Global River Changes: Rising Floods and Shifting Flows Unveiled

A new study has mapped the flow of water through the world's rivers over 35 years, revealing significant changes with major implications for water supply and flood risks. Nearly half of the largest downstream rivers have seen reduced flow, while 17% of smaller upstream rivers have increased flow, largely due to human activity and climate change. These changes affect freshwater availability, sediment transport, and flood risks, highlighting the need for better understanding and adaptation to these rapid shifts.

Perseverance rover discovers evidence of ancient Martian river.

NASA's Perseverance rover has found evidence of a once "rollicking river" on Mars in the Jezero Crater, indicated by curving rocks made of larger, coarse sediments. Scientists are debating what kind of powerfully flowing water formed those curves, and what this powerful waterway was like back when Mars was a warmer, bluer planet. The primary mission of the Perseverance rover is to seek out hints of life, if it ever existed, in an area that once harbored water.
