That view is pretty well supported.  There are a lot of different cycles going "negative" right now, including, apparently, the solar cycle.  Gonna be an interesting few years in here, I think.  It's notable, that the last time the Oceanic and atmospheric cycles were in this phase, the sun was in a very active cycle.  If the Sun has gone into a "minimum" type cycle, which it currently appears it may, then the combination could lead to much cooler temperatures than we're used to.

 Here's a paper I found that's dealing with it.
