addition from fuel combustion. This result is not in accordance with recent radio carbon data, but the reasons for the discrepancy are obscure, and it is concluded that much further observational data is required to clarify this problem. Some old values, showing a remarkable fall of CO2 in high southern latitudes, are assembled for comparison with the anticipated new measurements, to be taken in this zone during the Geophysical Year.

Just because the data values are unique and possible, based on the region's climatology, does not guarantee that they are correct, for there are many types of errors that can occur during all stages of processing
