See: The AGW Smoking Gun By Gary Thompson
The science behind the AGW hypothesis is that increased amounts of CO2 in the atmosphere (that humans produce by burning fossil fuels) will block more outgoing long-wave IR radiation (OLR) from exiting the atmosphere and thereby warm the surface. It is well-known that IR radiation causes CO2 molecules to vibrate, but only at very specific wavelengths (wavelengths are the distances between peaks of each wave), and that wavelength is 15µm. (Fifteen µm means that each wavelength crests at a distance of 15 millionths of a meter.) As was discussed above, this vibration of the molecule causes it to heat and then radiate IR radiation back toward the atmosphere and the surface of the Earth. If the solar activity is taken to remain constant, more CO2 in the atmosphere will trap more of the OLR, and thus cause a net heating of the planet.
So what type of experiment could be performed to test this AGW hypothesis? If there were satellites in orbit monitoring the emission of OLR over time at the same location, then OLR could be measured in a very controlled manner. If, over time, the emission of OLR in the wavelengths that CO2 absorbs decreases over time, then that would prove the AGW hypothesis (i.e., that OLR is being absorbed by CO2 and heating the planet instead of being emitted from the atmosphere). But what if, over time (say, over thirty years), the emissions of OLR wavelengths that CO2 absorb remained constant? That would disprove the hypothesis and put the AGW argument to bed.
As luck would have it, that experiment has actually been performed! Three journal papers report the data from three monitoring satellites that have measured the OLR of 1997 and 2006 and compared those measurements to 1970, and they are located here, here, and here.

The peer review process needs to be reformed.
No more secret data.
No more secret software.
Everything must be be out in the open and available for all to see.
