Earth —
Climate change could drive extreme water-flow swings in major rivers. This would cause sharp declines and surges that may be more than five times higher than historical levels.
The projected upheaval points to the risk of fewer stable habitats, flood-prone flows, and fish communities being stranded.
River forecasts show shifting patterns
Across 32 downstream river monitoring points, daily flow records revealed how climate futures could remake the water patterns that river species depend on.
Qiusheng Ma at the Northeast Institute of Geography and Agroecology used the river records to link altered flows to habitat variety.
Projected water did not move gently, as some rivers lost regular seasonal flow while others gained more during the wet months.
That uneven pattern makes the next question biological, because fish survive through timing, depth, and speed – not water volume alone.
