Well, that's awkward.

No statistically significant warming for 17+ years:

It is better to focus on the ever-widening discrepancy between predicted and observed warming rates. The IPCC’s forthcoming Fifth Assessment Report backcasts the interval of 34 models’ global warming projections to 2005, since when the world should have been warming at a rate equivalent to 2.33 Cº/century. Instead, it has been cooling at a rate equivalent to a statistically-insignificant 0.87 Cº/century:

The variance between prediction and observation over the 100 months from January 2005 to April 2013 is thus equivalent to 3.2 Cº/century.//

Also, here is the chart that explains why "warmists" can claim that three of the hottest years in the last 50 have occurred in the last 17 years, i.e., those hot years were followed by "cold" winters and cooler years, which is to say that on average there was no increase in global warmth.
