Changes in Annual Precipitation Averaged for 2091 to 2100

Changes in Annual Precipitation Averaged for 2091 to 2100: Using an "ensemble" of 18 global climate models and the moderate "A1B" emissions scenario, researchers at the NOAA Earth System Research Laboratory (ESRL) predict a reduction in precipitation across the Southwest by the end of the century.
