Ethan Pierce, Irina Overeem, and Bent Hasholt have unlocked an important clue in a long-standing scientific mystery.

Their new paper describes how icebergs export nutrients from Greenland into the Atlantic Ocean, a process that is being amplified by a warming climate.

The West Faces Snow Drought - NASA Science Very wetβ€”but very warmβ€”weather in the western U.S. has left many mountainous regions looking at substantial snowpack deficits.

Snow cover across the Western U.S. hit a record low earlier this month, as warm temps caused winter precipitation to fall as rain.
