Another View on Climate

My Own View of Global Warming

CO2 Has Been Higher in the Recent Past

Posted by greg2213 on January 15, 2010

Recent, in this context, is over the last 180 years. Prior to putting a CO2 monitoring station on an active, CO2 spewing volcano, scientists used other methods. Those methods are detailed in a draft paper by Ernst-Georg Beck.

Here are the first three points of his summary

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.

The rest is here
