Read here. The IPCC's Susan Solomon, and associates, recently published a peer reviewed study that clearly shows how bad climate models really are.
It is widely accepted that many atmospheric aerosols will act as a global cooling influence. There are background aerosols and those from volcanic eruptions that provide a cooling effect. Yet the climate model research produced by Solomon has aerosols causing a warming increase. (click on image to enlarge)
As the Solomon et al. research shows, as represented by the adjacent graph, the IPCC-type of climate models have aerosols increasing the warming trend instead of producing a cooling effect. In essence, the models contradict everything that IPCC global warming alarmists believe and claim.
"So instead of identifying why there has been less global warming over the past 10-15 years than climate models have projected, Solomon et al. have found that climate models have missed the mark even further—for had they properly included the effect of volcanoes and background stratospheric aerosols, they would have projected even a greater rate of warming than they already do. And since observations show that there has been relatively little, if any, warming over this same time period, the results from Solomon et al. means that climate models are doing worse than even the model lovers have realized."
