These maps show baseline (1961-1990) average total precipitation and projected change in precipitation for the decades spanning 2010-2039, 2040-2069, and 2070-2099. Precipitation is expressed in both millimeters (mm) and inches (in); projected change in precipitation is expressed as percent of baseline. Baseline results for 1961-1990 are derived from Climate Research Unit (CRU) TS 3.1.01 data and maps for future time periods are based on a composite of projections from five GCMs (CCSM4, GFDL-CM3, GISS-E2-R, IPSL-CM5A-LR, and MRI-CGCM3) under the AR5-RCP 8.5.
