内流（水文内陆）流域在空间上与干旱/半干旱气候一致。由于降水量有限，但蒸发潜力很大，这些地区的水储存很容易受到微妙的通量扰动的影响，而全球变暖和人类活动又加剧了这种扰动。越来越多的区域证据表明，可能是最近的内陆水储存净下降，但这仍然是在全球范围内量化。通过整合卫星观测和水文模型，我们发现，在2002-2016年期间，全球内陆系统经历了约106.3 Gt/年的广泛水损失，这归因于地表水，土壤水分和地下水的可比损失。这种十年的下降与外流盆地的水储存波动不同，似乎对厄尔尼诺-南方涛动驱动的气候变率不太敏感，这意味着可能对长期气候条件和人类水管理做出反应。在质量守恒的水圈中，这种内流水的流失不仅加剧了当地的水压力，而且还使外流盆地的水过剩，导致潜在的海平面上升，与近一半的陆地冰川退缩（不包括格陵兰和南极洲）的贡献相匹配。考虑到这些双重影响，我们建议有必要长期监测全球内流系统中的水储存变化，并将其净贡献纳入未来的海平面预算。
Endorheic (hydrologically landlocked) basins spatially concur with arid/semi-arid climates. Given limited precipitation but high potential evaporation, their water storage is vulnerable to subtle flux perturbations, which are exacerbated by global warming and human activities. Increasing regional evidence suggests a probably recent net decline in endorheic water storage, but this remains unquantified at a global scale. By integrating satellite observations and hydrological modelling, we reveal that during 2002–2016 the global endorheic system experienced a widespread water loss of about 106.3 Gt yr−1, attributed to comparable losses in surface water, soil moisture and groundwater. This decadal decline, disparate from water storage fluctuations in exorheic basins, appears less sensitive to El Niño–Southern Oscillation-driven climate variability, which implies a possible response to longer-term climate conditions and human water management. In the mass-conserved hydrosphere, such an endorheic water loss not only exacerbates local water stress, but also imposes excess water on exorheic basins, leading to a potential sea level rise that matches the contribution of nearly half of the land glacier retreat (excluding Greenland and Antarctica). Given these dual ramifications, we suggest the necessity for long-term monitoring of water storage variation in the global endorheic system and the inclusion of its net contribution to future sea level budgeting.
