There is no independently verifiable evidence that CO2 is the cause of the slight warming that has occurred since the Little Ice Age in the real atmosphere. There is a slight Linear+Cyclic Warming since at least the 1880, 132, years ago and significantly despite CO2 being pumped out in vastly increased quantities since the 1940s/50s the temperature has not deviated from the slight Linear+Cyclic Warming. CO2 has not caused Temperature to deviate!
To show warming is not to show the cause of the warning. That is the mistake you alarmists make. You think that the warming is the whole ball of wax. It isn't since you've not shown causation in the REAL ACTUAL ATMOSPHERE.
Girma Orssengo's analyses using the standard observational temperature and CO2 data sets shows that Mother Nature has falsified the alleged CAGW Hypothesis. It's well worth your time to comprehend this elegant and clear analysis.
" *Effect Of CO2 Emission On Global Mean Temperature*
Examination of Figure 3 shows that the Global Mean Temperature Anomaly (GMTA) for 1940 of 0.13 deg C is greater than that for 1880 of –0.22 deg C. Also, the GMTA for 2000 of 0.48 deg C is greater than that for 1940 of 0.13 deg C. This means that the GMTA value, when the oscillating anomaly is at its maximum, increases in every new cycle. Is this global warming caused by human emission of CO2?
The data required to establish the effect of CO2 emission on global mean temperature already exist. The global mean temperature data are available from the Climate Research Unit of the Hadley Centre shown in Figure 3, and the CO2 emission data are available from the Carbon Dioxide Information Analysis Centre [8]. *For the period from 1880 to 1940, the average emission of CO2 was about 0.8 G-ton, and the increase in the GMTA was 0.13+0.22=0.35 deg C. For the period from 1940 to 2000, the average emission of CO2 was about 4 G-ton, but the increase in GMTA was the same 0.48-0.13=0.35 deg C. This means that an increase in CO2 emission by 4/0.8=5-fold has no effect in the increase in the GMTA. This conclusively proves that the effect of 20th century human emission of CO2 on global mean temperature is nil.*
*Note that the increase in GMTA of 0.35 deg C from 1880 to 1940 (or from 1940 to 2000) in a 60 year period has a warming rate of 0.35/60=0.0058 deg per year, which is the slope of the linear anomaly given by Equation 1. As a result, the linear anomaly is not affected by CO2 emission. Obviously, as the oscillating anomaly is cyclic, it is not related to the 5-fold increase in human emission of CO2.
Figure 4, with high correlation coefficient of 0.88, shows the important result that the observed GMTA can be modeled by a combination of a linear and sinusoidal pattern given by Equation 3. This single GMTA pattern that was valid in the period from 1880 to 1940 was also valid in the period from 1940 to 2000 after about 5-fold increase in human emission of CO2. As a result, the effect of human emission of CO2 on GMTA is nil.* "

Furthermore the conclusive counter evidence analysis based upon *observational data* by Girma Orrsenago puts a nail in the coffin of the AGW Hypothesis as promoted by the CO2 Climate Doomsday AGW Rapture proponents. *Orrsenago shows that Nature falsified the CAGW hypothesis*.
Hole in Man Made Global Warming.
a) Global Mean temperature (GMT) => http://bit.ly/zISeEo
For the period from 1880 to 1940, GMT increased by about 0.35.
For the period from 1940 to 2000, GMT increased by about nearly the same 0.35.
b) Human CO2 emission => http://bit.ly/wD1SZj
For the period from 1880 to 1940, CO2 emission increased by about 150 G-ton.
For the period from 1940 to 2000, CO2 emission increased by about 840 G-ton.
How come the increase in CO2 emission by 460% has not caused any change in the GMT?
