No doubt a warmer atmosphere would lead to increased precipitation, but that doesn't necessarily correlate directly to an increase in extreme weather events. In fact, contrary to media hype, there doesn't actually seem to have been any increase in hurricanes, tornadoes, etc., and we're agreed that the present weather is evidence of nothing. I highly recommend Bjørn Lomborg's Cool It for a thoroughly lucid analysis.
As for the North Atlantic Conveyor, the IPCC's 2007 report is pretty unambiguous: "none of the current models simulates an abrupt reduction or shut-down." (Climate Change 2007: WGI: The Physical Science Basis, Question 10.2, emphasis added.) The Day After Tomorrow is fiction, whatever Al Gore might think.
