Billions upon billions have been poured into climate research and the infamous climate computer models - after those untold billions, the newest CMIP5 climate models are still unable to predict global temperatures with any accuracy

Complex, mind-boggling multivariate models more often than not produce a huge surplus of garbage output (see chart) that confuses both policymakers and the public, resulting in poor policy choices and failed implementation strategies and tactics.
Combine that typical outcome with the well known phenomenon of garbage in, garbage out (GIGO) that is inherent to all computer simultations and the likely result is a manifesto for a big fail.
Some recent public examples of computer complex simulation fiascoes include: computer models causing a 2-year delay in finding the black box from Air France Flight 474; the hysterical computer projections about potential bird flu deaths; the abysmal computer prediction regarding Obama's "stimulus" affect on unemployment; and, of course, the Federal Reserve's 2007 econometric model prediction that completely missed the soon-to-be 'Great Recession' - and don't forget the recent gargantuan fail of these type of "expert" computer models.
So it should come as no surprise that computer attempts at predicting outcomes for the incredibly complex, chaotic world's climate are bound to fail.
To that point, it has been recently observed that past climate model forecasts have been spectacular failures due to bad assumptions and a fanatical blind loyalty to a very weak (lame?) AGW hypothesis. And as the above chart indicates, the newest CMIP5 climate simulations appear to be not much better.
Thus, it is a safe bet that proposing trillion-dollar climate solutions based on the outputs of these new models will prove to be another common sense (no computer needed) predictable disaster. However, that will again be in hindsight for the political elites and mainstream journalists.
