180 Years accurate CO2 - Gas Analysis of Air
Summary
Accurate chemical CO2 gas analyses of air over 180 years show a different trend compared to the literature of IPCC climate change actually published. From 1829 the concentration of carbon dioxide of air in the northern hemisphere fell down from a value of e.g. 400 ppm up to 1900 to less than 300 ppm rising till 1942 to more than 400 ppm. After that maximum it fell down to e.g. 350 ppm and rose again till today, 2006 to 380 ppm. Accurate measurements had been done amongst others by de Saussure 1826, Pettenkofer/v.Gilm 1857, Schulze 1864/71, Farsky 1874, Uffelmann 1886, Letts und Blake 1897, Krogh and Haldane 1904, Benedict 1912, Lundegardh 1920, van Slyke 1929, Dürst and Kreutz 1934 alternatively 1940, Misra 1942 or Scholander 1946 with measuring instruments through which from 1857 (Pettenkofer) an accuracy of +/-0,0006 Vol% to under +/-0,0003 Vol% =~3 ppm (Lundegardh 1926) was achieved. These pioneers of chemistry, biology, botany, medicine and physiology constituted the modern knowledge of metabolism, nutrition science, biochemistry and ecology. Modern climatology ignored their work till today even though it is the basis of all textbooks of the mentioned faculties and was honoured with several Nobel prizes. In total over 90 000 measurements within nearly every year since 180 year gave the following results:
1. There is no constant exponential rising CO2-concentration since preindustrial times but a varying CO2-content of air following the climate. E.G. around 1940 there was a maximum of CO2 of at least 420 ppm, before 1875 there was also a maximum.
2. Historical air analysis by chemical means do not prove a preindustrial CO2-concentration of 285 ppm (IPCC),as modern climatology postulates. In contrast the average in the 19th century in northern hemisphere is 321 ppm and in the 20th century 338 ppm.
3. Todays CO2 value of. 380 ppm, which is considered as threatening has been known several times in the last 200 years, in the 20 th century around 1942 and before 1870 in the 19th century. The maximum CO2-concentration in the 20th century roses to over 420 pmm in 1942.
4. Accurate measurements of CO2 air gas contents had been done from 1857 by chemical methods with a systematical error of maximal 3%. These results were ignored reconstructing the CO2 concentration of air in modern warm period.
5. Callendar and Keeling were the most important founders of the modern greenhouse theory (IPCC) beside Arrhenius. Literature research confirmed that they ignored a big part of available technical papars and selected only a few values to get a validation of their hypothesis of fuel burning induced rise of CO2 in air. Furthermore these authors discussed and reproduced the few selected historic results by chemical methods in a faulty way and propagated an unfounded view of the quality of these methods, without having dealt with its chemical basis.
6. To reconstruct the modern CO2 concentration of air icecores from Antarctica had been used. The presented reconstructions are obviously not accurate enough to show the several variations of carbon dioxide in northern hemisphere.

It is easily seen that
1. atmospheric carbon dioxide fluctuates through 19th and 20th century contradicting the icecore reconstructions.
2. In 20th century we notice one big maximum around 1942 with more than 420 ppm and several little maxima in 1915 and 1905; in 19th century a big maximum occurred before 1870 and perhaps a big maximum in 1820 out of precise measurement area. Little maxima appeared around 1876, 1880 and 1890.
3. CO2 concentrations rises from approx. 1880 to 1930 by some 20 ppm as Callendar speculated in 1938.
4. Big maximas with an amplitude of 100 ppm like the one in the 40s should be easily reproduced with chemical methods (3%). This is not mentioned in modern literature.
Notice how on this graph the rise in CO2 concentration, beginning around 1920 and peaking around 1942 at 440 ppm, lags behind the rise in temperature which begins around 1910. It should be the other way round according to the proponents of the bogus AGW hypothesis.
