So it shouldn't be used to rule out whether or not a particular observed value is consistent with model expectations, but does give you some guidance as to just how far from the average model expectation the current trend lies (a cherry picker is not usually worried about the finer details of the former, but, instead, the coarser picture presented by the latter).
Current GCM models may have realistic - seeming weather patterns, but are totally incapable of producing phenomena that look like the Holocene (Little Ice Age, Medieval Warm Period, Roman Warm Period, Holocene Optimum, the steady decline of temperature on average over the last 3,000 years, etc.) The Climate Science community has, instead, taken the path of trying to claim that these swings didn't occur (Michael Mann's «Hockey Stick», etc.) This does not give me a lot of confidence in the rest of their «science».

None of these could have been caused by an increase in atmospheric CO2, Model projections of warming during recent decades have greatly exceeded what has been observed, The modelling community has openly acknowledged that the ability of existing models to simulate past climates is due to numerous arbitrary tuning adjustments, Observations show no statistically valid trends in flooding or drought, and no meaningful acceleration whatsoever of pre-existing long term sea level rise (about 6 inches per century) worldwide, Current carbon dioxide levels, around 400 parts per million are still very small compared to the averages over geological history, when thousands of parts per million prevailed, and when life flourished on land and in the oceans.
The models do reproduce the 20th century, and even the last 1000 years globally averaged reasonably well, observational data of forcing factors permitting, and they do this with the same physics that produce 2xCO2 sensitivity as 2.9 oC There is another essential factor in looking at current T rise vs CO2 forcing and that is the global dimming phenomenon.
