How Did We Miss 20% of Greenland’s Ice Loss?
The ice loss was hidden in places existing monitoring methods can’t reach, such as hard-to-map fjords. Machine learning helped scientist revise mass loss estimates and uncover patterns in glacial retreat.

Landfast Sea Ice: The Most Important Ice You’ve Never Heard Of
Landfast sea ice, sea ice that is held stationary against the Antarctic continent, links firmly with many key climate processes, but its importance is only being fully realized as its extent dwindles.
