Computer model predictions from a virtual simulated climate are functionally worthless. For a multitude of reasons, climate simulation models will continue to fail at the task of predicting usable/actionable global climate forecasts. (click on images to enlarge)
Update: More proof that IPCC climate models don't work as claimed. Another update: "This paper reinforces two issues that have repeatedly been made on my weblog: The multi-decadal IPCC global climate models, which have predicted more-or-less perpetual drought in the southwestern United States, are failing in their regional prediction."
Yet, climate science and policy has been bedeviled by the extreme over-reliance on these virtually simulated climate projections. Like a crack addiction, the elites have become addicted to the faulty prediction output of these models, regardless of what the empirical climate data and observations say otherwise. The scientists, politicians, pundits and celebrities of the "elite" class have become so blinded by the "rush" of virtual climate global warming predictions that rationale and cost-effective solutions became literally impossible to civilly discuss/debate, let alone implement.
Unfortunately, the addiction to computer model forecasts is not restricted to climate science. The elites on "model-crack" exist throughout government, industry and the mainstream press, and they continue to be amazed at the gross failures of computer predictions, even those failures in the realm of simplicity (like the housing market) in comparison to the chaotic, complex computer models of the climate.
