The following figures are from the National Center for Atmospheric Research (NCAR) CSM Business-as-Usual and Stabilization scenarios.  Temperature is mean screen temperature and is mapped as a delta.  Precipitation is mapped as percent difference, which is  (future-modern)/modernx100.  The differences between the two scenarios are plotted similarly.  The time series, which have been filtered to eliminate less than 4 year variations, show that the large precipitation increase in the southwest is a factor of decadal variance, and not of any larger trend of increasing precipitation in that region.  Maps were created by Aiguo Dai at NCAR.
