This comparative graph about the effects of Solar Irradiance (SI) upon Tropospheric Temperature (TT) versus Carbon Dioxide (CO2) upon TT clearly demonstrates that the observed Δ TT depends almost exclusively of the SI, instead of on the concentration of CO2 in the atmosphere.

The red shaded area in the graph indicates the deviation of the TT observed in nature with respect to the expected temperatures from the algorithm applied by the IPCC that was adopted for delineating the Kyoto Protocol (:: Δ TT - :: Δ [CO2]). The discrepancy between the real Δ TT is 1.124, which is a very high uncertainty that allows us to reject the hypothesis about the anthropogenic cause of the increase in the atmospheric CO2 and the Global Warming.

Something extremely important, evidenced by this graph, is that the CO2 concentration began to increase during the Maunder Minimum, perhaps by the great amount of atmospheric dust that obstructed the solar light until reaching the photosynthetic systems with an adequate intensity or a specific wavelength for the process. When the increase of CO2 started, there were neither automobiles nor human industries, and the world human population was very small (about 100 million persons in the world).
