This is a case study report on the actual readings and effects of carbon emmissions. It is a study by Dr. David Evans and his business contact info is included.
Part of this is in original form, but all of it is publicly accessible, thought I would post here, parts are hard to read because of direct quoting; however it shows a clear theory on an effect of our carbon emissions. I agree with the findings. Here is what he says …
The Missing Greenhouse

Introduction
Each possible cause of global warming has a different pattern of where in the planet the warming occurs first and the most. The signature of an increased greenhouse effect is a hotspot about 10 km up in the atmosphere over the tropics. We have been measuring the atmosphere for decades using radiosondes—weather balloons with thermometers that radio back the temperature as the balloon ascends through the atmosphere. They show no hotspot whatsoever. So an increased greenhouse effect is not the cause of the recent global warming. So we now know for sure that carbon emissions are not a significant cause of the global warming.
The Theory
The theoretical signatures come from the latest big report from the IPCC, which is the most authoritative document for those who believe carbon emissions caused global warming. The IPCC Assessment Report 4 (AR4), 2007, Chapter 9. Figure 9.1, in Section 9.2.2.1, page 675, shows six greenhouse signature diagrams.
(By the way, the IPCC omitted signature data for what most skeptics believe is the prime suspect for global warming, namely clouds/cosmic rays/the sun’s magnetic field. Clouds are the main factor that control the earth’s temperature, and are the least understood and most poorly represented factor in the climate models. Cloud formation is strongly affected by the number of high energy cosmic rays falling on the earth, but the sun’s magnetic field shields us from some of these rays. Cosmic rays have a chilling effect on the earth—they cause more low clouds. In periods of higher solar activity the sun’s magnetic field is stronger and shields us from more of these rays, so the earth gets hotter. The earth’s magnetic field is too weak to significantly influence the number of rays striking the earth. Although the correlation between high energy cosmic rays and the earth’s temperature is very high, it is only a correlation and at this stage we cannot prove that this is the cause of the recent global warming. The IPCC focuses only on human emissions of carbon, other greenhouse gases, and industrial pollution as causes of global warming, and vigorously ignores the possibility of solarmagnetic causes.)
The Evidence
The other main authoritative source for the case that carbon emissions caused global warming is the US Climate Change Science Program (CCSP). Atmospheric temperatures have been measured by radiosondes (at all heights) since the 1960s, and by satellites using microwave sensors (up to 5 km) since 1979. The CCSP published the results for 1979 through 1999 in part E of Figure 5.7 in section 5.5 on page 116. The axes and colors are as per the signature diagrams above, except that the horizontal axis only goes from 75 degrees north to 75 degrees south, there is no data around 60 degrees south, the vertical axis only goes up to 24 km, and dark blue above becomes purple here. The data is called the “HadAT2 temperature data”. The observed signature. This diagram is confirmed by more radiosonde data collected after 1999, and also after May 2006 when this diagram was published.
Conclusions
The theoretical combined signature expected by the IPCC contains a prominent and distinct hotpot over the tropics at 8 to 12 kms. This hotspot is the signature feature of an increase in greenhouse warming. The observed signature at 8 to 12 km up over the tropics does not contain a hotspot, not even a little one.
