Since all of the IPCC's models «project» the «likelihood» of a steady warming over this period, all of them must be wrong, and we can expect similar failures for all the other «projections».»

The primary model for attributing the observed bulge in atmospheric CO2 to human activity was invalid, but IPCC concealed its failure.

As far as I am concerned, GCMs are «good enough» at projecting scenarios, and all this «but regional models» amounts to a smokescreen to obfuscate rpielke's failure to explicitely commit his agreement disagreement regarding the IPCC's main attribution statement.

No matter what political committees try to absolve corruption of climate science of the Climatic Research Unit (CRU) and the Intergovernmental Panel on Climate Change (IPCC), they can not hide the complete failure of the computer models to make a single accurate prediction.

Many other examples of this type of test can be found in chapter 8 (Climate Models and Their Evaluation) of IPCC / AR4, which assesses both model successes AND model failures.

The failure of the IPCC machine is especially evident in the use of «models» to justify claims, so it might be worthwhile to just look at modeling and science.

In addition, the scientists determined that the climate models, favored by the IPCC and other non-empirical based scientists, are unable to faithfully mimic the ancient past AMO variability due to geographic differences (location differences)- a major climate modeling failure.

In contrast, the IPCC climate models predicted a significant cooling trend for the Tropics for those 83 months - an abysmal failure, represented by a 7 degree trend difference between reality and prediction.

Prof. Judith Curry (another IPCC author) also believes that the failure of the climate models to predict the «pause» in global warming indicates that the IPCC has substantially underestimated the role of natural variability in recent climate change, e.g., see here, here, here or here.

While the IPCC's associated climate «experts» are going through their own set of mental gyrations to explain the abysmal climate model and AGW hypothesis performances, two scientists explain how this failure was produced - article number one and article number two.

The most obvious explanation for the striking failure of most climate models to account for the pause in warming over the past decade is that the value of ∆ T2 is much smaller than the IPCC value.

I came to the conclusion that one of the major failures of the models & IPCC climate projections is to think that the «inside» part of the atmosphere is a constant heat transfer with no influence on the climate.

What matters is the IPCC changed the graphs for the same reason they changed the language regarding the failure of the models to predict the pause.

Such solecisms throughout the IPCC's assessment reports (including the insertion, after the scientists had completed their final draft, of a table in which four decimal points had been right - shifted so as to multiply tenfold the observed contribution of ice - sheets and glaciers to sea - level rise), combined with a heavy reliance upon computer models unskilled even in short - term projection, with initial values of key variables unmeasurable and unknown, with advancement of multiple, untestable, non-Popper-falsifiable theories, with a quantitative assignment of unduly high statistical confidence levels to non-quantitative statements that are ineluctably subject to very large uncertainties, and, above all, with the now - prolonged failure of TS to rise as predicted (Figures 1, 2), raise questions about the reliability and hence policy - relevance of the IPCC's central projections.

The present analysis suggests that the failure of the IPCC's models to predict this and many other climatic phenomena arises from defects in its evaluation of the three factors whose product is climate sensitivity:
