This presented WUWT post offers information of great significance! It concerns a factor of actual global warming that is real, has substance and yet is completely ignored by the IPCC “scientists” and associates, who have to include a “fiddle factor” to get their computer-modeled predictions anywhere near to the actual, real ‘global warming’ that they claim is a major destroyer of our civilization.
They abandoned their earlier “global warming” term, because the actual warming wasn’t following their computed predictions. They then coined “climate change” so that they could falsely blame all types of weather and other factors as being causes of serious climatic changes.
Causes clearly shown by scientific, WUWT publications, to be scientifically invalid.

Diverting slightly, there is no substantiated evidence that increases in our approximately 400ppm, (0.4%), atmospheric CO2 level, by say 10% (of that miniscule level) would be a major, global, atmospheric weather influence.

Coming back to the point: Clouds, atmospheric water vapour in general, are not included in the IPCC vocabulary/science as a greenhouse gas at all, let alone of interest. Here, courtesy WUWT, we have something of real interest. Something scientific!!
