Changes in river discharge due to climate change are highly uncertain, and a recent study used a global streamflow dataset to assess whether such trends are detectable. Streamflow changes occurred more often in basins impacted by human disturbances than in pristine ones, and there was no clear signal from climate change alone.

人类、气候和水流

气候变化引起的河流流量变化具有高度不确定性，最近的一项研究使用全球流量数据集来评估是否可以检测到这种趋势。与原始流域相比，受人为干扰影响的流域更常发生流量变化，仅气候变化没有明确的信号。
