Anthropogenic global warming (AGW) is merely conceptual, not quantifiable

“According to one of the most frequently referenced papers advancing the position that CO2 concentration changes (and downward longwave radiation perturbations) drive surface temperature changes, Feldman et al. (2015)concluded there was a modest 0.2 W/m² forcing associated with CO2 rising by 22 ppm per decade. Again, that’s a total CO2 influence of 0.2 W/m² over ten years. In contrast, analyses from several new papers indicate the uncertainty and error values in downwelling (and outgoing) longwave radiation in cloudless environments are more than 100 times larger than 0.2 W/m².” click here
