Quote from the article: "A year that was supposed to mark a turning point both for the US and global economy is rapidly turning into the recovery that wasn't. At a time when things were supposed to be getting better they are instead turning worse: Commodity prices are eating into consumer spending, historically low interest rates haven't done a thing to help housing, and, most worrisome, the job market rebound has been stopped in its tracks. Is it too early, then, to talk about a double dip? Probably."
I don't think we can really call it a "double dip" when most signs indicate that there has been no recovery.
