The climate models sensitivity to carbon is overrated

Comparison of reconstructed global land and sea temperature (for example GISS [1]) and anthropogenic carbon dioxide time histories (for example CDIAC [2]) over the last century show a very different sensitivity of temperatures to anthropogenic carbon dioxide emissions than what is claimed by Otto, A., Otto, F.E.L., Boucher, O., Church, J., Hegerl, G., Forster, P.M., Gillett, N.P., (…), Allen, M.R. in their paper Energy budget constraints on climate response, Nature Geoscience 2013 6 (6):415-416.
The reason why climate models are failing so badly so quickly is not because of the “variability” in the climate, but because of the overrated effect of anthropogenic carbon dioxide emissions and neglected natural oscillations.
Figure 1 presents the non-dimensional global temperatures as reconstructed by GISS and the non-dimensional carbon emission as reconstructed by CDIAC vs. time 1910 to present. While carbon emissions are growing almost exponentially, the temperature has a much more complex behaviour where two natural oscillations of about 60 years are clearly superimposed to a longer term trend that may be natural and/or carbon driven. The upwards phases 1910 to 1940 and 1970 to 2000 are followed by the downward phases 1940 to 1970 and 2000 to the present (and very likely to 2030). As pointed out in the recent works [3-7], the climate sensitivity is overrated when correlating the temperature and carbon dioxide emission behaviour over the time window 1970 to 2000.













The interplay results in individual differences in knowledge and skills, and in this way differences in intelligence arise. The role of education, culture, and society is crucial in this process; they enable genetic effects to arise. The larger the environmental influences, the larger the genetic effects.

The report is a well documented and thoroughly researched analysis of the hypothesis put forth by the Intergovernmental Panel on Climate Change (IPCC) that recent increases in atmospheric CO2 caused by human emissions from fossil fuel combustion is causing, or will cause, dangerous global warming and climate change. Such warming has been observed in the late twentieth century as atmospheric CO2 was measured to increase. According to the IPCC paradigm increases in atmospheric CO2 precede, and then cause, parallel increases in temperature.
