Decline in terrestrial water storage (IMAGE) Penn State Caption Time series of reconstructed terrestrial water storage anomalies (TWSA) and TWSA estimated from GRACE JPL-M over the (a) Amu Darya and (b) Indus basins. The red line shows GRACE observations, whereas the blue line shows the ensemble mean of reconstructed TWSA from nine GCMs (Table S2). Shadows represent uncertainty range of ±1 standard deviation among outputs from different GCMs. Credit Courtesy: Penn State, Tsinghua University Usage Restrictions Educational use only License Original content Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to EurekAlert! by contributing institutions or for the use of any information through the EurekAlert system.
