New paper finds IPCC climate models unable to reproduce solar radiation at Earth’s surface

A new paper published in the Journal of Geophysical Research – Atmospheres finds the latest generation of IPCC climate models were unable to reproduce the global dimming of sunshine from the ~ 1950s-1980s, followed by global brightening of sunshine during the 1990′s.

These global dimming and brightening periods explain the observed changes in global temperature over the past 50-60 years far better than the slow steady rise in CO2 levels.

The authors find the models underestimated dimming by 80-85% in comparison to observations, underestimated brightening in China and Japan as well, and that ”no individual model performs particularly well for all four regions” studied.
