The study indicates that roughly 21% of long-term river monitoring stations worldwide have observed significant changes in seasonal flow. This disruption is particularly evident during low flow periods, raising concerns about water security.

The research emphasizes a concerning trend in high northern latitudes (above 50 degrees North). In these regions, scientists observed a notable weakening in the seasonal flow cycle, directly attributing it to climate change. This disruption to the natural rhythm of rivers has far-reaching consequences.
