IPCC Climate Model Projections Diverging from Reality

The humorous facet of this affair is that the 2007 IPCC GCM model did very well at "predicting" the climate prior to 2007! It is only after the model was forced to project into the future (rather than the past) that its projections began to swing widely away from actual observed temperatures.

Sunspots influence low-level clouds which then influence average global temperature. A licensed engineer’s assessment of what has been and is going on is available. A wider lower solar cycle can have the same influence on climate as a narrow high one. The sunspot time-integral exploits this to, with ocean cycles, calculate average global temperatures since 1895 with 88% accuracy as demonstrated in detail in the pdf made public 11/24/11 at http://climaterealists.com/index.php?tid=145&linkbox=true . The derived simple equation that does this also accurately (std dev less than 0.1C) predicts temperatures since 1990. Change to the amount of atmospheric CO2 has no significant influence.
