"Former NASA scientist Dr. Roy Spencer says that climate models used by government agencies to create policies “have failed miserably.” Spencer analyzed 90 climate models against surface temperature and satellite temperature data, and found that more than 95 percent of the models “have over-forecast the warming trend since 1979, whether we use their own surface temperature dataset (HadCRUT4), or our satellite dataset of lower tropospheric temperatures (UAH).”
“I am growing weary of the variety of emotional, misleading, and policy-useless statements like ‘most warming since the 1950s is human caused’ or ‘97% of climate scientists agree humans are contributing to warming’, neither of which leads to the conclusion we need to substantially increase energy prices and freeze and starve more poor people to death for the greater good. Yet, that is the direction we are heading,” Spencer wrote on his blog."
Climate scientists have been baffled by the 17-year pause in global warming. At least eight explanations have been offered to explain the lapse in warming, including declining solar activity and natural climate cycles.
Some scientists have even argued that increased coal use in China has caused the planet to cool slightly. But there does not seem to be any solid agreement on what caused global surface temperatures to stop rising.
The latest explanation from climate scientists is that Pacific trade winds have caused the planet to stop warming. Stronger winds in the last two decades may have forced warmer water deeper while bringing cooler water to the surface.
“The net effect of these anomalous winds is a cooling in the 2012 global average surface air temperature of 0.1–0.2 degree Celsius, which can account for much of the hiatus in surface warming observed since 2001,” wrote Australian researcher led by Matthew England of the University of New South Wales.
“This hiatus could persist for much of the present decade if the tradewind trends continue; however rapid warming is expected to resume once the anomalous wind trends abate,” the Aussie scientists added. “Volcanoes and changes in solar radiation can also drive cooler decades against the backdrop of ongoing warming.”
Note that the old argument that the models won't show anything less than 15years, or was it 25years, or maybe 50years... is not the case. The models plot points every year, and use that data to kick off the next year's data. So if a year's data (or 17 year's data) is off, then their entire future projection will fail. The errors are cumulative.
Yes, there is some warming; but they don't know everything they think they know - or want us to think they know - or else their annual calculations would not be that far off.
I think someone, not me, should graph their excuses for failure. A deterministic science would have folded long ago under such errors. AGW is not a deterministic science, because it cannot make valid deductions based on existing global/universal physical principles. In actuality it appears to be another abductive failure.

I've made this point before regarding models:
"There's an old saying in programming that goes, "Garbage in, garbage out." In other words, if the assumptions and data you put into the models are faulty, then the results will be worthless. If the climate models that show a dire impact because of global warming aren't reliable -- and they're not -- then the long term projections they make are meaningless."
5 Scientific Reasons That Global Warming Isn't Happening

It's even worse when the calculations are wrong on top of the assumptions being wrong. You can see that in the data, above; the calculations are based on moving the initial conditions for a given annual calculation to the prior year's number. And you can see that the range of variation between models is very high and diverging. The 17 year "anomoly" (ocean turnover due to high winds) is nowhere accounted for in any of the calculations. And I'd bet that the dip between 1990 and 1995 was added to models ex post facto.
