I didn't see that, but I put it right up there with the "California is going to fall into the ocean" thing everyone was yelling about a decade or two ago. It's true enough, but everyone always fails to mention it will take millions of years.
As PHinker pointed out, people like to make themselves feel more significant by manifesting ideas that events of their lifetimes' are the critical turning-point. "Scientists" like to make radical predictions in order to get more funding. Example: Just look at the "Pluto isn't a planet anymore" thing, to boost media attention. Not long before then, they were thinking about labeling one of Pluto's moons as a planet. They're just fishing for an angle to boost attention and financing. Sad really. They've only managed to discredit themselves, in my eyes.
Anyhow, as an (ex)pilot, I can tell you that figuring for magnetic declination is a daily practice when flight planning. It doesn't change all that much. Perhaps it will invert some day, but don't expect it to happen in your lifetime. (or your children's, or your grandchildren's, and so on)
The sky is falling, the sky is falling!!!!! :~\ or not.
