AI Summary

A study from the University of Eastern Finland shows that the freshwater cycle is moving further from its stable state, driven by climate change and large‑scale water and land use. The research, published in *Nature Communications*, examined changes in blue water (streamflow) and green water (soil moisture) from 1901 to 2019. Using global hydrological model outputs, the authors separated the relative impacts of direct human forcing and climate‑related forcing on these water components. They analyzed the frequency of anomalously dry and wet conditions compared to a preindustrial‑like baseline, finding that the freshwater planetary boundary has deepened.
