Kevin E. Trenberth quotes:

...Was it because a lot of the heat went into melting Arctic sea ice or parts of Greenland and Antarctica, and other glaciers? Was it because the heat was buried in the ocean and sequestered, perhaps well below the surface?...Perhaps all of these things are going on?

Well, I have my own article on where the heck is global warming?...The fact is that we can't account for the lack of warming at the moment and it is a travesty that we can't.
