From known thermal conductivities (Table 5), isochoric heat capacities, and mass densities the isochoric thermal diffusivities of the components of the air are determined (Table 6). This allows to estimate the change of the effective thermal conductivity of the air in dependence of a doubling of the CO 2 concentration, expected to happen within the next 300 years (Table 7). It is obvious that a doubling of the concentration of the trace gas CO 2 , whose thermal conductivity is approximately one half than that of nitrogen and oxygen, does change the thermal conductivity at the most by 0, 03 % and the isochoric thermal diffusivity at the most by 0.07 %. These numbers lie within the range of the measuring inaccuracy and other uncertainties such as rounding errors and therefore have no significance at all.
