A graph that disproves AGW

From The Inconvenient Skeptic comes a graph that disproves AGW, showing satellite observations which prove that for each 1C increase in Northern Hemisphere temperature, outgoing longwave radiation increases by 2.2 W/m2. According to the IPCC, a doubling of CO2 levels will "trap" 3.7 W/m2 in the troposphere to cause 3C warming at the Earth's surface. However, as shown by this graph, a 3C warming would increase outgoing radiation to space by 3*2.2 = 6.6 W/m2, far more than the heat claimed to be "trapped" by doubled CO2 of 3.7 W/m2. As stated by The Inconvenient Skeptic, "There is simply no physical method by which CO2 is capable of overcoming this barrier.  There never has been and there never will be. This is why global warming by means of CO2 level is impossible and always will be impossible."


From The Inconvenient Skeptic:
Northern Hemisphere (NH) Outgoing Longwave Radiation (OLR) as a function of NH temperature 
The direct dependence is a 4th order one, but even a simple linear regression gives an R^2 of 0.96.  Every 1 °C change in temperature results in a 2.2 W/m^2 increase in NH OLR.  There is simply no physical method by which CO2 is capable of overcoming this barrier.  There never has been and there never will be.  This is why global warming by means of CO2 level is impossible and always will be impossible.
