Then there are the articles by Lawrence Solomon, and his Wikipedia woes, that started me reading the comment pages on Wiki a bit more carefully.
The measured global temperature record which started around 1856 shows that the Earth was in a warming cycle until around 1880. The CO2 record shows that CO2 was increasing by about 0.21ppmv/year over this period.
During the cooling cycle which followed from 1880 to 1910, the CO2 concentration increased at a rate of about 0.30ppmv/year.
The next warming cycle from 1910 to 1942 saw a dramatic increase in global temperature, but the rate of increase in CO2 concentration only grew to 0.33ppmv over this time period.
The well documented global cooling period from 1942 to 1975 that had the world concerned about an impending return to the equivalent of the Little Ice Age, had a contemporaneous rise in atmospheric CO2 that equated to 0.63ppmv/year; almost twice the increase in CO2 of the precious warming cycle.
During the warming that took place from 1975 to 1998, the rate of CO2 increase took another dramatic jump to 1.54ppmv/year, but this was followed by an increase to 1.91ppmv/year that we are currently experiencing during the present ongoing cooling cycle.
Each successive cooling cycle has had an increase in the rate of CO2 growth over the previous warming cycle, indicating that there is no possible correlation of CO2 with global warming.
