I don't think there is a short and easy answer other than that most models overstate the certainty of their conclusions.
I'm not afraid of a long and hard answer, if you have one.
Just take a look at temperature plots for the last 50 years or so and check what your eyes tell you :-)
Looking at the official data released by NASA, there is no warming hiatus.
The long and hard answer is about a book's length in size and might well be more.
As to data, there are several "official" series, IIRC from NASA, from NOAA, and from the Hadley Centre. See e.g. this. Data is freely available, so you can plot your own.
However I don't know why there is controversy over the existence of hiatus if even the IPCC 2013 report accepts it as existing and spends a few pages (Ch. 9) discussing it.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
