Republicans never acknowledge that climate models are among the most formidable and exacting challenges scientists undertake. Then to make matters worse Republicans are consistently misrepresenting not only how climate models are used, but also doing their best to characterize them as failures, when they most certainly are not failures!
For the details on the General Circulation Model success story I’m going to hand it over to Coby Beck with the introduction to his November 20, 2006 Grist article. After that I list significant models that have been correct. Which is followed by links to and exerts from various informative articles.

‘Climate models are unproven’ – Actually, GCM’s have many confirmed successes under their belts
By Coby Beck on Nov 20, 2006
… In 1988, James Hansen of NASA GISS fame predicted [PDF] that temperature would climb over the next 12 years, with a possible brief episode of cooling in the event of a large volcanic eruption. He made this prediction in a landmark paper and before a Senate hearing, which marked the official “coming out” to the general public of anthropogenic global warming.
Twelve years later, he was proven remarkably correct, requiring adjustment only for the timing difference between the simulated future volcanic eruption and the actual eruption of Mount Pinatubo.
