Abstract. In the face of climate change and increasing anthropogenic pressures, a reliable water balance is crucial for understanding drivers level fluctuations in large lakes. However, poorly gauged hydrosystems such as Lake Titicaca, most components are not measured directly. Previous estimates this lake have relied on scaling factors to close balance, which introduces additional uncertainty. This study presents an integrated modeling framework based conceptual models quantify natural hydrological processes net irrigation consumption. It was implemented Water Evaluation Planning System (WEAP) platform at daily time step period 1982–2016, considering following terms balance: upstream inflows, direct precipitation evaporation over lake, downstream outflows. To estimate we evaluated impact snow ice withdrawals predicted streamflow levels. We also role heat storage from lake. The results showed that proposed makes it possible simulate levels ranging 3808 3812 m a.s.l. with good accuracy (RMSE = 0.32 d−1) wide range long-term hydroclimatic conditions. estimated Titicaca shows inflows account 56 % (958 mm yr−1) 44 (744 total while 93 (1616 outflows due remaining 7 (121 closure has error −15 yr−1 without applying factors. Snow processes, together withdrawals, had minimal variations level. Thus, primarily driven by high rates.

Here we show that human-caused warming has caused Northern Hemisphere-scale March over 1981–2020 period. Using an ensemble reconstructions, identify robust trends 82 out 169 major Hemisphere river basins, 31 which can confidently attribute human influence.

Such nonlinearity explains lack widespread so far augurs much sharper most populous basins. Together, our results emphasize their consequences are attributable—even absent clear individual products—and will accelerate homogenize with near-term warming, posing resources absence substantial mitigation.

Abstract The availability of surface water in global drylands is essential for both human society and ecosystems. However, the long-term drivers change storage, particularly those related to anthropogenic activities, remain unclear. Here we use multi-mission remote sensing data construct monthly time series storage changes from 1985 2020 105,400 lakes reservoirs drylands. An increase 2.20 km 3 per year found primarily due construction new reservoirs. For old (constructed before 1983), conversely, trend minor when aggregated globally, but they dominate trends 91% individual dryland basins. Further analysis reveals that these bodies are linked factors—including human-induced warming water-management practices—rather than precipitation changes, as previously thought. These findings reveal a decoupling drylands, raising concerns about societal ecosystem sustainability.
