In this lesson: Students build on these ideas by creating a physical model of the water cycle. Students use water, ice, and plastic wrap to model the ocean and cold upper atmosphere. Students use ...

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

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 ...
