Forecast stream runoff changes. This map shows forecast stream runoff patterns for the end of the century. Changing precipitation and temperatures are predicted to reduce stream runoff in some regions and increase it in other regions. The southwestern United States is expected to experience stream reductions of up to 40% by 2100.
