This is rather remarkable.
“The claim that man-released CO2 stays in the atmosphere for hundreds of years was necessary for the alarmist case. It was required to justify the notion of “commitment” to the temperature rise that might happen few hundred years in the future according to the alarmist computer models. It allowed to exaggerate future CO2 concentrations, and to demand premature action (a typical high pressure selling tactic – act now, regret later). And IPCC pulled out all the stops to justify such claims. It tried to create the impression that CO2 is something like a demon from the underworld: ignoring the laws of physics, harmful and dangerous, and difficult to exorcize.” click here
