As this chart depicts, atmospheric CO2 growth has been on a fast-track growth curve. CO2 levels have been accelerating up since 1960 - true relentless growth.
The dogmatic and conventional global warming hypothesis claims that this type of CO2 level growth will cause a dangerous increase of both atmospheric and surface temperatures, thus increasing atmospheric water vapor - i.e., humidity - leading to a positive feedback loop of non-stoppable accelerating global warming.
Clearly, as this chart of empirical evidence reveals, that has not happened. Atmospheric humidity has actually declined, while the atmosphere and ocean temperatures accelerate, decelerate and often develop cooling phases.
Unlike the monotonous, steady state, fast CO2 growth, the major climate measurements are highly variable, obviously unlinked to the CO2 input from humans.
However, per the evidence and the newest research, a case can be made that the non-acceleration and variability of global temperatures for the last 15+ years may have more to do with the 11-year cycles of sunspot activity not being as strong during recent solar peaks than the relentless CO2 growth.
