Astronomers have filled a large gap in knowledge about Mars' water cycle. Their research on water percolating from surface to aquifer could change the picture of what early Mars was like ...

How much water did Mars have in its ancient past and when did it disappear? This is what a recent study published in Geophysical Research Letters hopes to address as an international team of ...

Water constantly moves between the Earth and its atmosphere. But that system — called the hydrological cycle — is speeding up as global temperatures get hotter, primarily due to the burning of ...

Life Climate Change Speeding Up Water Cycle, Triggering Droughts and Deluges by Associated Press March 24, 2025, 9:33 a.m.

The idea of a “water cycle” also has a long history, and early sketches of the water cycle already included mountains, like the 1641 water cycle diagram by Kircher (Figure 1).

In ‘saving’ Blue Water, and neglecting Green Water, humankind has put a dent in the laws of nature, as the water cycle, for the first time in recorded history, has gone off balance.

A vicious cycle is at play: a steady supply of green water is essential for supporting vegetation that can store planet-heating carbon, but humanity's destructive path, including the destruction ...

The consequences will be even more catastrophic without urgent action. The water crisis threatens more than 50% of global food production and risks shaving an average of 8% off countries’ GDPs ...

Richard Allan, a climate science professor at Reading University, England, said the report “paints a grim picture of human-caused disruption to the global water cycle, the most precious natural ...

At aphelion, water has an abundance of less than one part per million in Mars’s skies, compared to more than 50 parts per million at perihelion. That, according to the Hubble and MAVEN data ...
