The Human Fingerprint on Earth’s Water Cycle
Human activities have become intertwined with how water is distributed across the continents. A new study brings their effects into sharper focus.
Humans are exerting increasing influence over how water moves through lakes, rivers, soil, and the subsurface, and a new NASA study shows where those effects are greatest. Using more than two decades of satellite measurements of subtle changes in Earth’s gravity, the researchers sharpened the picture of how—and why—terrestrial water storage has changed.
