Figure 5

Time series of normalized river runoff originating from glaciated headwaters in the Tien Shan mountain ranges during 1961–2014. Colored marker lines indicate the nine rivers shown in Fig. 1a. All data are normalized relative to the mean and standard deviation of the overlapping period (1980–2011). Trends for each river are calculated using the robust Theil–Sen estimator (see Methods). The black line is the average of two remote montane rivers: Shaliguilanke and Xiehela. Shading and dotted lines indicate 95% confidence intervals on trends in this time series. Detailed information for these nine rivers is listed in Supplementary Table S2.
