I was asked this question resently. Well, I think the weather is behaving just like it supposed to. Apparently we are on our way to a cooling cycle. Those are preceeded by a warmer periode. The warmer weather melts the ice on polarcaps, more water is circulating, weather patterns change.

On top of that the melting of the ice caps mean a different weight distribution on the continental plates, which leads to earthquakes because of new adjustments – which leads to volcanic activity as when you shake a Coke.

Nothing mysterious about all of this. A bit of a nuisance perhaps, but nothing mysterious.
