BRAY, J.R. "An Analysis of the Possible Recent Change in Atmospheric Carbon Dioxide Concentration" in "Tellus, a Quarterly Journal of Geophysics". Svenska Geofysiska Foreningen. Stockholm, Esselte AB, Vol 11, 1959, with the Bray on pp 220-230 in the volume of 489pp. Provenance: Metecrologisk Institut, with their oval rubberstamp on the front pastedown and on the title page. 24x18 cm. Bound in half-cloth and marbled boards. FINE copy. [++] This is a major paper in the history global warming, measuring CO2 and its historical (pre- and post-industrial revolution) existence in the atmosphere and finding increased values in the majority of samples. [++] Criteria minimizing differences in operators, location, and time of observation are established for selecting comparative data on atmospheric CO2 concentration during the past 100 years. The resulting selection showed in all cases the period 1907 1956 to have a higher mean than 1857 1906. The difference between means was not statistically significant for 5 unweighted comparisons. Weighting by estimates of reliability resulted in a significant difference for yearly and summer non-urban values, but not for the other 3 comparisons. Additional comparisons of all values in the study, of six entire distributions, and of five paired studies with closely comparable data showed increases in a more recent period, with one exception. The magnitude of the increase for weighted yearly non-urban data was 25 ppm (from 294 to 319) for the quarters 1857 1881 to 1932 1956. Several possible explanations for the increase include: 1) an actual atmospheric increase, 2) a coincidence of the influence of micro-atmospheres, 3) improvement (or change) in chemical technique. --abstract from this paper.
