By reconstructing the history of water impoundment in the world's artificial reservoirs, we show that a total of approximately 10,800 cubic kilometers of water has been impounded on land to date, reducing the magnitude of global sea level (GSL) rise by -30.0 millimeters, at an average rate of -0.55 millimeters per year during the past half century. This demands a considerably larger contribution to GSL rise from other (natural and anthropogenic) causes than otherwise required. The reconstructed GSL history, accounting for the impact of reservoirs by adding back the impounded water volume, shows an essentially constant rate of rise at +2.46 millimeters per year over at least the past 80 years. This value is contrary to the conventional view of apparently variable GSL rise, which is based on face values of observation.
通过重建世界人工水库的蓄水历史，我们发现迄今为止陆地共蓄水约10800立方千米，使全球海平面（GSL）上升幅度减少了30.0毫米，在过去半个世纪里平均每年减少0.55毫米。这意味着其他（自然和人为）因素对全球海平面上升的贡献比原本所需的要大得多。通过将蓄水量加回来以考虑水库影响而重建的全球海平面历史表明，至少在过去80年里，全球海平面上升速度基本恒定，为每年2.46毫米。这一数值与基于观测表面值的全球海平面上升明显变化的传统观点相反。
