NASA scientists have uncovered significant changes in the global water cycle over the past two decades, largely driven by ...

The water cycle follows a cycle of evaporation, condensation, precipitation and collection. Water on Earth is always moving. It is constantly being recycled. This is called the water cycle.

In a recently published paper, NASA scientists use nearly 20 years of observations to show that the global water cycle is shifting in unprecedented ways. The majority of those shifts are driven by ...
