The Science is settled? Proponents of Anthropogenic Global Warming and sceptics alike virtually all have one thing in common. They all claim that no one questions the basic science behind the "Greenhouse Effect". The commonly accepted position on both sides of the debate is that the science behind the "Greenhouse Effect" is well established 150 year old physics. This sounds all well and good until you remember that the "Greenhouse Effect" is still only a hypothesis. A scientific hypothesis is NOT established science. In fact in the field of science, you cannot be further away from established scientific fact than a hypothesis. The picture becomes even clearer when you consider the fact that the "Greenhouse Effect" hypothesis has remained a scientific hypothesis for more than 180 years, since Joeseph Forier first proposed it in the 1820's. The next character to attempt to wrap some meat around this hypothesis was John Tyndall when he was professor of physics at the Royal Institution of Great Britain in the 1850's.
In order to single out certain atmospheric gases and demonise them as the culprits responsible for atmospheric warming, it was necessary to attribute certain characteristics to the so called "Greenhouse Gases" with regard to radiant heat which would set them apart from the two most abundant atmospheric gases, Oxygen and Nitrogen. In his memoirs entitled "Contributions to Molecular Physics in the Domain of Radiant Heat", detailing a series of experiments conducted at the Royal Institution, Tyndall fallaciously states with regard to Oxygen and Nitrogen that they are both quote: "practically transparent to radiant heat." Thus laying the foundations of AGW fraud. This statement by John Tyndall is the origin of such claims as "the science is settled" and the "greenhouse effect is 150 year old established physics." In terms of radiant heat it is the only factor that would differentiate between the various atmospheric gases. After all, Oxygen and Nitrogen constitute 99% of the atmosphere. If these two gases are shown to absorb and re-emit infrared radiation, what would make so called "Greenhouse Gases" like CO2, such a threat to the environment at only 0.0385% of the atmosphere? So the basis for the "Greenhouse Effect" is that incoming and out going IR is not absorbed by Oxygen and Nitrogen which instead passes straight through these gases. According to this unsubstantiated hypothesis, only those gases which are termed "Greenhouse Gases" posses the capability to absorb and re-emit infrared radiation. The problem for the hypothesis of the "Greenhouse Effect" and of course AGW itself is that the basic premise on which the hypothesis is based is false. Firstly, Oxygen and Nitrogen both have higher specific heat capacities than CO2. For verification see here: Specific heat capacity of Gases Secondly and above all, Oxygen and Nitrogen, of course do indeed absorb infrared radiation: Infrared absorption bands for OXYGEN A close-up of an infrared absorption band for NITROGEN As can be seen in figure 1 below, Nitrogen is clearly absorbing infrared radiation at between 3.8 and 5 micrometers. If we then examine this wavelength on the electromagnetic spectrum chart in figure 2, it is clear that this wavelength falls inside the infrared portion of the electromagnetic spectrum. Figure 1
Figure 2
The infrared absorption bands for Nitrogen between approximately 1992 and 2626 are confirmed by this absorption spectrum reference table for gas molecules courtesy of the Hitran database. Figure 3
It is a similar case for Oxygen which also has many absorption bands within the range of infrared radiation.

The evidence I have presented here conclusivly shows that Oxygen and Nitrogen which constitute 99% of the Earths atmosphere, as one would expect, do in-fact absorb infrared radiation. The claim that these two gases are transparent to IR is completely fallacious. Which goes along way to explain why the "Greenhouse Effect" hypothesis is one of the longest standing unsubstantiated hypothesis in the history of science. The so called "Greenhouse Effect" will always remain an hypothesis for the simple reason that it is based on pseudo science.
