>I mean I guess its possible that the drought and increased rainfall are caused by the same thing. From the abstract: "This uncertainty is related to several factors, including relatively large internal climate variability, model shortcomings, and because CA lies within a transition zone, where mid-latitude regions are expected to become wetter and subtropical regions drier." So yes, it looks like CA is in for both. Increased aridity in the south, with more extreme precipitation hitting the north.
