GR: These results confirm earlier predictions. The projected changes are milder if we cut greenhouse gas emissions now, but they still occur. Interesting that while drought continues in the Southwest, the Arizona monsoon will intensify.
“The twenty-first century may bring the United States more of the weather it’s already got, whether wet or dry. The U.S. National Climate Assessment, issued in May 2014, examined multiple model projections of seasonal precipitation over the rest of this century. In general, precipitation is projected to increase in the northernmost parts of the country, and decrease in the southwestern United States.
“These maps show projected seasonal precipitation changes for the final decades of this century (2071-2099) compared to the end of the last century (1970-1999) depending on two possible scenarios for greenhouse gas emissions. One scenario assumes that greenhouse gas emissions peak sometime between 2010 and 2020 and rapidly decline afterwards. The other scenario assumes that greenhouse gas emissions continue increasing throughout the 21st century.”
