    Pilot project helps USACE evaluate changing climate across Southwest

    During the next century, the Southwestern United States is anticipated to warm at a rate second only to Alaska, driving up evaporation rates, driving down soil moisture, and resulting in reduced stream flow, increased erosion/sedimentation, and increased wildfire severity and forest loss. With drought conditions anticipated to occur in 80 percent of the years between now and 2100, water is anticipated to be the defining issue of this century.
