Dr. Pettersson finds "the IPCC extremely (about tenfold) underestimated both the speed of the final location for the natural disposal of atmospheric carbon dioxide" by natural sinks. The assumption of the "IPCC Bern model that 22% of atmospheric carbon dioxide surplus can never be removed from the air seems quite amateurish considering that the present empirical observations (Fig. 1) confirms that at least 95% of the bomb test excess of 14C-carbon dioxide has been removed "already" after 50 years."
"Paper 2 shows the bomb curve estimated value of the CO2 relaxation time (14 years) and concludes that the IPCC-backed climate models overestimate future anthropogenic contribution to atmospheric carbon dioxide concentration by a factor of 3-15 depending on the emissions scenario and the considered time period. This means that emissions of fossil carbon dioxide can not be expected to lead to a politically unacceptable global warming (two degree target), even according to the IPCC's worst case discharge scenarios, the longest present experimentally determined estimate of the relaxation time, and the alarmist climate models' own estimates of the greenhouse effect strength."
"The IPCC has been scientifically untenable reasons turned a blind eye to the present very extensive and entirely consistent experimental results concerning CO2 relaxation and preferred to base their assessments on a mathematical model that lacks empirical support, and even contrary to the observations made."
