OUR CHANGING PLANET The U.S. Climate Change Science Program for Fiscal Year 2009 A Report by the Climate Change Science Program and The Subcommittee on Global Change Research A Supplement to the President's Fiscal Year 2009 Budget

Observed trends in groundwater input (denoted by left side of symbol) and annual flow (denoted by right side of symbol) at Yukon River Basin streamflow stations. Circles and squares indicate flow records longer and shorter than 35 years, respectively. Symbol color scheme indicates statistical significance of Mann-Kendall trend analysis: red = very highly significant (P<0.01) increasing trend, orange = highly significant (0.01<P<0.05) increasing trend, yellow = moderately significant (0.05<P<0.1) increasing trend, light blue = moderately significant (0.05<P<0.1) decreasing trend.
