I have heard it's because of el Nino:

(but I'm not a meteorologist just a sailor).

I doubt it's a tipping point. I suspect it's just the increased energy 
in the system (for whatever reasons) means that the formally-chaotic 
weather systems are getting pushed towards bifurcation points and so the 
erratic-ness(?) of the weather is increasing.

But what do I know. Nada :)
