Over half of the world鈥檚 freshwater lakes are in decline, storing less water than three decades ago, according to a study led by researchers that was featured on the cover of Science.听
The scientists took a new approach, focusing on lake and reservoir water storage with data from nine different satellites鈥攐ver 250,000 images spanning three decades鈥� using an innovative technique to reconstruct past water storage data. They also identified the causes of lake water storage decline: climate change (including warming temperatures and reduced inflows leading to evaporation), human consumption and sedimentation in reservoirs.听
鈥淭his is the first comprehensive assessment of trends and drivers of global lake water storage variability based on an array of satellites and models,鈥� said lead author Fangfang Yao.
